Problems solved by technology

[0012] Although there are many technologies on the market that claim to prevent welding spatter sticking, none of them can guarantee 100% effectiveness
Moreover, once the welding slag is bonded, it is very difficult to clean it.

Abstract

The invention discloses a fusion electrode gas protection welding gun, and belongs to the technical field of welding. The welding gun structurally comprises a gun body front end, a current contact nozzle, a current contact nozzle base and a nozzle; the current contact nozzle is arranged on the front end of a gun body through the current contact nozzle base, nozzle is arranged on the current contact nozzle and the current contact nozzle base in a sleeving manner, and is connected with the gun body front end, and the welding gun is characterized in that a nozzle lining casing pipe is arranged onthe inner side of the nozzle, and the nozzle lining casing pipe and the outer contour of the current contact nozzle base form a welding slag isolation cavity. Compared with the prior art, the fusionelectrode gas protection welding gun has the advantages that welding slag is easy to clear, welding gas cannot be polluted by air, and the gun has the good popularization and application value.

Description

technical field [0001] The invention relates to the field of welding technology, and specifically provides a MIG shielded welding torch. Background technique [0002] Gas metal arc welding (GMAW) is a welding method commonly used in industry today. The welding torch is connected to the power supply through the cable to provide current to generate an arc between the contact tip and the workpiece for welding. The gas path of the welding torch provides shielding gas to shield and protect the welding area. The shielding gas can usually be helium, carbon dioxide, other inert gases, semi-inert gases and other mixed gases suitable for "MIG". Metal arc welding (MAG) is also widely used. The gas mixture used by MAG is not an inert gas. For example, some gas mixtures contain oxygen. [0003] The inert gas used in MIG welding serves two purposes. First, shield the welding area to avoid oxygen and nitrogen in the air from contacting the welding area, and these gases usually cause ...
