Abstract
Prevention of cracking in weldments is the result of understanding and evaluating extensive experience from cases of damage. The welding process-con trolled mechanics for the initiation of weldment cracking by extensive strain due to thermal expansion of the moving weld pool with its surrounding temperature field, and a local characterisation of the dynamic non-linear behaviour during solidification in, around and behind the weld pool in interaction with the weldment restraint are described in terms of thermo-physical mechanics. Different experience from solidification cracking assessment results in a concept for controlling weldment cracking by means of thermo-physical mechanics.
