Recommendations for joint preparation —Part 3: Metal inert gas welding and tungsten inertgas welding of aluminium and its alloys.
This part of ISO 9692 specifies types of joint preparation for metal inert gas welding, MIG, (131) and tungsten inert gas welding, TIG, (141) on aluminium and its alloys.
It applies to fully penetrated welds.

3 Materials
Joint preparations recommended in this part of ISO 9692 are suitable for all types of aluminium and its weldable alloys.
4 Welding processes
Joint preparations recommended in this part of ISO 9692 are suitable for welding carried out in accordance with the following processes as specified in Tables 1 to 3. Combinations of different processes are possible:
metal inert gas welding (MIG) (131)
tungsten inert gas welding (TIG) (141)
NOTE The numbers in pararitheses refer to the reference number of the welding process specified in ISO 4063.
5 Finish
Edges should be prepared by mechanical means (e.g. shearing, sawing or milling). No cleaning fluids based on mineral oil shall be used, If plasma cutting is used, consideration shall be given to the quality of Cut surfaces (e.g. cracks).
The longitudinal edges of the root face should be de-burred and chamfered, especially for single sided butt welds without backing.
6 Type of joint preparation
The recommended types of joint preparation and dimensions are specified in Tables 1 to 3.
The choice of joint details (angle, gap, thickness of root face) depends on the joint thickness, the position and the
welding process. The use of larger gaps ( 1,5 mm) permits smaller angles.
If gaps are 1,5 mm, backing is preferably used.
For single sided welding, backing bars should be grooved.
NOTE The reference numbers have been determined in accordance with the following scheme:
The first digit corresponds with the number of the table (e.g. digit 1 for Table 1 with joint preparation for butt welds, welded from one side), the second digit or numerical group corresponds with the number in ISO 2553 (e.g. git 2 for square butt weld as given in Table 1 of ISO 2553:1992), the third indication, expressed by a letter, covers the variants of joint preparations.
EXAMPLE Joint preparation for a butt weld, welded from one side (1), finished for single-V butt weld (3) gets the number:1.3.
