Holster of argon arc welding gun special for narrow gaps and deep grooves

Abstract

The invention provides a holster of an argon arc welding gun special for narrow gaps and deep grooves, and belongs to the field of welding. The holster of the argon arc welding gun special for the narrow gaps and the deep grooves comprises a sleeve, a gun grip, a baffle, two nuts, bolts and a protective device, the gun grip is welded vertically to the tail end of the sleeve, the baffle is welded vertically to the front end of the sleeve, and the baffle and the gun grip are parallel to each other, the protective device sleeves the outer side of the baffle, holes are evenly formed in the top endof the sleeve, the two nuts are arranged at the top end of the sleeve, and the nuts are matched with the bolts to fix a welding gun. According to the holster of the argon arc welding gun special forthe narrow gaps and the deep grooves, an original straight pen gun is simply assembled, thus the argon arc welding gun holster and the original straight pen gun are integrated into one, by changing the way of holding the gun, and additionally arranging the thermal insulation protective device on the gun grip, baking of hands of welders by the high temperature can be effectively avoided, thus the welders can operate continuously and freely, high-quality weld joints are easy to obtain, the investment is low, but the big problems in the production practice can be solved.

Description

technical field [0001] The invention relates to a special argon arc welding gun holster for narrow gaps and deep grooves, which belongs to the field of welding. Background technique [0002] At present, the 90-degree argon arc welding torch produced by welding equipment manufacturers is only suitable for products with a thickness of less than 50mm. When argon arc welding is required for products with a thickness greater than 50mm, a straight argon arc welding torch is usually used. Because products of this thickness need to be preheated at 100-250°C. This will cause a large number of heat bands to gather and rise along the direction of the groove when the welder seals the back. Even if the welder wears gloves, he cannot withstand such a high temperature, which will cause the welder to be unable to hold the welding torch, and the operation process is extremely unstable. The seam shape is not beautiful, it is easy to produce cracks, pores and lack of fusion, and the quality o...
