Abstract
The utility model discloses a welding device for argon arc welding. The welding device comprises a shell for accommodating argon. The shell is provided with an opening for a welding component to be inserted in. The shell is also provided with a working window for a welding gun to work. Due to the adoption of the welding device, the whole welding process can be ensured to be carried out in the pure argon atmosphere without being in contact with the air, so that total argon protection on a welding line molten pool is realized, the argon protection effect on the welding line molten pool and the crystallizing process is effectively improved, the generation of welding defects such as air pores and the like is avoided fundamentally, the welding line quality is greatly improved, and thus, the qualification rate of the welding component is obviously improved.
Description
Technical field
The utility model belongs to technical field of welding equipment, is specifically related to a kind of argon arc welding welder.
Background technology
At present generally all adopt the argon arc welding procedure, promptly in welding process, adopt in torch neck ejection hyperbola column argon gas stream to realize protection welding pool for the welding of hardware weld seams such as aluminum or aluminum alloy.In present argon arc welding procedure; owing to be subjected to the influence of factors such as argon stream size, shape, dynamic instability; can not realize the complete argon shield of butt welded seam molten bath and crystallization process; there is wild effect in the weldquality that this welding procedure welding obtains; often there is airborne pernicious gas to enter the weld seam molten bath and causes the commissure to produce weld defects such as welding pore, therefore adopt the qualification rate of the hardwares such as aluminum or aluminum alloy that existing argon arc welding procedure makes low.At present for the high hardwares such as aluminum or aluminum alloy of requirement on machining accuracy, for example play the hardwares such as shaft-like aluminum or aluminum alloy of slipper seal gas effect, the welding quality that how to improve its weld seam also is puzzlement processing personnel's a technical barrier with the qualification rate that improves product always.
Summary of the invention
The purpose of this utility model is to provide a kind of argon arc welding welder.
In order to realize above purpose, the technical scheme that the utility model adopted is: a kind of argon arc welding welder, comprise that one is used to hold the housing of argon gas, described housing is provided with the perforate that is used to insert welded unit, also is provided with the operation window that is used for welding gun work on the described housing.
Further, described housing is a cylindrical shape, the end sealing of housing, and the other end is provided with the perforate that is used to insert welded unit, and the sidewall of described housing is provided with the operation window that is used for welding gun work.
Described housing is a cylindrical shape, the two ends of housing are provided with capping, wherein the capping of an end is provided with the perforate that is used to insert welded unit, and the position near sidewall in the described capping also is provided with the argon gas inlet, and the sidewall of described housing is provided with the operation window that is used for welding gun work.
The welder that adopts the utility model to provide, when welding, utilize the character of the proportion of argon gas greater than air, bottom at the housing of this welder charges into argon gas in housing, charge into certain hour so that the air in the housing is expelled totally fully, continue to charge into argon gas afterwards in housing, this moment, the weld with member to be welded was inserted in this welder, and weld aimed at the operation window of welding gun, welding gun is extend into from operation window finish welding job in the housing afterwards.Adopt the utility model can guarantee that whole welding process all carries out in pure argon atmosphere; can not contact with air; realized the complete argon shield in butt welded seam molten bath; effectively raise the argon shield effect of butt welded seam molten bath and crystallization process; fundamentally avoided the generation of weld defects such as pore; improve weldquality greatly, thereby significantly improved the qualification rate of welded unit.

The specific embodiment
Embodiment 1
As shown in Figure 1, a kind of argon arc welding uses welder, this welder to comprise that one is used to hold the cylindrical shell 7 of argon gas, the end sealing of housing 7, the other end is provided with the perforate 9 that is used to insert welded unit, also is provided with the operation window 3 that is used for welding gun work on the sidewall of housing 7.
The argon arc welding that present embodiment provides is seen shown in Figure 2 with the user mode schematic diagram of welder, when welding, utilize the character of the proportion of argon gas greater than air, in housing 7, charge into argon gas in the bottom of the housing 7 of welder by tunger tube 6, charge into certain hour so that the air in the housing 7 is expelled totally fully, continue in housing, to charge into argon gas afterwards, this moment, the weld 4 with aluminium alloy element to be welded 2 was inserted in the housing 7 by perforate 9, and weld 4 aimed at the operation window 3 of welding guns 5, welding gun 5 is extend in the housing 7 from operation window 3 finish welding job afterwards.Adopt the utility model can guarantee that whole welding process all carries out in pure argon atmosphere; can not contact with air; realized the complete argon shield in butt welded seam molten bath; effectively raise the argon shield effect of butt welded seam molten bath and crystallization process; fundamentally avoided the generation of weld defects such as pore; improve weldquality greatly, thereby significantly improved the qualification rate of aluminium alloy element product.
Embodiment 2
As shown in Figure 3, a kind of argon arc welding welder, this welder comprises that one is used to hold the cylindrical shell 7 of argon gas, the two ends of housing 7 are provided with capping 12, wherein the capping 12 of an end is provided with the perforate 9 that is used to insert welded unit, position near sidewall in the capping also is provided with argon gas inlet 11, and the sidewall of housing 7 is provided with the operation window 3 that is used for welding gun work.
