Joining 30 mm Thick Shipbuilding Steel Plates EH36 Using a Process Combination of Hybrid Laser Arc Welding and Submerged Arc Welding

, 2022
This article presents a cost-effective and reliable method for welding 30 mm thick sheets of shipbuilding steel EH36. The method proposes to perform butt welding in a two-run technique using hybrid laser arc welding (HLAW) and submerged arc welding (SAW).

The analysis of shielding gases in laser–arc hybrid welding processes

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2011
Acceptable quality laser–arc hybrid welds can be produced with many different process gas compositions, but if the objective is high productivity, low gas costs, a reliable process, and the best quality, the shielding gas composition makes a remarkable difference in the laser–arc hybrid welding of steels.

Direct Metal Deposition of Graphene–Ti28Nb35.4Zr Matrix Composites With Enhanced Mechanical, Corrosion, and Biocompatibility Properties for Bone Implants

Advanced Engineering Materials, Volume 28, Issue 13, 8 July 2026.
Graphene nanoplatelet (0.1 wt.%) reinforcement significantly enhances the performance of β Ti‐28Nb‐35.4Zr alloy. Grain refinement, reduced water contact angle, and improved surface characteristics promote osteoblast adhesion and complete surface coverage after 7 days.

Effects of edge oxides from laser cutting in laser-arc hybrid welding

, 2018
Laser-arc hybrid welding (LAHW) is a promising technique for joining sheets due to fast processing speeds and small gap bridgeability. Prior to welding, the edges are often prepared using laser cutting.
