T1 - Properties and weldability of modified low transformation termperature filler wires N2 - Low transformation temperature (LTT) alloys allow to control residual stresses already during the welding process. Especially high-strength structural steel applications may benefit from the LTT effect as they are sensitive to residual stresses due to a limited ductility. Within this study, two modified LTT alloys were tested concerning their weldability under varying conditions. Beside the transformation behavior, basic material properties were determined from all weld metal. Hot cracking as well as cold cracking susceptibility was evaluated using specific tests. The materials' capability for residual stress control was characterized by online measurements of the occurring loads during double-sided multipass fillet welding in a special test facility. Varying heat control parameters were found to affect the stress buildup significantly. In the specific case, the results revealed that higher working temperatures may favor lower stress buildup despite the higher overall heat input. Local residual stress measurements using X-ray diffraction support this finding.
