Accreditations and Affiliations
Northern College’s School of Welding Engineering Technology is leading the way in welding education as an authorized training body for the International Institute of Welding (IIW).
Certification as an International Welding Technologist through the Canadian Welding Bureau (CWB) provides our technology graduates with job opportunities in 38 IIW member countries across the globe. Welder Fitter graduates may complete Canadian Bureau testing.
Northern College’s School of Welding Engineering Technology is the only welding education facility in Ontario associated with an applied research centre. The Materials Joining Innovation Centre (MaJIC), located on Campus, provides students access to additional sophisticated state-of-the art equipment and allows them to work on real-life industry derived projects.
What you learn
In this course, students are introduced to the various types of welding power sources, wire feeders and welding guns. Extensive use of a data acquisition system allows students to understand and apply static and dynamic power source characteristics for the short circuit GMAW process. This course also deals with the flux cored and gas metal arc welding processes. Students are expected to set up and demonstrate the safe use of FCAW and GMAW equipment. Data collected during lab sessions is used to complete comprehensive technical lab reports.
The metallurgical aspects of the welding processes are studied. The interaction between heat source, structure and properties of welds is studied in greater depth. Weld ability of different materials (steel, stainless steel, cast iron, aluminum, polymers) is also discussed.
This course introduces students to the submerged arc and gas tungsten arc welding processes. Electric resistance welding is also included with emphasis on spot welding. Students are expected to demonstrate the proper set up and safe use of SAW, GTAW and ERW equipment. Students will learn how to document welding procedure specifications and qualification records.
This is an advanced course including a detailed study of the production of iron and steel along with the effects of the major alloying elements. The mechanisms of, and control of, hydrogen-induced cold cracking (HIC) is studied and tested in detail. The weld ability of HSLA steels is studied in detail using the British and Japanese methods to avoid HIC.
This is an advanced course dealing mainly with the flux cored, gas metal and submerged arc welding processes. Particular emphasis is placed on pulse-arc wire feed processes. Students are required to develop and test weld procedures using these processes and prepare cost analyses. The problems of arc blow and grounding are also studied.
This is a detailed study into metallurgical problems encountered in the welding of special steels for power, petroleum, chemical and aerospace industries. With each group of steel, the problems of cracking and corrosion are studied along with practical means of their control. The weldability of cast irons and nonferrous alloys including aluminum, titanium, reactive and refractory metals will be studied in detail.
The first section of this course deals with the equipment and typical applications of processes, such as electron beam, laser, diffusion, electroslag and thermit welding. The second part of the course requires students to develop, document, qualify and cost welding procedures using knowledge acquired in welding processes, metallurgy, non-destructive examination and welding costs.
