Abstract

Narrow gap welding (NGW), which is effective in reducing heat input and achieving high productivity, is often employed in thick wall welding. However, for NGW, when the welding condition is not correctly selected, pear-shaped bead cracking will occur. The groove parameters have a significant influence on pear-shaped bead cracking. In this research, the effects of groove parameters on pear-shaped bead cracking and effective penetration depth are analyzed in detail by using FEM employing a temperature dependent interface element. Then, the welding condition is optimized for different groove parameters to achieve maximum effective penetration depth and maximum effective penetration depth per unit heat input, but without cracking.
