氩弧焊过去都是在合金钢;不锈钢以及有色金属上使用,而在碳钢上应用很少。 但是随着生产的发展,对工业管道的质量要求愈来愈高,采用手工钨极氩弧焊焊接管道第一层(打底焊),然后用手工电弧焊盖面这对提高管道焊口质量有明显的效果。 目前我公司已在潘家庙天然气接收站到成寿路天然气管线工程、亦庄天然气管线、
TIG welding in the past are all in the alloy steel; stainless steel and non-ferrous metals, and rarely used in the carbon steel. However, with the development of production, the quality requirements of industrial pipes are getting higher and higher. The first layer of the pipeline (base welding) is welded by manual TIG welding, and then the manual arc welding cover is used to improve the welding quality Have obvious effect. At present, our company has been in Panjiaomiao gas station to Cheng Shou Road natural gas pipeline project, Yizhuang natural gas pipeline,
