摘要: Abstract This paper focuses on high power fiber laser welding of steel material for the field pipe production. X65 and X70 plate in thicknesses 9.5 mm 14 mm was welded with laser-GMA-hybrid processes a maximum 8 kW. Two different filler wires joint preparations were tested their weldability. Relating to these procedures thicknesses, characterisation samples such as hardness, tensile testing Charpy V-notch carried out results will be reported this paper.
