PROCEDURE:
焊接工艺：

Prepare joint area by removing foreign material. Bevel heavy sections to form a 90° vee. Hardenable alloys should be preheated. Use jigs, fixtures and tack welds to maintain alignment. Hold a short arc. Stringer beads are preferred to prevent overheating. Allow to cool before removing slag. Deposits will take a high polish when subjected to wear.

通过清除异物来准备接合区域。斜切厚截面部分，形成90°V形。可硬化合金应预热。使用钻模、夹具和定位焊缝保持对齐。保持短弧。为了防止过热，推荐使用线状焊道。在清除熔渣之前，让其冷却。沉淀物在磨损时需要高度抛光。
