钨极氩弧焊是在普通氩弧焊基础上发展起来的一种焊接工艺 ,由于采用了可控的脉冲电流取代了连续电流 ,因此它特别适用于一些热敏感的金属材料薄板、超薄板构件 ,也用于薄壁管子的全位置焊接等。本文利用扫描电子显微镜研究了薄板液压支柱中的 0Cr13不锈钢板衬里焊接参数的基值 TIG welding is a welding process developed on the basis of ordinary TIG welding. Due to its controllable pulse current instead of continuous current, it is especially suitable for some heat-sensitive metal sheets, Components, also used for thin-walled pipe welding and other full position. In this paper, scanning electron microscopy was used to study the basis of welding parameters of 0Cr13 stainless steel plate lining hydraulic prop
