Course WAA-1 The Weldability of Aluminium Alloys
Duration: 1 day
Click for Terms and Conditions
Course overview:The welding of different
types of the various aluminium grades 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 aluminium alloys and provides course
members with a firm understanding of the controls required
for successful welding.
Course content: Review of aluminium
alloys, heat-treatable and non-heat-treatable alloys,
work hardening types; achievement of mechanical and
metallurgical properties; structure of the welded joint;
heat affected zones; weld metal metallurgy; welding
process selection; welding consumable selection; heat
input control; welding techniques; cracking and corrosion
in aluminium alloys – causes
and avoidance.
Suitable for: Non-welding personnel
including Engineers who are required to appreciate
weldability problems and solutions the successful welding
of aluminium. 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 and how
such problems can be avoided
- Understand different weldability concepts.
