Abstract

erosion behavior and microstructure of the weld metal in the HSLA-100 steel joints were studies. The Welding of the alloy carried out by GTAW method with electromagnetic vibration simultaneously. The microstructure investigations were done by optical and SEM microscopy. Erosion test with slurry(water+5% sand) at the time from 0. 5 to 2 hours, 10 ms-1 speed, impact angles 30, 90 was carried out. The results shows that by applying electromagnetic vibration the microstructure shifts from Quasi polygonal ferrite with austnaite-martensite (M A) coarse and coadunate islands to the acicular ferrite with the finer and more uniform distribution M A islands. It was revealed that the electromagnetic vibration causes improving the erosion behavior in the both impact angles, especially 90 degree. The best erosion behavior (lower erosion rate and least weight drop) of weld metal was obtained under vibration of 30 volts. The erosion dominate mechanism were recognized plowing and plastic deformation, forming and separating of the metallic particle, for 30 and 90 angles, respectively.
