Embodiment Construction
[0015] The embodiment provided by the present invention is described in further detail:
[0016] A kind of argon arc welding process of T-shaped steel, described T-shaped steel is 16Mn, comprises the following steps:
[0017] (1) Processing of weldments and selection of welding materials
[0018] First, remove the dirt on the surface of the parts to be welded to ensure the dryness of the welded parts;
[0019] Second, the selection of welding materials, the selection of welding wire;
[0020] (2) Temporary spot welding
[0021] First, argon arc welding is used for temporary spot welding, the welding current is 160-200A, the welding voltage is 20-24V, and the length of spot welding is 10-100mm;
[0022] Second, pay attention to temporary spot welding. The height and width of temporary spot welding must not exceed the size of the future weld. It should be a part of the future weld. The arc crater should be filled. Spot welding on the back side. After the front side is welded...
