Description

DESCRIPTION INTERNAL THREADED STUD FASTENER WELDING METHOD TECHNICAL FIELD The invention is used to weld studs with a diameter of 10 mm or larger by stud welding method. providing a smooth weld surface and increasing the weld penetration, which shortens the welding time and does not use consumables (welding wire). The fastener is related to the welding method.

The invention especially; Stud welding with pull-on method to the surface to be welded a smooth weld surface and weld penetration. a certain amount as soon as the trigger of the stud gun is pressed. by pulling welded internal threaded fastener with the welding method. KNOWN STATE OF THE TECHNIQUE Welding, especially used for joining metal and thermoplastic materials. is a method. It has an intense usage area for manufacturing purposes. Separate heat and pressure Combination is made by using them separately or together. kind or melt The addition of a material whose intervals are the same or very close to each other. The process made by metal welding is called metal welding. Usually metal materials the technique of melting and joining with an added filling material used. Welding is a holistic action consisting of various processes and different strength and melting standards depend on its specific technical uses in this field. causes it to be divided into varieties.

Internal thread used as a welded connection element in vehicle bodies in the current technique. The studs are welded with traditional methods, MAG/MIG. This resource Internal threaded studs welded with all-round corner welding method It is welded using welding wire. With this welding method, the internal threaded stud only a certain amount is melted from the outer area. Full 'source' cannot be provided. Also, internal threaded studs are affected by post-weld heat. region (HAZ) is wider. Mechanical properties of the base material in the HAZ region is damaged.

In the current technique, external threaded stud fasteners are also used with the stud welding method. is boiled. With this welding method, max. Distal gear up to D=10 mm diameter The studs are welded with gas shielding without the use of welding wire. this type To provide additional connection surface during mounting to the studs, the so-called spacer fasteners may need to be twisted. Distant threaded stud type threads rust, dirt, oil etc. A coating must be applied to protect it from situations. General In vehicle process flow, this coating may be damaged and the stud may corrode.

As a result, for the solution of the above-mentioned problems existing in the current art, the need for a new economical, convenient, fastener and the existing The inadequacy of the solutions made it necessary to make an improvement in the related technical field.

OBJECTIVE OF THE INVENTION The present invention is aimed at eliminating the above mentioned disadvantages and providing the relevant technical field. 10 mm or larger diameter studs developed to bring new advantages, providing a smooth welding surface when welding with the stud welding method and increase the weld penetration, shorten the welding time, consumable The connector that ensures that it is not used (welding wire) is related to the welding method.

The most important object of the invention is to make the all-round welding process very easy to internal threaded studs. facilitating full penetration. Chamfer and ignition tip on their heads Full resource penetration is ensured. In this way, special production is internally It has been ensured that larger diameter requirements of threaded stud can be welded. of the machine can weld max. D=16mm diameter is used in the welding area. Design on the side to be used for mounting purposes of the large diameter stud required used. Both weldability and assembly with this stepped stud design availability is assured.

Another important object of the invention is the particle shielding of stepped internal threaded studs, air conditioning, It enables it to be used in assembly places such as stacking. These mentioned equipment Large connection surfaces are often required for this.

Another important object of the invention is to use internal threaded studs in aluminum body vehicles. high quantity of fasteners such as insulation mounting place using fastener In cases where it is used, the material is mechanically used by saving process time. to preserve its properties.

Another important object of the invention is the use of armored materials (steel or aluminum). It enables the welding process to be carried out without disturbing its mechanical properties. internal thread Since no extra welding wire is used in the stud process and the welding time is normal The heat-affected zone (HAZ) is very narrow because it is shorter than the source. Like this There is no deterioration in mechanical properties.

The structural and characteristic features and all advantages of the invention are given in the following figures and more clearly thanks to the detailed explanation written by making references to these figures. will be understood and therefore the evaluation should also take into account these figures and detailed explanation. should be done with consideration.

FIGURES TO HELP UNDERSTAND THE INVENTION FIGURE 1; The subject of the invention is the drawing showing the fastener welding method.

REFERENCE NUMBERS . Internal Threaded Stud 11. Chamfer 12. Ignition Tip . Surface to be Welded DETAILED DESCRIPTION OF THE INVENTION In this detailed explanation, in welding studs by stud welding method, connection, which provides a smooth weld surface and increased weld penetration. preferred embodiments of the element welding method only for understanding and without any limiting effect is explained.

Figure 1 shows the inventive welding method. Internal threaded studs in the invention (10) is welded to the surface (20) to be welded using the stud welding process.

In this stud welding process, the stud gun is used with the pull-engagement method. As soon as the trigger is pressed, the internal threaded stud (10) is pulled up a certain amount. This In this way, the ignition tip (12) located at the end of the internal threaded stud (10) creates an arc. melts the bottom of the material and welds the stud to the base material. Own our standard internal threaded studs min. D=11mm max. D=16mm in size. Welding as they have chamfer (11) and ignition tip (12) on their heads. penetration is better. Thus, larger diameter threaded studs (10), in welding with the stud welding method, by shortening the welding time. A smooth welding surface is provided. Also in the internal threaded stud (10), this design All-round welding is provided more easily. Our invention is a larger diameter internal thread It is designed for welding studs (10). Welding of the machine the max. D=16mm diameter is used in the welding area. In our invention we also both weldability and mountability with stepped stud design has been provided. A stronger weld surface with full penetration in our invention it provides.

In our invention, by using internal threaded stud (10), in aluminum body vehicles, In cases where high amount of fasteners are used, such as insulation mounting location, both process time is saved and the mechanical properties of the main material is protected.

Since no extra welding wire is used in the internal threaded stud (10) welding process and affected by the heat as the welding time is shorter than the normal nut welding zone (HAZ) is very narrow. Thanks to this feature, armor-specific materials (steel or aluminum) does not degrade its mechanical properties.

The scope of protection of this application has been determined in the claims section and It cannot be limited to what is described for exemplary purposes, in the invention of a person skilled in the art. that the innovation can be demonstrated by using similar structures and/or that this structuring can be applied to other fields with similar purposes used in the related technique. It is open. Therefore, the innovation of such structuring and especially the state of the art It is also obvious that it will lack the criterion of being suspended.
