Taking the following current weldig methods as examples which are SMAW,SAW,GTAW and GMAW,this paper make a comparison to the full penetration weld for the small diameter steel drum from the productivity,the labor intensity,the economic benefits and so on.
以焊条电弧焊(SMAW)、埋弧焊(SAW)、钨极气体保护焊(GTAW)和熔化极气体保护焊(GMAW)四种通用焊接方法为例,从生产率、实现焊接质量的难度、劳动强度、技术先进性和经济效益等方面对小直径钢筒体的全熔透焊缝进行了比较。
