Improved Development on Electrode Formula of D608
Electrode D608 is prone to pore, slag eye, sonim, crack and misrun etc. in the Welding process , through improving formula of electrode D608 to enhance its welding performance. Joining a small amount of tungsten, ferromolybdenum, ferroboron and sepiolite etc materials in electrode formula of D608, wiping off graphite, white clay and aluminite powder, also reducing usage amount of ferrosilicon, obtaining a bran-new electrode formula X-D608, which also make an analysis of welding performance and welding organization for new electrode in grey cast iron, finding that welding seam structure of new formula electrode became thinner, pores, cracks and other defects significantly reduced.
