摘　　要：在碳钢及低合金钢压力容器焊接工艺中,已广泛采用非熔化极(钨极)氩弧焊焊接方法。有色金属与碳钢及低合金钢相比,可焊性较差,焊接难度较大,所以有色金属非熔化极(钨极)氩弧焊焊接工艺还不够成熟。以有色金属(包括铝、铜、镁等及其合金)压力容器焊接为例,通过大量的工程实践证明,从焊接材料、焊接接头型式及尺寸、焊前准备、焊接过程等方面来研究非熔化极氩弧焊焊接工艺,可以使有色金属压力容器焊接接头的焊接质量达到标准要求。In the process of carbon steel or low-alloy non-melt pole（ Tungsten pole） is widely used. Because steel pressure vesselwelding, the argon-arc welding of thenon-ferrous metal is more difficult to be welded than carbon steel and low-alloy steel, this weldingtechnology of non-ferrous metals by non-melt pole （Tungsten pole） argon-arc welding is not developed enough. Takingpressure vesselwelding made of non-ferrous metals （ like Aluminum, Copper, Magnesium and their alloys） for examples, the technologyhas been studied in the fel- low aspects of welding metals, the type and size of welding joint, welding preparation, welding process and so on. A large number of engineering practices show that the improved welding technology can make the quality of non-ferrous metal pressure vessel jointwelding reach the standard requirement.
