Embodiment Construction
[0024] A welding process for steel plates, characterized in that it comprises the following steps:
[0025] (1) Preparation before welding:
[0026] First, remove all the accumulated water and snow on the surface of the weldment to ensure that the surface of the weldment is dry;
[0027] Second, remove the dirt on the surface of the parts to be welded, such as lumps of rust oxides, oil, etc.;
[0028] Third, the welding method and the selection of welding materials, the melting electrode CO2+Ar gas shielded welding is used for welding, and the welding wire of H08Mn2SiA steel grade;
[0029] (2) Temporary spot welding:
[0030] First, according to the size of the welded structural parts, the length of spot welding is selected as 60mm;
[0031] Second, pay attention to 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. Back spot welding, when the front side is welded, the...
