现阶段,在我国建筑工程施工过程中,应用非常广泛的一种技术焊接技术就是半自动FCAW下向焊接工艺,所谓FCAW,就是药芯焊丝电弧焊,其主要采用的焊接材料是药芯焊丝,不仅性能非常优良,同时还具有其他优势。这种焊法属于自保护焊法或者是熔化极气体保护焊法,在我国建筑工程管道施工中得到了广泛的应用,具有非常好的发展前景。本文主要对建筑工程管道施工中,半自动FCAW具体下向焊接工艺的实际应用进行研究,提出笔者的思考和建议,仅供参考。
At this stage, in China’s construction process, a very wide range of applications is a technology of welding technology is semi-automatic FCAW down welding process, the so-called FCAW, is the flux-cored wire arc welding, the main welding material is flux cored wire, not only Very good performance, but also has other advantages. This welding method is self-shielded welding or welding gas arc welding method, in our construction pipeline construction has been widely used, with very good prospects for development. This article mainly on the construction of pipeline construction, semi-automatic FCAW specific to the actual application of welding technology research, put forward my thoughts and suggestions for reference purposes only.
