Course WCS-1 The Weldability of Carbon Steels
Duration: 1 Day
Click for Terms and Conditions
Course overview:The welding of different
types of carbon 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 steels
and provides course members with a firm understanding
of the controls required.
Course content: Review of steel types;
manufacture of 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; combined thickness; Carbon equivalents;
need for pre-heat; welding techniques; cracking in
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 carbon steels types and their weldability
Course outcomes:
On completion of the course you will be able to:
- Understand the different types of steels available
and their general weldability problems.
- Understand the different ways in which steels are
produced and the effects on weldability.
- Derive appropriate pre-heat/heat inputs for a given
application.
- Appreciate the factors that influence welding process
and welding consumable selection.
- Understand why welds may crack and how such problems
can be avoided
- Understand weldability concepts including CE, heat
input control, pre-heat, post weld heat treatments & other
factors.
