All such proposals can be submitted to the designer for approval if necessary. 7.2.3 BUTT WELDS VS. FILLET WELDSsp.info Why do butt welds cause more weld shrinkage?In addition, butt welds tend to have larger volumes of deposited weld metal; this increases weld shrinkage effects and results in higher residual stress levels in the joint. Careful sequencing of welding operations is essential to balance shrinkage and to distribute residual stress, thus minimising distortion .See all results for this question
