Please note, This instructor-led course has specific dates and times:
This course is held online over 2 days on the following schedule (All times in Eastern Time Zone):
10:00 am to 6:00 pm Eastern (Will include the usual breaks and lunch)

After participating in this course, you will be able to:

  • Produce an engineering specification to repair, modify or make a welded structure
  • Understand global comprehension of steel and welding metallurgy
  • Understand and specify fundamental rules to avoid weld failures
  • Learn about conventional and advanced inspection methods PAUT, DR, CR
  • Understand the responsibilities of the owner’s engineer to the CSA W59-18 code requirements


Welding is a complex process and is often misunderstood. Most universities do not teach welding engineering to their engineers; however, engineers are required to assume responsibility for welded structures and bridges per the requirements of CSA W59-18.

This course will provide you with an occasion to understand welding and related processes and their application. This course will also teach you the notion of how to avoid faulty welds in structures by correctly specifying welding and inspection requirements in your contract documents.

This is an interactive course. You are encouraged to bring to the class your welding questions, problems and projects. Remember, there are no stupid questions!

Course Outline:

  • Case histories of weld failures
  • Understanding why the welds failed
  • Welding metallurgy for steel
  • HAZ and its characteristics
  • Welding processes and inspection
  • Welding requirements of CSA W59, S-6 and S-16 and ASME
  • Welding certification per CSA W47.1 code
  • Engineer’s responsibility per CSA W59 code
  • Advanced inspection techniques
  • How COBOTs are changing the welding world
  • Applying Lean to welding operations to prevent failures

Who Should Attend:
Senior and Junior Mechanical and Civil Engineers • Technicians • Plant and Facility Managers • Supervisors • Operations and Maintenance Personnel • Design Engineers • Consultants and Contractors • Inspection Agencies • Lawyers and Insurance Agents

Required Resources:

Participants may want to send in any specific welding related questions ahead of time to EPIC, so that potential solutions to these issues can be addressed during the 2 day training session!

Special Features:

The CSA W59-18 code is a good source of welding knowledge for engineers and technicians working in the metal fabrication industry. Although this code is aimed at building large steel structures like sky scrapers, hydro electric gates, bridges, etc., the principles of metallurgy and welding engineering covered in the code can be applied to great variety of welded steel components. It is imperative to understand that making sound welds does not only depend on the welder, but it also depends on the welding specification calling for the welds, tracing back the responsibility to the Engineer who writes out the specification and designs the welds. Selection of base materials, welding process, choice of filler metals, welding parameters, sound execution of welds with process control, receiving inspection, in process inspection and post weld inspection are part and parcel of the whole package to create sound and reliable welds.

The participants will be required to read several weld failure case histories to understand why weld failures occur. This knowledge will permit the participants to understand principles of welding metallurgy elaborated during the course and then will further guide them to make pragmatic choices while specifying welding work in their professional practice.
