Welding
Inspection
The course discusses both
qualification inspections and
on-line inspections of
welded joints. These include
mechanical tests (tension,
bending, impact, ...etc, and
non destructive tests.
Significance of weld
discontinuities. Welding
inspection (non-destrutive
testing techniques: surface
inspection, magnetic particle,
volumetric, radiography, and
ultrasonic). Destructive testing
techniques: hardness, tension,
bending, ...etc. The control of
quality during shop operations.
The control of quality during
site welding.
Non
Destructive
testing
Certification:
Magnetic
Particle &
Liquid
Penetrant
Testing (MT
& PT)
Level I: Is to train inspectors
to be able to pass level I
examination and to be able
to inspect using the chosen
technique. Level II: Is to
upgrade level I inspectors to
be able to pass level II
examination and to be able
to inspect, write a report, etc
in the chosen technique.
Physical principals of test.
Processing. Test equipment
and materials. Codes,
standards, procedures and
safety. Test physical
principals. Equipment and
radiation source. Radiographic
recording. Work parameters
and conditions. Defectology.
Selection of techniques. Test
methods according to
standards. Personal safety and
protection.
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
in welding. Effect
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
