Abstract
This document reports on research to assess the weldability of a range of high-strength (X80 grade) line pipe steels using both small-scale weldability trials, the Welding Institute of Canada test, and full-scale girth welds. Hardness and tensile tests were used to assess strength, and Charpy V and crack tip opening displacement tests were used to assess toughness. Experimental results are provided and a number of conclusions are listed.
