This document specifies requirements that are particular to stud welding, in relation to welding knowledge, quality requirements, welding procedure specification, welding procedure qualification, qualification testing of operators and testing of production welds. This document is applicable where it is necessary to demonstrate the capability of a manufacturer to produce welded construction of a specified quality. NOTE General quality requirements for fusion welding of metallic materials are given in ISO 3834-1, ISO 3834-2, ISO 3834-3, ISO 3834-4 and ISO 3834-5. This document has been prepared in a comprehensive manner, with a view to it being used as a reference in contracts. The requirements contained within it can be adopted in full, or partially, if certain requirements are not relevant to a particular construction (see Annex A). For the working range of stud welding, see Annex B.

This document specifies the general requirements and tests for decomposition blockers downstream of pressure regulators in acetylene manifold systems (see ISO 14114). Decomposition blockers can be used in the low-pressure section (downstream of acetylene manifold system outlet) up to 0,15 MPa (1,5 bar) e.g. in pipelines, outlet points or for the protection of low-pressure sections in big pipe systems. Decomposition blockers can only be used in sections with pure acetylene. The possible backflow of oxygen or air into the section where the decomposition blocker is installed needs to be prevented by a non-return valve downstream of the decomposition blocker.
