Of these welding-induced quantities often manifest themselves on a structural level, such as crack development with no appreciable global structural load as a result of residual stresses. SYSWELD is a commercially-available FEA software package developed by ESI Group.

However, cold cracking is an increasing problem concerning the weldability of these materials. For the prediction of cold cracking susceptibility many different tests exist. The most important ones are the Tekken‐(Y‐groove restraint test), the controlled‐thermal‐severity test (CTS) and the implant test. But in spite of the same or similar welding conditions, one gets different minimum preheat temperatures dependent on the used test procedure. Therefore, a better evaluation of these tests seems to be necessary. Based on the commercial FEA‐tool SYSWELD three main factors influencing cold cracking were investigated for MAG‐welded Tekken specimens: the distribution of microstructure, the stress‐strain state and the hydrogen concentration.

The analysis was performed for S690 low alloy high‐strength steel. Also, welding experiments were carried out to determine temperature field and microstructure.
