Welding
Metallurgy
The course delineates the
main changes in the
microstructure and/or the
morphology of the metals
and alloys during welding
that lead to changes in
properties. Alloys discussed
in the course include all
types of steels, Cast Iron,
Nickel, Copper alloys, ...etc
Heat flow

of pre-and-post weld heat
treatment. Introduction to
welding metallurgy
(hardenability and
weldability). Metallurgy of
steels. Welding of ferrous
alloys: Carbon-steels, Low
alloy steels, Stainless steels,
and Cast Iron. Welding of non
ferrous alloys: Al- Ni- and
Cu-alloys. Identification and
specifications of welding filler
metals. Case studies.
Welding
Quality
Assurance
For each application, the
welding process is
controlled by specific code
or standard. The course
includes discussions of
ASME boiler and pressure
vessel code AWS steel
structure code and other
standards.
Welding co-ordination: tasks
& responsibility. Quality
requirements for welding.

procedures and welders.
International codes and
standards. Mechanical testing
of welds. Non-destructive
testing of welds. Documents
for weld quality assurance.
Case studies.
Welding

Selection of the welding
process is very important.
The course discusses the
variables of each welding
process and gives directions
for selecting the proper
