不锈钢药芯焊丝熔化极气体保护焊性能对比分析及应用

The Stainless Steel Flux-Cored Arc Welding Comparative Analysis and Application of Welding Performance

药芯焊丝的制造工艺非常精良,随着制造设备的升级,国内市场已经可以提供多种不锈钢药芯焊丝,使用越来越多,范围也越来越广泛;但不锈钢药芯焊丝使用条件、焊接位置等还是存在一定争议,因此对一种不锈钢药芯焊丝选择几个制造商的焊材对比,选择相同试验板材材质、焊接环境、焊接工艺参数进行焊接,之后对力学性能、晶间腐蚀的数据进行对比分析,来阐述不锈钢药芯焊丝的焊接质量和应用方向。另外为了保证焊接质量,不锈钢药芯焊丝要注重运输、储存条件,主要目的是防止焊丝受潮。

With the upgrading of manufacturing equipment,a variety of stainless steel flux-cored can be provided in the domestic market,which is used more and more widely;However,there are still some disputes about the service conditions and welding position of stainless steel flux-cored.Therefore,for a stainless steel flux-cored,select the welding materials of several manufacturers,select the same test plate material,welding environment and welding process parameters for welding,and then compare and analyze the data of mechanical properties and intergranular corrosion.This paper expounds the welding quality and application direction of stainless steel flux-cored.In addition,in order to ensure the welding quality,the stainless steel flux-cored should pay attention to the transportation and storage conditions,and the main purpose is to prevent the wire from being damp.
