NOTE Qualification of seal welds made in the factory is not covered in this annex. NOTE 1 The dimensional limitations of flaws subject to rejection specified in The location, elements to be analysed and acceptance criteria should be approved by the employer [see 4.

Arc welding of aluminium and aluminium alloys. Dye penetrant testing should be carried out in accordance with BS EN Where more than one process or welder is utilized in producing a complete welded joint, the successful testing of the completed weld shall qualify each welder for his respective portion.

Under no circumstances shall a welder be employed on operations other than those for which they have been 44515-2, qualified and approved. When a time lapse is specified, then the definition of the start and completion of runs should be stated.

It presents the UK view on standards in Europe and at the international level.

Number of welders for second run: Specification pour la soudure des canalisations en acire sur la terre et en mer. Tack 45155-2 shall be used only in accordance with NOTE Welds should be separated by the maximum possible distance.

The following tests should be performed on the sections.

Qualification testing of welders for under-water welding. The mechanical strength of the joint should be tested by means of a sharp blow from a 1 kg hammer.

NOTE The mechanical properties of the plate used may differ from the parent metal of the pipe specified in the welding procedure at the discretion of the employer.

Gases shall only be mixed in the field if this is an integral part of a mechanized process which utilizes a fail-safe cut-off when the proportions fall outside those specified in the approved welding procedure.

X-ray exposure and the use of BS EN The test weld to qualify a partial penetration repair weld procedure should be made into an excavation with a remaining ligament not larger than that to be used in production. All welding and tests should be witnessed by the employer. NOTE In view of the additional difficulty involved in making a joint at the intersection of two pipes not at right angles, for branch pipes sloping away from a main pipe consideration should be given to using a right angle branch and a bend to give the required slope.

For MMA welding with cellulosic electrodes Maximum time lapse between start of root run and start of second run: Fillet welds shall always be subjected to destructive testing. D If all weld metal tensile testing was required for the original welding procedure see 8.
