本文介绍了一种小车式双丝窄间隙气体保护焊机,在研制的过程中,重点解决了导电杆和导电咀、气体保护罩的结构;焊缝跟踪,导电杆浮动以保持杆伸长恒定等技术问题。
In this paper, a kind of car-type double-wire narrow-gap gas shielded welding machine is introduced. During the development of the welding machine, the structure of the conductive rod, the conductive nozzle and the gas shroud is mainly solved. The welding seam is tracked and the conductive rod is floated to keep the rod elongation constant And other technical issues.
