|
Welding Fundamentals |
The main objective of this course is to familiarize engineers and inspectors to various aspects related to welding techniques, inspection and quality procedures in welding industry. The course is designed for engineers of scientists with no or little experience in the welding field. |
Welding processes: Shielded metal Arc welding, Arc welding, Gas tungsten Arc welding, Submerged Arc welding & Oxyfuel welding & electric resistance. Cutting processes: Oxygen cutting, plasma cutting and laser cutting. Inspection of weldments: Nondestructive testing of welments. Mechanical testing of weldments (tensile, bending, impact). |
|
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: |
Level I: Is to train inspectors to be able to pass level I examination and to be able to inspect using the chosen |
Physical principals of test. Processing. Test equipment and materials. Codes, standards, procedures and |
|
Magnetic Particle & Liquid Penetrant Testing (MT & PT) |
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. |
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 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. Qualification of 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 Techniques |
Selection of the welding process is very important. The course discusses the variables of each welding process and gives directions for selecting the proper |
Overview of welding techniques and processes. Conventional techniques: arc, Oxy fuel and resistance welding. Non-conventional: plasma, electron beam, laser |
|
process for specific application. Welding processes discussed include: SMAW, GMAW, GTAW, etc. |
welding. Flame and arc cutting of metals. Computer applications in welding. Case studies. |
