Effect of Welding Conditions on Reduction of Angular Distortion by In-Process Control Welding using Back Heating Source
In order to investigate the effect of welding conditions on reduction of angular distortion by in-process control welding using back heating source, numerical analysis is done. Furthermore, positional condition setting of back heating source and required back heat input for complete control of residual angular distortion are discussed. These results show that in-process control welding by back heating immediately behind of welding torch can be extremely effective to reduce angular distortion.
