Course overview:The welding of different types of the various stainless steels requires a number of considerations to be assessed in order that the finished weld satisfies its intended purpose. This course looks at various topics related to the welding of a range of stainless steels and provides course members with a firm understanding of the controls required.
Course content: Review of stainless steel types; martensitic, ferritic, austenitic, PH, Duplex stainless steels; achievement of mechanical and metallurgical properties; structure of the welded joint; heat affected zone metallurgy; weld metal metallurgy; welding process selection; welding consumable selection; heat input control; Cr-Ni equivalents; Schaeffler and Delong diagrams; welding techniques; cracking and corrosion in stainless steels – causes and avoidance.
Suitable for: Non-welding personnel including Engineers who are required to appreciate weldability problems and solutions. Also suitable for welding inspectors, welding engineers and welding supervisors who are required to understand the technical considerations of different stainless steels types and their weldability
Course outcomes:
