This study shows the effect of the low transformation temperature welding material on residual stress listribution and welding deformation. The expansion due to the transformation fr om austenite to martensite nduces the compressive residual stress around welds. While, in the welding structures, it is important to control the welding deformation and residual stre ss so that they may cause the strength decrease. By using he low temperature transformation welding wire, it may be possible to decrease the weld...
