Control welding residual stress and distortion is extremely important in manufacturing industry. Double-sided double arc welding (DSDAW), which can control residual stress and angular distortion, is developed. Because arc distance between fore and rear torches is the key effective factor of angular distortions in DSDAW, its effects are not clear on the stress and angular distortions. In this study, numerical simulation is used to predict the transient temperature and welding distortion and stress with different arc distances. Meanwhile, the transient temperature and angular distortion are measured. The calculated results are in good agreement with the experimental results. The effects of arc distance on the angular distortion and stress are investigated. Lower stress and nonangular distortion is obtained at arc distances of 0 mm and 50 mm.
