International organizations, governmental and non- governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Elect

INTERNATIONAL STANDARD 0 IS0 IS0 9692-2: 1998( E) Welding and allied processes - Joint preparation - Part 2: Submerged arc welding of steels 1 Scope This part of IS0 9692 applies to types of joint preparation for submerged arc welding with one wire electrode (process 12

18、1 according to IS0 4063) on steel. This part of IS0 9692 covers only the welding positions PA and PB according to IS0 6947. In case PC is used, special preparation will be necessary. It applies to fully penetrated welds. For partly penetrated welds, types of joint preparation, shapes and dimensions

19、may differ from the listed proposals if they are specified in the relevant application standard or agreed by parties concerned. If the root is welded by a different arc welding process (see IS0 40631, the joint preparation according to IS0 9692 should be taken into account. 2 Normative references Th
