In addition, the welding quality of welding robots is greatly affected by the welding wire. Avoid choosing low-quality copper plated welding wire, otherwise it is easy to produce welding impurities. These impurities are actually impurities in the welding wire and welding substrate of the welding robot, mainly the high-temperature oxidation of silicon and manganese during the welding process, as well as the chemical reaction of CO2 in the protective gas, which is also the main reason affecting the welding quality of the welding robot.
