1·This paper briefly introduces the work principle and structure of carbon arc air gouging.

介绍了碳弧气刨的工作原理和组成结构。

2·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。

3·The developed welding power source ZX5-800Dshows a satisfactory performance in the welding process of TIG. Shield metal arc, submerged arc and the. carbon arc air gouging.

研制的ZX5一800D电源在进行钨极氩弧焊、手工电弧焊、碳弧气刨及埋弧焊时均获得满意的性能。

4·It can provide several high performance welding modes, such as constant-voltage submerged arc welding, constant-current submerged arc welding, gas shielded welding and carbon arc air gouging.
