The ground wire used shall be in a proper position and connected firmly to avoid arc burn on the surface or excessive burn area; during welding, it shall take measures to prevent splashing.

焊接后当清理焊渣时应用不锈钢扁铲,不得用碳钢类扁铲。焊缝处它应认真修磨,使焊缝与母材表面光滑过渡,不得有熔渣、气孔、咬边、飞溅物、裂纹、未熔合等质量缺陷。

After welding, when cleaning welding slag, stainless steel flat shovel shall be used instead of carbon steel flat shovel. The weld joint shall be carefully polished to make the smooth transition between the weld joint and the base metal surface, and there shall be no slag, air hole, undercut, spatter, crack, incomplete fusion and other quality defects.
