Abstract: Metallographic studies of the high-strength, low-alloy steels weld metal structure show that the cracks in the structure can pass through several grains, or stop at the grain boundary or in the middle of the grain. Resistance to weld metal brittle fracture is usually associated with the grain size in its structure. Recently, works have appeared in ... Show More
