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, and modify to 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, CSA S-6 or CSA S-16.

This course will give you an opportunity to understand welding and related processes and their application. This course will also teach you 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 your welding questions, problems, and projects to the class. 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 skyscrapers, hydroelectric gates, bridges, etc., the principles of metallurgy and welding engineering covered in the code can be applied to a 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 the 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.

Mr. Viwek is a metallurgical engineer with over 40 years of experience in the welding, fabrication and inspection fields.

His projects include bridges, hydroelectric power stations, nuclear and fossil power stations, pulp and paper mill equipment, pressure vessels, aluminum smelters, refineries, and transportation equipment. Viwek was recognized as a Senior Welding Expert at Air Liquide SA and is the inventor of 101.Lean.Welds methodology. On 15th June 2022, Viwek was awarded the prestigious Michael Vuchnich annual award for promoting welding Technology in Canada and has now joined the elite group of 23 Top professionals in Canada!

Viwek and his colleagues audited over 100 welding shops in North America and Europe to create a proven methodology to optimize welding operations for quality & productivity. The principles of this methodology are now incorporated in the ISO 3834 welding quality standard equivalent to the CSA W47.1 code. Viwek is an active member of the CSA W59-13 technical committee and CSA W117.2 Committee on Safety. Viwek is a Vice Chair of the CSA mirror committee to ISO TC44 global welding and inspection standard.

Viwek is a litigation expert and teaches Welding and Inspection to graduate students at Concordia University, Montreal.
