Friction Stir Welding of Steel for Pipeline Fabrication
Friction Stir Welding of Steel for Pipeline Fabrication
Friction stir welding procedure development was initiated on steel grades S460 G2+M and S690QL1 in plate wall thicknesses of 10 and 15mm. To tackle the challenges of the high mechanical loads on the tool as well as its premature wear, a combination of preheating and optimized weld backing set-up was implemented. The inductive preheating allowed a...
