Manual aluminum spot welding is a kind of resistance welding, mainly used for welding of aluminum alloy, use of current through welding parts and nearby areas generated resistance heat as a heat source to locally heat workpiece, while pressurizing workpiece to form a metal bonding method. The structure of manual aluminum spot welding gun is roughly the same as that of the manual steel spot welding gun. It is that manual integrated welding gun is suspended under I-steel, and weight of welding gun is balanced by spring balancer. The worker holds welding gun by hand, slides around and forward through longitudinal and horizontal track, aligns position that needs to be connected, and then controller outputs relevant parameters through pipeline package to realize welding of workpiece. Compared with manual steel spot welding, it requires greater welding pressure, higher welding current, and shorter welding time, making design strength of welding gun higher and power of welding transformer greater.
It can realize modular design and maximize the interchangeability of parts
