- Abstract
The dissimilar joints of 16MnR and S31803 were obtained by means of SMAW and GTAW. Hardness of joints has been tested. The results show that hardness distribution from 16MnR base metal to S31803 base metal presents upward trend. Hardness of seam welded by GTAW is higher than seam welded by SMAW. The peak value of hardness appeared in S31803 base metal near fusion line. Peak width of joint welded by SMAW is larger than that of GTAW. The hardness in carbon migration area undergoes a wave process that decrease first, then increase, decrease finally, accompanied by the change of micro-area from base metal to decarburized layer to carbon-enriched layer to welding metal. The fluctuation degree is proportional to heat input.
