BS ISO 23493:2020 pdf free.Welding and allied processes一Process specification for laser-arc hybrid welding for metallic materials.
BS ISO 23493 1 Scope 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 this process.It 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 another welding process not using an electric arc as its heat source.

Then, check the joint fit-up (gap and hi/lo mismatch) to ensure this is within the requirements of the WPS. Adjust the fixture until the fit-up between the work pieces is acceptable.Finally, apply any additional material cleaning required to those parts of the joint still accessible.
