Suitability of heat treatment for crack resistance of material in the connection part of heavy transporter for liquid slag

The post weld heat treatment (PWHT) was used to reduce the level of the residual stresses and increase of the crack resistance of the material in the connection part. The article presents the results of the residual stress measurements immediately after welding and after the stress relaxation by the PWHT.
