The embodiment of the invention discloses a welding gun of lockhole effect TIG deep penetration welding. The welding gun comprises a welding gun body. The top of the welding gun body is fixedly connected with a welding gun outer cylinder through a locking nut. A shaft sleeve is arranged in the welding gun outer cylinder. A conducting rod is arranged in the shaft sleeve. The bottom of the conducting rod is connected with an electrode head through a mounting seat. A tungsten electrode is arranged in the electrode head through a locking positioning sleeve and a positioning nut. The outer wall of the electrode head is further sleeved with an inner sleeve and a first air nozzle. The first air nozzle is sleeved with a second air nozzle. The second air nozzle is connected with the welding gun body through the locking nut. By the adoption of the welding gun, deep penetration welding of the lockhole effect can be achieved, welding efficiency is greatly improved, meanwhile even if a welding plate to be welded is quite thick, beveling is not needed, and filler wires are not needed either, so that the welding cost is greatly saved, and the welding gun has huge industrial application value.
Description
technical field [0001] The invention relates to the field of welding technology, in particular to a keyhole effect TIG deep penetration welding torch. Background technique [0002] TIG welding (Tungsten Inert Gas arc Welding), also known as inert gas tungsten shielded welding, is a mature welding method and is widely used in the welding fields of carbon steel, stainless steel, aluminum alloy and non-ferrous metal materials. Ordinary TIG welding has a stable arc and good welding quality, but its penetration is shallow, the welding speed is slow, and the efficiency is low. For example, for stainless steel or titanium alloy, the maximum penetration depth of one welding can only reach about 4mm. Therefore, TIG welding is generally used for thin plate welding or bottom penetration weld bead root welding of thick-walled important components. [0003] For medium-thickness (>4mm) metal plates, it is necessary to open a corresponding angle groove 1 at the joint according to the ...
