在有关焊接制造行业中,各大中型企业的焊接机械化和自动化程度相对较高,不过,在国际上对焊接机械化和自动化相比还有较大的提升空间。焊接机械化是指焊接机头的运动和焊丝的给送由机械完成,焊接过程中焊头相对于接缝中心位置和焊丝离焊缝表面的距离仍须由焊接操作工监视和手工调整。 In the welding manufacturing industry, large and medium-sized enterprises have a relatively high degree of mechanization and automation of welding. However, there is still much room for improvement in welding mechanization and automation in the world. Welding mechanization means the movement of the welding head and the feeding of the welding wire are done by the machine. The welding head position relative to the joint and the distance of the welding wire from the welding surface still need to be monitored and manually adjusted by the welding operator.
