Effect of grooves on the static strength of tubular T joints of offshore jacket structures

Forming Control Method of Single‐Layer Multi‐Pass Welding in the Intersection for T/K/Y Joints of Jacket

“…However, the groove size on the jacket is large, and the cost of machining grooves with high precision is too high. [ 7 ] Only flame cutting can be used, which limits the machining accuracy, and makes the production method highly discrete and working conditions worse. Furthermore, it was filling amount varied with the welding position that the complex shape and inconsistent width on each part of the offshore jacket groove require.…”
