The high melting point material may include graphite, molybdenum disulfide, tungsten disulfide, or boron nitride. The lubricant is configured to remain on the lubricant-coated wire electrode without melting when the pre-heater heats the wire electrode to a high temperature (e.g., between 500 degrees celsius and 900 degrees celsius). The lubricant may be a powder or a liquid. When the lubricant is a liquid, the liquid may further comprise a solvent, such as 2-propanol or water.
Description
Cross Reference to Related Applications
The present application claims the benefit of priority from U.S. provisional patent application No. 63/416320 filed on 10/14 2022, which is incorporated herein by reference in its entirety.
Technical Field
The present disclosure relates generally to high temperature lubricants used in preheated welding wire systems.
Background
Welding is a process that is becoming more and more common in all industries. Welding is by its very nature the way two pieces of metal are joined. A wide variety of welding systems and welding control schemes have been implemented for various purposes. In continuous welding operations, metal Inert Gas (MIG) welding and Submerged Arc Welding (SAW) techniques allow for a continuous bead to be formed by feeding a welding wire shielded by inert gas or granular flux from a welding torch. The wire feed system may be used in other welding systems, such as Tungsten Inert Gas (TIG) welding. Power is applied to the wire and the electrical circuit is completed through the workpiece to maintain a welding arc that melts the wire electrode and the workpiece to form the desired weld.
Existing wire lubricants include low melting point lubricants such as petroleum distillates, oils, soaps, waxes or detergents. One example is sodium stearate. When used in preheated welding wire systems, these low melting point lubricants tend to melt in the preheating zone, which may subsequently clog the welding gun and cause the welding wire to stop feeding or not feed properly. This may lead to downtime when correcting the problem, which may offset some of the advantages of using a preheated welding wire system.
There is a need for an improved high temperature lubricant for use in preheated welding wire systems.
Disclosure of Invention
The present disclosure relates generally to high temperature lubricants used in preheated welding wire systems and related systems and methods.
According to one aspect of the present disclosure, a lubricant for coating a wire electrode to be used in a preheated wire system comprises one or more high melting point materials in a concentration of from 0.5wt% to 30wt% by weight of the lubricant. The one or more high melting point materials include graphite, molybdenum disulfide, tungsten disulfide, or boron nitride. The lubricant is configured to remain on the lubricant-coated wire electrode without melting when the pre-heater heats the wire electrode to between 500 degrees celsius and 900 degrees celsius. The lubricant may be a powder or a liquid. When the lubricant is a liquid, the liquid may comprise a solvent, such as 2-propanol (2-propanol) or water. The lubricant may contain up to 5wt% by weight of binders, dispersants, surfactants or petroleum distillates. In such lubricants, the binder may be a cellulosic resin or a thermoplastic resin.
In accordance with another aspect of the present disclosure, a preheated welding wire system includes a welding wire electrode and a preheater configured to heat the welding wire electrode to between 500 degrees celsius and 900 degrees celsius. The wire electrode is coated in a high temperature lubricant to form a coating on the outer surface of the wire electrode. The coating is configured to remain on the wire electrode without melting when the pre-heater heats the wire electrode to between 500 degrees celsius and 900 degrees celsius.

As used herein, preheating refers to heating the wire electrode prior to welding arc or deposition on the wire electrode's travel path.
The preheated welding wire system may include a welding wire electrode and a preheater configured to heat the welding wire electrode to between 500 degrees celsius and 900 degrees celsius. The system may be configured for use in a high deposition rate welding process. The wire electrode is coated in a high temperature lubricant to form a coating on the outer surface of the wire electrode. The coating is configured to remain on the wire electrode without melting when the pre-heater heats the wire electrode to between 500 degrees celsius and 900 degrees celsius.
Fig. 1 is a block diagram showing preheating and welding current paths in a conventional welding system 200 using resistive preheating. The conventional welding system 200 includes a welding torch 201 having a first contact tip 202 and a second contact tip 204. The system 200 further includes a wire electrode 114 fed from a wire spool 206, a pre-heating power supply 208, and a welding power supply 210. The system 200 is shown in operation as generating a welding arc 212 between the wire electrode 114 and the workpiece 106.
