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.
