Abstract
General metal welding occurs distortion. Also, reducing distortion is required much cost. Therefore, the purpose of this study is optimization of welding conditions to reduce distortion in welding of monolithic rack housing for modular steering gear. Firstly, heat source for welding was chosen arc and laser. Secondly, it investigated optimizing welding conditions in bead welding by arc and laser heat source, and welding conditions in fillet welding was optimized with welding shapes. Finally, it was measured temperature distribution of welds by infrared camera and angle distortion in fillet welding. As a result, laser welding was superior to arc welding on distortion.
