概要
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 welding deformation und residual stress f or the cubical expansion. The result of simulation shows that by using the low emperature transformation welding wire, the welding deformation and residual stress could be decreased.
