In a previous paper, we have shown the effect of welding conditions on welding deformations in bead-on-plate test. In the present report, we deal with the effect of welding conditions on welding deformations in multipass welded butt joint.
The results obtained in this report are summarized as follows:
(1) Welding deformations in multipass welded butt joint are derived by the use of conventional formulae of welding deformations in bead-on-plate test.
(2) Effect of welding process on welding deformations in multipass welded butt joint depends on specific deposited heat.
(3) Welding deformations in multipass welded butt joint are decided from total number of beads N, which is functions of thickness, heat input, bevel angle, density of wire and specific deposited heat.
