自动化焊接薄壁容器时,在纵焊缝的两端容易出现未熔合现象,需要补焊,部分容器报废,给企业生产造成一些经济损失。本文在分析缺陷产生原因的基础上,采取一些措施:如合理调整焊接工艺参数;焊接设备的维修和保养,定期更换导电嘴和清理焊枪内的熔渣;对控制系统的部分功能进行扩展,减少了焊接缺陷。 Automated welding of thin-walled containers, longitudinal welds at both ends prone to unmelted phenomenon, the need for welding, some containers scrapped, resulting in some economic losses to the production of enterprises. Based on the analysis of the causes of the defects, this paper takes some measures: such as adjusting the parameters of the welding process reasonably; repairing and maintaining the welding equipment, regularly changing the contact tips and cleaning the slag in the welding torch; expanding some functions of the control system to reduce The welding defects.
