Abstract

With self-developed pulse weld device, stainless steel 1Cr18Ni9Ti is pulse welding repaired under three different conditions. Metallographic specimens are prepared respectively. Metallographic observation results show that the size of pores in the fusion zone and the pulse weld layer increases along with thickness of the patches. Crystal grains in fusion zone are cellular and thick, while the crystal grains of pulse weld layer are mostly thin and long cellular or columnar dendrites, and the direction of the crystal grains grows almost perpendicular to the pulse weld surface. The matrix metal which is a bit far from fusion area presents no significant structural change.
