Abstract : A method of welding two HY-steel members to produce a weld joint having improved impact toughness. The surface to be welded are first machined, roto blasted and cleaned with acetone. Then, an insert of Inconel 600 is provided and cleaned with acetone. Next, the Inconel 600 insert is introduced between the surfaces to be welded and the HY-steel members are butted against the insert. Then, a laser welding beam is applied to the Inconel 600 insert to weld together the assembly of steel members and insert.
