Property Study on Shearer Picks Brazed by Water Soluble Copper Brazing Agent
By using HL105 brazing piece as filler metal and the water soluble copper brazing agent made by self, the coal cutter was welded by induction brazing. 42CrMo steel can be used as body and YG15 hard alloy can be used as head. By studying the microstructure and mechanical property of brazing seam, the bending strength of the welded joint was welded by using home-made fluxes,which has achieve a superior level. The quality of the brazing seam on the condition of the fluxes and water in a four-to-six ratio is superior, when the fluxe is dewatering borax or the fluxes and water in a half-to-half ratio. The longevity of shearer picks welded by water soluble copper brazing agent made by self improves largely. The pieks produced by new process is larger market.
