• Distribution of Ferrite in the Austenitic Stainless Steel Weld Deposit

抄録

As to the austenitic stainless steel deposited metals by the covered arc welding and band arc welding, investigation has been made about influence of the arc voltage on ferrite content and distribution of ferrite in the bead. In case of the cavered arc welding, FN in the deposited metals has sharply dropped when the arc length is lengthened. This main cause is lowered Cr content in the deposited metals due to oxidization and remarkably increased N content on account of absorption of O and N in the air caused by the arc length increased. In case of the band arc welding, no change in N content has been found by the arc voltage increased.<BR>FN in the bead section produced by the covered arc welding has a distribution from, higher at the section center and lower at the bead surface and in the neighborhood of weld bond. FN of the bead section produced by the band arc welding has shown somewhat complicated distribution. As the results of analyzing these sections by means of EPMA, a density gradient of Cr corresponding to the change of FN has been noticed.
