Webthe corner when friction stitch welding was performed in underwater wet conditions, where S355 low-alloy steel was used both as plug and BM [13]. The hardness values of the joints (up to 490 HV 10) were too high to finish the subsequent welding operations well. Drilling for the next weld spot of stitch welding was difficult since (a) feeding the WebThe application of friction welding as a repair procedure to be conducted underwater was ... A process was developed with the intent of providing a method of repair for linear cracks. A sort of stitch welding was employed by which subsequent friction welds of tapered studs (short conical rods) were performed in precise holes to bridge the gap ...
