Welding of Modern High Strength Steels

The most important weldability aspects of modern,thermomechanically processed, low-alloy high strength steels are discussed in the following presentation.The specific problems considered are the higher hardenability of these clean steels,low toughness connected with local brittle zones in the heat affected zone,softened zone in the heat affected zone, and toughness of a weld metal at high heat inputs.
