Argon arc welding is mainly used for welding aluminum and aluminum alloys, copper and copper alloys, magnesium and magnesium alloys, titanium and titanium alloys, superalloys, etc. It is widely used in many important industrial sectors. Besides electric shock, burn and fire similar to covered electrode arc welding, argon arc welding also has high-frequency electromagnetic field, click radioactivity and arc damage which are much stronger than arc welding.
Extended data:
When using the welding torch, you must first check the suction performance and air tightness, and the connecting parts, air passages and regulating valves of the welding torch must not be stained with grease.
When the welding torch is ignited, the acetylene valve should be opened first, and then the oxygen valve should be opened to adjust the flame; When turning off the fire, acetylene should be turned off first, then oxygen. When stopping use, it is forbidden to permanently connect the welding torch, hose and air source.
When using the cutting torch, the paint and rust layer on the working face should be cleaned, and it is not allowed to work on the cement floor, so as to avoid splashing rust-proof water and cement at high temperature.
When the cutting torch is ignited, an ignition test should be conducted first to check whether the cutting nozzle is installed correctly. When flameout, acetylene should be turned off first, then oxygen.