In operation, the wire electrode 114 passes from the wire spool 206 through the second contact tip 204 and the first contact tip 202, between which a pre-heating power supply 208 generates a pre-heating current to heat the wire electrode 114. Specifically, in the configuration shown in fig. 1, the preheat current enters the wire electrode 114 via the second contact tip 204 and exits via the first contact tip 202. At the first contact tip 202, welding current may also enter the wire electrode 114. The welding current is generated or otherwise provided by the welding power supply 210. The welding current exits the wire electrode 114 and returns via the workpiece 106. When the wire electrode 114 is in contact with the target metal workpiece 106, the electrical circuit is completed and welding current flows through the wire electrode 114, past the metal workpiece(s) 106 and back to the welding power supply 210. The welding current melts the wire electrode 114 and the parent metal of the workpiece(s) 106 in contact with the wire electrode 114, thereby engaging the workpiece as the melt solidifies. By preheating the wire electrode 114, a welding arc 212 with reduced arc energy may be generated. In general, the preheat current is proportional to the distance between contact tips 202, 204 and wire electrode 114.
The welding current is generated or otherwise provided by the welding power supply 210, while the preheating current is generated or otherwise provided by the preheating power supply 208. The pre-heating power supply 208 and the welding power supply 210 may ultimately share a common power source (e.g., a common generator or line current connection), but the current from the common power source is converted, inverted, and/or regulated to produce two separate currents, the pre-heating current and the welding current. For example, a single power supply and associated inverter circuitry may be utilized to facilitate the preheating operation, in which case three leads may extend from the single power supply.
During operation, the system 200 establishes the welding circuit 214 to conduct a welding current, which is shown by the welding current path 216. A welding current path 216 flows from the welding power supply 210 to the first contact tip 202 and returns to the welding power supply 210 via the welding arc 212, the workpiece 106, and the work lead 218. To enable connection between the welding power supply 210 and the first contact tip 202 and the workpiece 106, the welding power supply 210 includes terminals 220, 222 (e.g., positive and negative terminals).
During operation, the pre-heating power supply establishes a pre-heating circuit to conduct a pre-heating current through the section 226 of the wire electrode 114, the pre-heating current represented by the pre-heating path 224. To enable connection between the pre-heating power supply 208 and the contact tips 202, 204, the pre-heating power supply 208 includes terminals 228, 230. The preheat current path 224 flows from the welding power supply 210 to the second contact tip 204, the section 226 of the wire electrode 114, the first contact tip 202, and back to the preheat power supply 208 via a cable 232 connecting the terminal 220 of the welding power supply 210 to the terminal 230 of the preheat power supply 208.
Because the preheat current path 224 overlaps the weld current path 216 on the connection between the first contact tip 202 and the power supplies 208, 210, the cable 232 may enable a more cost-effective single connection (e.g., a single cable) between the first contact tip 202 and the power supplies 208, 210 rather than providing separate connections for weld current to the first contact tip 202 and preheat current to the first contact tip 202.
The wire 114 may be heated to a pre-heating temperature. This preheating temperature may be, for example, in the range of 500 to 900, or 650 to 850, or 600 to 800, or 650 to 750 degrees celsius.
Further details regarding preheated welding systems can be found in U.S. patent publication nos. 2017/0165778A1 and 2018/0354055A1, and each of the patent publications is incorporated herein by reference.
Fig. 2 illustrates a method 100 for forming and using a wire electrode. The method includes forming 120 a wire electrode and then applying 140 a high temperature lubricant to the wire electrode to form a coating on an outer surface of the wire electrode. At this point, the manufacture of the wire electrode may end. To use the wire in a preheated welding system, 160 preheats the wire electrode to between 500 degrees celsius and 900 degrees celsius before 180 welding using the wire electrode. The coating is configured to remain on the wire electrode without melting during the preheating step 160.
The wire electrode may comprise one or more high melting point materials. The one or more high melting point materials may be present at a concentration of from 0.5wt% to 30wt%, 1.0wt% to 25wt%, 2.0wt% to 20wt%, 3.0wt% to 15wt%, or 5.0wt% to 10wt% lubricant. The one or more refractory materials may include graphite, molybdenum disulfide, tungsten disulfide, or boron nitride. In particular, graphite has the advantage of having a high melting point and being electrically conductive, which is an advantage in arc welding using a welding wire. Graphite and molybdenum disulfide have high lubricity for mating parts to tight tolerances that make each a high performance component in lubricants for welding wire applications, especially when evaluated for long periods of time in high demand industrial applications. The lubricant may contain more than one high temperature, high melting point material to optimize design. Other high melting point materials that may be used as lubricants are materials having a melting point of 600 degrees celsius or more, or 900 degrees celsius or more, particularly when the welding wire is to be preheated to between 600 degrees celsius and 900 degrees celsius.
