it offers including better energy coupling, higher welding speed, and thicker-section welding capability. However, the conduction mode is often preferred for welding aluminium thin sheet because of its... examination Prior to the macrostructure and microstructural examinations, the transversely cross-sectioned weld samples were cleaned, ground and polished to 1 μm surface finish. Thereafter, the polished......
