Problems solved by technology

[0006] However, welding heads with permanently connected shielding gas devices are used in welding fillet welds or irregular welds, such as figure 2 , due to the fixed position of the shielding gas device, it is impossible to adjust the position of the shielding gas outlet according to the actual situation of the solder joint, so that the shielding gas blown out of the shielding gas outlet pipe 23 either cannot blow to the weld, or the shielding gas outlet pipe 23 collides with the workpiece, The welding of fillet welds or irregular welds cannot be effectively realized

Abstract

The invention provides a welding shield gas device. The device comprises a mounting base which is connected and fixed with a welding joint and an air outlet pipe which is arranged on the mounting base and is used for releasing shield gas, wherein an adjusting device used for adjusting the position of the air outlet pipe is arranged between the mounting base and the air outlet pipe. The welding shield gas device ensures that the air outlet pipe can adjust the air outlet position of the shield gas according to the actual situation of welding spots by arranging the adjusting device used for adjusting the position of the air outlet pipe between the mounting base and the air outlet pipe, thereby effectively realizing the welding of fillet welds or irregular welds, and obtaining the weld appearance which meets the welding process requirement and the welding quality which meets the strength requirement.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to a welding shielding gas device. Background technique [0002] In the application design process of laser high-power CO2 laser welding, there are many types of welding products. Due to the different structures of welding products, the welding methods are also different, such as: butt welding, fillet welding, lap welding, etc. The butt weld is generally two flat plates butt welded. In this case, the product structure is simple, and satisfactory results can be obtained by using our general welding head. If a fillet weld or a complex weld is encountered and the weld is irregular, the welding shielding gas will either not blow to the weld, or the shielding gas outlet pipe will collide with the workpiece. [0003] In the welding process, in order to achieve the best weld appearance and weld quality that meets the strength requirements, a welding shielding gas device is generally used...
