Alcance
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.
