适用范围: This International Standard pertains to types of joint preparation for metal-arc welding with covered electrode, gas-shielded metal-arc welding and gas welding on steel (see clauses 3 and 4). It applies to joint preparation for fully-penetrated bult welds, except in the case of some rec-ommended types of joint preparation (reference numbers 3.10A, 3.10B and 4.10.10C); if a butt weld is not possible or necessary, special arrangements need to be made. For not-fully-penetrated butt welds, types of joint preparation and dimensions differing from those specified in this International Standard may be stipulated. The root gaps referred to in this International Stan-dard are those gaps presented after tack welding, if used. Consideration should be given to altering the joint preparation details (where appropriate) to facilitate temporary backing, "one-sided welding", etc.
