摘要

The load bearing capacity of pipeline weld joints with varying wall thicknesses and strength mismatch was assessed using finite element analyses. The structural integrity of API X65-API X80, API X42-API X65, and API X42-API X80 weld joints was investigated under tensile, internal pressure and bending load.
