Abstract

The paper presents a short description and overview of the weld thermal
cycle simulation methods. An experimental investigation on the weld cycle
simulated specimens is predicted by a plan of experiment using single cycle
simulation. The obtained hardness results are compared with double cycle
simulated specimens results of individual points in the heat-affected zone.
Beside that, the characteristic microstructures of points in the heat-affected
zone after a single weld thermal cycle simulation are given. A thermal
simulation method is suitable for different weldability examinations. In
this paper, the authors would like to investigate the maximal hardness of
individual points in the weld joint what is important when considering cold
cracking sensitivity.
