Traditional metal frame welding mainly relies on manual operation. However, manual welding has many disadvantages. On the one hand, the quality of manual welding depends largely on the technical level and working status of the welder, and the welding quality is unstable. Differences in welding techniques and experience of different welders may lead to large differences in the appearance and strength of the weld. On the other hand, manual welding has high labor intensity, poor working environment, and long-term welding operations are likely to cause damage to the health of welders. Moreover, manual welding efficiency is low and it is difficult to meet the needs of large-scale production. With the advancement of science and technology, automation technology has gradually been applied to the field of metal frame welding. Automated welding devices can achieve high-precision and high-speed welding operations, effectively improving welding quality and production efficiency.
