需焊接或热切割的表面应排除所有可能会损坏焊材或母材的杂物，如脂、油、灰尘、水垢、熔渣和油漆等。
Surfaces to be welded or thermally cut shall be cleaned of all foreign material such as grease, oil, dirt, scale, slag and paint that would be detrimental to either the weld or base material.
当（螺柱）直接焊于母材时，严禁母材厚度薄于螺柱直径的1/3。
When welding directly to base metal, the base metal shall be no thinner than 1/3 the stud diameter.
它是一种利用焊条与工件之间电弧产生的热量熔化焊条和母材而将被焊工件连接起来的焊接方法。
This welding process joints work pieces by melting the electrode and the base metal with the heat from the electric arc between the electrode and the work piece.