The high melting point material may allow for ultra-thin film coatings, especially when applied with a liquid medium. The coating may not always be a continuous coating, but may be present in the form of stripes and patches on the surface of the wire electrode. This is often acceptable and not detrimental to its end use. The high melting point material dissolved in the liquid medium has the advantages that: the precise and controlled amount of coating on the surface of the wire electrode is achieved using a variety of well-designed application systems. This may help achieve a low or ultra low amount of lubricant coating on the welding wire, which may help avoid lubricant build up in the welding gun.
High melting point materials dissolved in 2-propanol or other media having a low flash point have a fast cure time, which may be advantageous in the manufacturing process of the welding wire. A low flash point medium may also be advantageous in manufacturing cored welding wire with a longitudinal seam because if the medium enters the core, it will evaporate.
High melting point materials (sometimes also referred to as dry lubricants) have additional advantages over other lubricants such as stearates and oils typically used in welding wire. This additional advantage is that the high melting point material is free of hydrocarbons. Hydrocarbons may increase the diffusible hydrogen content of the steel weld metal, which is undesirable.
The lubricant may be a powder or a liquid. When the lubricant is a powder, it may contain a single component or a powder mixture. While binders, dispersants, and other additives in the high temperature lubricant mixture may be used to obtain a good uniform and adherent coating on the welding wire, such additives may not be needed to obtain a welding wire with the proper properties of the high temperature lubricant coating for the preheating system. For example, the powder coating (without liquid and without additives) on the welding wire may have sufficient properties.
When the lubricant is a liquid, the liquid may comprise a solvent, such as 2-propanol or water. The lubricant may contain up to 25wt% of binders, dispersants, surfactants or petroleum distillates. For example, the lubricant may comprise up to 5wt% of a binder, up to 5wt% of a dispersant, up to 5wt% of a surfactant, and up to 5wt% of a petroleum distillate. In the liquid lubricant, the binder may be a cellulose resin or a thermoplastic resin. These additional additives (such as binders and dispersants) can help to obtain a good, uniform and adherent coating on the wire electrode. The lubricant may be applied in liquid form using solvents other than 2-propanol or water. In this case, a process such as baking may be used during the manufacturing process of the wire electrode to remove solvent from the wire while allowing the high temperature lubricant to remain. In this method, the solvent is harmless when used to apply the high temperature lubricant to the wire electrode used with the preheating system.
Binders, dispersants, and other additives are typically low melting temperature materials (such as thermoplastic resins) and may be disadvantageous in preheated welding systems if their amounts are not kept to a minimum on the wire surface. For example, the binder, dispersant, surfactant, and petroleum distillate may be materials having melting points below 500 degrees celsius. Minimization of low melting temperature additives on the wire surface may be achieved by reducing the concentration of the low melting temperature additives in the mixture, reducing the amount of the mixture applied to the wire, or by baking the wire during the manufacturing process (after the high temperature lubricant dissolved in 2-propanol or other solvent with additives has been applied to the wire) between about 400 degrees celsius and 600 degrees celsius. It may not be necessary to add additives to the lubricant.
According to a further aspect of the invention, a very low melting point lubricant or material may be used that will evaporate or liquefy harmlessly in the preheated section of the welding gun so that it does not clog the welding gun.
According to further aspects of the invention, mating parts of the welding gun may be lubricated so that the welding wire does not require a lubricant. In this case, the lubricant would be applied to the liner, insulator tubing, contact tips, and other components of the welding gun.
The electrode may be metal cored, solid or flux cored. The metal core or flux core electrode may be with or without seams. The electrode may have an external metal coating, such as a copper coating, or may be devoid of an external metal coating.
The various aspects and embodiments disclosed herein are not intended to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented herein. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the figures, could be arranged, substituted, combined, separated, and designed in a wide variety of different configurations, all of which are contemplated herein.
