For not-fully-penetrated butt welds, types of joint preparation and dimensions 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 Stadard 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.
