Course Description

Welding Technology plays a major role in all maintenance and fabrication activities in the industry. Production equipment, a highly sophisticated welding technique and qualified personnel allow processing or production of steel products for different applications within short periods. This seminar provides a much needed source of authoritative information on the complex subject of welding. It provides a comprehensive run-down of the complex science of welding- processes, selection of power sources, weld metallurgy, weldability of metals, testing and inspection techniques.

The seminar will cover welding processes, welding consumables, design of welded joints, applied welding metallurgy and heat treating, welding quality control, non-destructive testing and major International Welding Codes and Standards such as AWS and API.

Each session will be conducted in a lecture/discussion format and videos designed to provide intensive instruction and guidance. The director will be available following each day’s session to provide participants with further opportunity for discussion and consideration of specific problems.

Course Objective

• Upon the successful completion of this seminar, the participants should be able to:
• Identify the tools and techniques associated with welding-related fabrication and quality control.
• Point out practical aspects of fabrication and inspection which should be taken into consideration in the design of equipment.
• Monitor fabrication and erection plans and incorporate some quality control requirements into contractual documents.
• Achieve economical compliance with ASME, AWS and API Standards when writing and qualifying welding and brazing procedures.
• Gain insights into ASME Code, AWS and API Standards to facilitate interpreting, understanding and complying with Standards.
• Review welding processes, common variables and basic welding metallurgy.
• Find out how to qualify welders and brazers the easy way.
• Writing and qualifying welding procedures that comply with ASME Code, AWS and API Standards with an in-depth understanding of the requirements.
• Understand and examine the requirements for welder and operator qualification in details and in an easy way.
• Select test coupons to minimize overall cost of qualification and writing WPSs so that optimum flexibility is achieved

Who Should attend?

Inspection engineers, Mechanical Engineers, Electrical Engineers, NDT personnel, quality assurance personnel, auditors, testing laboratory personnel, and maintenance personnel. Further, this seminar is a must for anyone involved in inspection of welding construction, qualifying welders, brazers and operators; or other involved in writing and qualifying welding and brazing procedure specifications; those responsible for reviewing supplier procedures, auditing or reviewing in-house procedures and qualifications; and those who estimate jobs where compliance of ASME code.
