Course WSS-1 The
Weldability of Stainless Steels
Duration: 1 day
Click for Terms and Conditions
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:
On completion of the course you will be able to:
- Understand the different types of stainless steels
available and their general weldability problems.
- Understand the different ways in which stainless
steels are produced and the effects on weldability.
- Derive appropriate welding data for a given application.
- Appreciate the factors that influence welding process
and welding consumable selection.
- Understand why welds may crack or corrode and how
such problems can be avoided
- Understand different weldability concepts.
