In every segment of the welding industry there has been a growing trend to replace shielded metal arc welding (SMAW) with semi-mechanized processes such as gas metal arc (GMAW) and flux cored arc welding (FCAW). Flux cored wire welding has potential applications in making pipeline girth welds. The objectives of the program were to obtain data on the toughness and the resistance to hydrogen cracking of three flux cored weld metals using standardized tests enabling comparisons with existing data for shielded metal arc weld metal. The three consumables were selected in discussion with the Welding...
In every segment of the welding industry there has been a growing trend to replace shielded metal arc welding (SMAW) with semi-mechanized processes such as gas metal arc (GMAW) and flux cored arc welding (FCAW). Flux cored wire welding has potential applications in making pipeline girth welds. The objectives of the program were to obtain data on the toughness and the resistance to hydrogen cracking of three flux cored weld metals using standardized tests enabling comparisons with existing data for shielded metal arc weld metal. The three consumables were selected in discussion with the Welding Supervisory Committee and included two gas shielded wires and one self-shielding system.
