- 論文の詳細を見る
Pulsed arc welding has superior characteristics with regard to arc statility and refinement of the weld metal micro structure. This investigation was carried out to clarify the influence of low freqency pulsed welding current on solidification cracking susceptibility of SUS 304 and SUS 309 austenitic steel weld metals. It has been established that pulsed welding cursent reduces solidification carking tendency in austenitic steel weld metal. This effect is attributable to the refinement of the columnar solidification structure and a decrease in the segregation levels of sulfur and phosphorus in the weld metals.
