Materials Weldability - Stainless Steels

Suitable for:

Engineering staff involved with design, specification, fabrication, inspection or application of stainless steel materials.

Course Content:

Basic metallurgy and properties of stainless steel; corrosion and oxidation resistance; weldability of highly corrosion resistant grades (duplex, super duplex and high alloy austenitics); weldability of conventional stainless steels (austenitic, ferritic and martensitic); avoidance of weld defects; use of Schaeffler diagram for dissimilar joints; measurements of ferrite levels and ferrite number (FN); weld overlaying and welding clad steels; degradation of stainless steels (pitting, crevice corrosion and stress corrosion cracking); practical considerations for welding stainless steels.

Objectives:

• to appreciate the influence of composition on stainless steel properties
• to understand various weldability problems of different grades
• to identify welding conditions necessary to achieve optimum weld area corrosion resistance
• to recognise how stainless steel corrosion resistance can be degraded
• to apply knowledge to welding of dissimilar joints and weld overlays
• to appreciate practical implications of welding stainless steels.
