inert gas carbon-arc weld 惰性气体保护碳弧焊接
By comparing backgouging of plasma arc with carbon arc to the welded joint of 13-5 martensitic stainless steel, the backgouging of plasma arc is proved feasible for the full penetration weld.
通过对13 -5型马氏体不锈钢焊接接头进行等离子弧清根及碳弧气刨清根的比较，证明等离子弧清根对全焊透焊缝实施背面清根是可行的。
It was found that impact toughness of weld metal was maximum using carbon arc air gouging, and it was minimum using acid backing.
结果表明，清根方式对焊缝冲击韧度有明显影响，用碳弧气刨清根得到的焊缝冲击韧度最好，而用酸性衬垫得到的焊缝冲击韧度最差。
The method of Carbon arc-welding is adopted. It is feasible in practice to be used in the material weld. The feedback from the user demonstrates the reliability of welding quality.
焊接方法采用碳弧焊，通过生产实践验证是可行的，用户在使用中对产品的反馈论证了其焊接质量的可靠性。
