Daftar Isi:
- Residual stresses exist in the solid materials that has previously been subjected to non uniform temperature changes. Residual stresses in welded cast iron can cause serious problems such as hydrogen-induced cracking and stress corrosion cracking. Post weld heat treatment is often used to reduce residual stresses in weldments. In the research, material was used welded cast iron that has heated at 150°C , 300°C , 450°C and 600°C , and then made speciments for tensile and hardness testing. The results of this research show that post weld heat treatment can increase tensile stress but decrease hardness of welded cast iron.
