MTRL 472: Welding and Joining of Materials – UBC (my signature course)

A blended 4th-year course including a broad understanding of welding engineering, and developing skill of welding simulation.

This course presents the theory, fundamentals, and practice of welding science and engineering, including welding processes, welding flaws and imperfections, inspection methods, weld drawing, and practical application of weld modelling and simulation when developing a solution to a weld engineering problem. The course provides a comprehensive understanding of arc’s physics, modes of metal transfer, and thorough coverage of the arc welding processes namely, SMAW, SAW, GMAW, and GTAW as well as resistance welding processes where students understand the fundamentals and the influence of the process parameters on weld shape, intrinsic properties, and associated quality. Under the topic of weld quality, the course opens the subject of weld imperfections including, weld flaws such as cracking, undercut, porosity, inclusions, etc. Each weld imperfection will then be linked to the acceptance criteria within the common CSA standards, such as W59 and Z662. The weld quality topic continues with broad coverage of inspection methods, namely, VT, PT, MT, ET, UT, and RT. There will be an introduction to weld symbols and the concept of WPS/PQR based on ASME Sec IX.

The course includes a theory and weld simulation lab, where students learn about the weld modelling software; more importantly, they learn and implement how to address a frequent welding challenge by using the software. Typically, none of the students has ever experienced welding simulation. At the end of the semester, they learn about the software and implement how to address a frequent welding challenge by using the software. In the last session of the class, the students present term-projects where they teamed up in different groups to innovatively develop welding solutions using a computational package (UBC Link).

• Fall 2023
  With a total of 19 students in my class—comprising 5 graduate students and 14 undergraduates—five student groups delved into contemporary challenges. They ingeniously devised and presented welding solutions for these challenges, utilizing the Simufact Welding software package (Official Evaluation)(Group Picture).
• Fall 2022
  I had 23 students, including 4 graduate students and 19 undergraduate students, five student-groups innovatively developed and presented a welding distortion plan for a panel structure using QWeld Interface software package on Abaqus  (Official Evaluation)(Group Picture).
• Fall 2021
  I had 27 students, including 6 graduate students and 21 undergraduate students, six student-groups innovatively developed and presented a welding distortion plan for a panel structure using QWeld Interface software package on Abaqus  (Official Evaluation)(Group Picture).
• Fall 2020 – Virtual
  I had 36 students, including 1 graduate student and 35 undergraduate students, seven student-groups innovatively developed and presented a welding distortion plan for a panel structure using QWeld Interface software package on Abaqus  (Official Evaluation)(Group Picture).
• Fall 2019
  II had 34 students, including 4 graduate students and 30 undergraduate students, seven student-groups innovatively developed and presented a welding distortion plan for a panel structure using Abaqus Welding Interface software package (Official Evaluation)(Group Picture).
• Fall 2018
  I 38 students, including 13 graduate students and 25 undergraduate students, six student-groups innovatively developed and presented a welding distortion plan for a panel structure using Abaqus Welding Interface software package  (Official Evaluation)(Group Picture).
• Fall 2017
  I 38 students, including 13 graduate students and 25 undergraduate students, six student-groups innovatively developed and presented a welding distortion plan for a panel structure using Abaqus Welding Interface software package(Official Evaluation)(Group Picture). The course was highlighted in the Canadian Welding & Lifestyle Magazine – Welding Education Issue (Spring 2018).

MCG 5138-H: Welding Models and Computational Welding Mechanics, Winter 2014 UOttawa; (my signature graduate course) – I developed the course for the first time in Canada and delivered at the graduate level (University of Ottawa), received good evaluations from both audiences and the department, and hits the highest number of registration among five elective courses of mechanical engineering (Official Evaluation)(Group Picture). The course was included a welding simulation lab, and students delivered a weld sequence planning project using VrWeld software . The course was highlighted in the Canadian Welding Association Journal (June 2015).

ME 538: Welding Design, Fabrication, and Quality Control, Winter 2015 UOttawa; I developed the course for the first time at the University of Ottawa; managed and co-delivered together with an industrial instructor (Kevin Bagheri) and vice-president of services and safety from the Canadian Welding Bureau (Craig Martin). The course was highlighted in the Canadian Welding Association Engage Publication (July 2015).

Welding and Joining of Materials; I was a guest lecturer in Fall 2014 and Fall 2015 sessions (UBC-Materials) invited by Dr. Thomas Garcin, the primary instructor, to lecture on welding modeling and simulation aspects of welding engineering..
