Horizontal welding quality control of the CO2 gas shielded welding
Jiangsu Province Xuzhou Technician Institute, Xuzhou 221151, China
In the process of horizontal butt welding of CO2 gas shielded welding, the molten metal will squat under the effect of its own weight. Therefore, the upper part of the weld seam is very easy to produce undercuts, and the lower part is prone to defects such as welding and unwelding. If the problem is serious, it will cause welding. Seam cannot pass the weld quality test. This article is based on the welding skill training topic “CO2 gas shielded welding transverse welding”. Through trial and error of preparations before welding, selection of welding process parameters, and welding operation process, Weld seam quality is well controlled, weld seams are beautifully formed, and relevant experience is promoted in practical training.
