The study intended for rational usage of high-strength steel in structure by applying laser-arc hybrid welding has been conducted. Key design requirements and improvement target have been clarified considering their key performances as structural members. The evaluation methods for risk of brittle fracture and cold cracking have been established for quality control. Safety of welded joint has been...
Laser gas metal arc hybrid welding (laser-GMA hybrid welding) offers capabilities for improving the economy of welding in comparison to conventional welding processes due to characteristics concerning material and seam design. Research into this process was restricted to a sheet thickness range of between 6 and 12 mm for steel. However, for steel, container, vehicle or ship engineering in particular,...
