不锈钢管道在工业设施中是经常用到的,由于不锈钢的特性在使用常规氩弧焊焊接中管内必须进行充氩保护,不然内部表层极容易被氧化从而影响焊接质量。这样一来对管道的焊接速度及成本都带来极大的影响,特别是系统复杂的管路将造成大量保护氩气的使用和浪费。根据现场施工的实际情况及以往施工的经验,采用一种不向不锈钢管内充氩保护的焊接方法,既可以节省保护用氩气的消耗,又能减少焊接成本的支出,还能保证管道焊缝的质量。
Stainless steel pipe is often used in industrial facilities. Due to the characteristics of stainless steel, it is necessary to carry out argon filling protection in the pipe when using conventional argon arc welding. Otherwise, the internal surface layer is easily oxidized to affect the welding quality. This will have a tremendous impact on the welding speed and cost of the pipeline, especially the complex system of piping will cause a lot of protection and use of argon gas waste. According to the actual situation of the construction site and the past experience in construction, using a stainless steel tube is not argon protection of the welding method, which can save the protection of argon consumption, but also reduce the cost of welding costs, but also to ensure that the pipe weld the quality of.
