BS ISO 23493:2020 pdf free.Welding and allied processes — Process specificationfor laser-arc hybrid welding for metallic materials.
This document outlines the equipment and operator qualification needed for laser-arc hybrid welding,and recommends butt, fillet and flange joint preparations and consumables suitable for use with thisprocess.
lt also gives an overview of the steps to take during equipment set-up, procedure specification,workpiece set-up immediately prior to welding, and after welding once inspecting and testing the welds.This document applies to laser-arc hybrid welding of steels, aluminium and its alloys.
This document does not apply to hybrid processes where laser beam welding is hybridized with anotherwelding process not using an electric arc as its heat source.The following documents are referred to in the text in such a way that some or all of their contentconstitutes requirements of this document.

For the purposes of this document, the terms and definitions given in IS0 15607 and IS0 15614-14 apply.
The welding operator should receive necessary training and education and be competent to his/herjob. An operator of an automated laser-arc hybrid welding process can be qualified through one of thedifferent routes referred to ISO 14732:2013,Clause 4, relevant to automatic welding, namely:
a) qualification based on a welding procedure test in accordance with ISO 15614-14;
b) qualification based on a pre-production welding test in accordance with ISO 15613,ISO 15609-6 and ISO 15614-14;
c) qualification based on a production test or production sample test.
In addition, any method of qualification shall be supplemented by a test of the functional knowledge ofthe welding system, referring to ISO 14732:2013,Annex A.Furthermore, any method of qualification may be supplemented by a discretionary test of knowledgerelated to welding technology, referring to ISO 14732:2013,Annex B.BS ISO 23493 pdf download.
