Everyone knows that the production of welding machine is very strict. In order to ensure the quality of the welding machine equipment, we must pay attention to the fluidity of the liquid in the production. The fluidity of the liquid is large, which will cause improper operation and will cause the solution to enter the gap. , causing slag inclusions, affecting continuous welding. It is even more important that the welding machine is finished at the end of the finishing work. In the finishing operation of the welding machine equipment, it is necessary to pay attention to the need to leave a deep crater on the surface of the weld, in addition to the damage to the internal structure.
In the end of the welding machine equipment, the arc should be shortened, the welding speed should be accelerated, and the swing range should be paid attention to, and the swing range is narrowed. After reaching the end point, the welding manipulator stops moving forward, the arc extinguishes the arc, and the molten pool is slightly condensed before the arc welding wire is reached. After the molten pool is filled, the welding torch is quickly lifted. If the arc is broken prematurely, the liquid metal solidifies quickly. The gas can't run out, leaving holes in the weld, which will cause craters on the surface.
Because the weldment material or the weldment is not the same size, the welding machine is not the same at the end of the welding process.
