How to Weld T-1 Steels (1961)

This film details the proper welding procedures for USS T1 steel, a high-strength, versatile metal. It emphasizes three key rules: using the correct low-hydrogen electrodes, applying the appropriate welding heat to ensure rapid cooling, and following specific welding techniques. The video explains how to avoid underbead cracking by using low-hydrogen electrodes and keeping them dry, and how to control heat input using a welding heat input calculator to maintain T1 steel’s toughness. It also covers preferred welding techniques like stringer beads over weave beads, arc air gouging, and methods to prevent shrinkage cracks in fillet welds, such as using more ductile rods, peening, shrink cushions, or butter welds.
