Effect of Butt Gap on Stress Distribution and Carrying Capacity of X80 Pipeline Girth Weld

Effect of Butt Gap on Stress Distribution and Carrying Capacity of X80 Pipeline Girth Weld

An unstable assembly gap is detrimental to the formation and performance of the pipeline butt girth weld joint. Therefore, a numerical model of an 18.4 mm-thick X80 pipeline girth weld by a homogeneous body heat source was established to investigate the effect of the butt gap on the joint temperatur...
