Through the process test of CO2 gas shielded welding and welding boom
the penetration
hardness and mechanical properties of the specimen were tested. The test results show that controlling the welding parameters can ensure the weld quality of CO2 gas shielded welding and meet the quality requirements of the boom products. Compared with CO2 gas shielded welding
the welding of arc welding seams is beautiful and the welding efficiency is greatly improved.
