Description
Technical field
This utility model relates to a kind of welding wire, is specifically related to one and forges strand welding wire, belongs to welding technology field.
Background technology
Solder technology as a kind of important material processing technique, be widely used in machine-building, petrochemical industry, boats and ships,
The industry such as bridge, Aero-Space.Welding material mainly includes welding rod, welding wire, welding, solder flux, solder etc., along with China's welding certainly
Dynamicization level improves constantly, and the welding wire consumption adapting to automatic welding quickly increases.Improve the welding production of metal arc welding
Rate is the importance promoting solder technology development, and improving welding deposition rate is the important measures improving welding production power.Weldering
The size of filament diameter is the key factor of welding deposition rate.Require that there is certain flexibility and rigidity as welding wire, in order to be wound around
One-tenth dish, the welding wire straightening with certain crooked radian being in use wound on wire reel, there is certain rigidity,
To be sent to molten bath accurately.Traditional gage of wire is less, is not easy to the welding of band large-scale metal component, but excessive welding wire
Diameter has a strong impact on the flexibility of welding wire, will be unable to into dish, even if one-tenth dish, is in use difficult to energy consumption during straightening, and use
Excessive, this is unfavorable for production and processing.
The utility model patent of Application No. 200920045272.8 discloses a kind of multi-strand stranded welding wire, and it includes real core
Welding wire and flux-cored wire, a root wire is positioned at centre, referred to as core wire；Remaining welding wire is stranded around middle core wire, is referred to as
Peripheral silk.This stranded electrode has the advantage that
1, not changing the constituent structure of original welding material, production process is the machining of stranded manufacture, to environment not
Cause any pollution；
2, welding arc belongs to continuous rotary arc, and molten bath realizes stirring in real time, and molten bath is uniform, molten drop fine grained many electric arc mistake
Degree, Weld Performance quality increases substantially, each root wire fusing moment splash brought into by rotating the arc molten bath is formed almost without
The welding process splashed, the workload of road polishing operation after a large amount of minimizings, welding process smog is greatly reduced；
3, required energy consumption is low, and under equal welding conditions, gage of wire can significantly increase slightly, is different from existing filament diameter
After increasing energy consumption increase and coiling property in practical operation, can wire feeding property be poor, be difficult to normal weld；
4, with tradition welding wire than requirement according to different process under equal energy consumption condition change the structure of each monofilament, quantity and
Diameter is arranged in pairs or groups, easily realize having that deposition efficiency is high, heat input is relatively low, welding penetration is big, low dilution rate, operation the simplest,
It is especially suitable for big specification, the welding of high filling, at high speed deposition, fundamentally overturns traditional welding procedure；
5, material composition easily regulates and controls, and changes a certain monofilament composition therein or logical in stranding process multifibres as required
Crossing stranded any flux-cored wire of entering, meeting the composition required for technique by the medicated powder formula of flux-cored wire can be light
Easily reach technological requirement, need to be completed by melting if desired for changing composition compared with monofilament, simplify operating process and wholesale
Cost savings, especially require to provide subversiveness measure convenient to operate for solution special process.
Although above-mentioned multi-strand stranded welding wire can solve the problem that tradition gage of wire is big not, diameter is difficult to when increasing coil, just
The problems such as straightforward difference, energy consumption are high, deposition rate is low, welding quality is uneven, but itself yet suffer from following shortcoming:
1, electric conductivity
Cable shape form longitudinally presents dotted line, and welding process contact as Multi-contact with ignition tip, causes the very difficult guarantor of electric conductivity
Holding seriality, easily cause current interruption phenomenon, between the too high rear welding wire of operating process heat and ignition tip, space change causes conduction
Bad being easier to causes short circuit to form the viscous extremely plug wire of welding wire in ignition tip inside or gooseneck in advance；
2, frictional force
Owing to formalness is cable shape, longitudinally running with the friction between ignition tip just as file, make wire feed process
In steeply rise with the equipment auxiliary degree of injury of strand welding wire traffic direction CONTACT WITH FRICTION, consumable accessory use cost increases in a large number
Add, and cable shape form is poor with conventional support equipment and auxiliary compatibility, improve difficulty big, repetition fund need to be put into and again open
Open up NPD projects supporting；
3, welding process gas shield performance
Due to the helical groove on surface, welding gun and wire-feed motor junction, strand welding wire is protected after wire-feed motor enters welding gun
Gas reversely spills wire-feed motor outlet mouth along strand welding wire helical groove, causes the ignition tip end gas shield of welding gun to rise
To sufficient gas shield effect, weld seam easily produces pore, it addition, be that and then welding wire send together in protective gas work process
Going out, owing to the quick wire feed of strand welding wire is to form helical airflow, protective gas also becomes to rotate state, easily when protection set ejection
Cause face of weld to protect the quality of not overall effect weld seam, and allow protective gas run off in a large number to cause waste；
4, surface manufacture process control difficulty
Cable shape strand welding wire stranding process requires higher, otherwise for smooth fineness and the string diameter of every monofilament surface
The stranded welding wire completed is it is difficult to ensure that the required precision of quality of finished, and the easy residual impurity of groove part, between each monofilament
Slag inclusion is difficult to clean out in a pipeline, causes and affects weldquality in later stage welding process；
5, welding process molten bath controls difficulty
Welding process, along with the increase electric arc spin even faster of wire feed rate, adds the stranded not tight rotary arc amplitude of welding wire relatively
Easily causing greatly electric arc not concentrate, welding pool cannot advance toward fusion penetration direction, and a large amount of deposited metals, toward molten cross direction extension, are made
Become meaningless waste, and be difficulty with normal welding effect requirement；
6, the impact on the process of use of the coiling gap is manufactured
Cable shape strand wire reel is wound in finished product wire reel, due to the gap of helical groove, the coiling weight in equal space
To reduce with length, and cause packing cost to increase, use process changes dish frequency to be increased, and residual loss is consequently increased, and uses into
This increase；
7, the impact of internal memory stress
Monofilament due to deformation, causes the stranded strand welding wire completed to there is bigger stress, is coiled in stranding process
Overtension in wire tray, easily dissipates dish, the packaging of manufacture and use process, rewind, coils, dismounts and change difficulty relatively with wire tray
Greatly；
8, the string diameter after stranded controls error precision
The diameter of cable shape strand welding wire has with the gap between every monofilament and connected monofilament and definitely associates, and adds stranded complete
After one-tenth due to stress act on deposit during it also occur that deformation, so the string diameter trueness error of cable shape strand welding wire controls
Extremely difficult；
9, welding wire manufacturing process and the control of production cost
Owing to the overall quality of cable shape strand welding wire depends on the control of every monofilament manufacture process, from monofilament to strand mistake
Cheng Bixu repeats to set up control flow, it is impossible to simplify the manufacturing step in each flow process, so manpower and materials put into bigger relatively.
