Abstract
Criteria for evaluation of sensitivity to hot and cold cracking by different methods applied to determine technological strength were considered. Dependence of the sensitivity of material to cracking on its degradation was evaluated by the Varestraint-Test method. It is shown that cracking in all cases is caused by degradation of the material in certain temperature conditions and stress-strain state.
Keywords: weldability, degradation, thermal stress, hot cracks, cold cracks, technological strength, test methods, brittle temperature range
