Optimization of Multi-Wire GMAW Welding Procedure for Heavy-Wall Offshore Pipeline Construction

The proposed work will perform research for the optimization of welding processes for heavy-wall applications, address key technological issues in multi-wire gas metal arc welding (GMAW) processes, and fill important gaps in welding practice for offshore pipeline construction. The objectives are to 1) conduct quality evaluation of girth welds made with multi-wire GMAW processes, 2) establish correlations between welding conditions and girth weld properties, and 3) assist the implementation of new knowledge base and guideline for welding practice in offshore high-strength pipeline construction.
