焊接和相关工艺 接头准备型式 第1部分 手工金属电弧焊,气体保护金属电弧焊和气焊, 钢的钨极惰性气体保护电弧焊和镭射光焊接

[中文适用范围]： ISO 9692 的本部分规定了钢的手工金属电弧焊、气体保护金属电弧焊、气焊、TIG 焊和束焊的接头准备类型。 [外文原描述]： ISO 9692-1:2013 specifies types of joint preparation for metal arc welding with covered electrode, gas-shielded metal arc welding, gas welding, TIG welding, and beam welding of steel. It applies to joint preparation for full penetration butt welds and for fillet welds. For partial penetration butt welds, types of joint preparation and dimensions differing from those specified in ISO 9692-1:2013 may be stipulated. The root gaps referred to in ISO 9692-1:2013 are those gaps presented after tack welding, if used. Consideration is given to altering the joint preparation details (where appropriate) to facilitate temporary backing, "one-sided welding," etc.
