This is the sixth in the series of nine topical reports that detail the research leading to the development of the optimized welding solutions for X100 line pipe steel. Collectively, these reports have highlighted the essential welding variables and the methodology for monitoring and controlling them. In this report, the essential welding variables are examined in greater detail. Initial identification of the primary variables was accomplished using a thermal-microstructural model. The outputs from this model were used in developing a statistical test matrix for welding experiments in flattened...

Collectively, these reports have highlighted the essential welding variables and the methodology for monitoring and controlling them. In this report, the essential welding variables are examined in greater detail. Initial identification of the primary variables was accomplished using a thermal-microstructural model. The outputs from this model were used in developing a statistical test matrix for welding experiments in flattened X100 pipe to validate and corroborate the identification of the primary welding variables.
