3 Popular Welding Techniques - Welding Fabrication in Toronto
3 Popular Welding Techniques - Welding Fabrication in Toronto
June 12, 2018

Welding is a technique that is at the center of metal fabrication, a staple in assembly and production of metal products and parts used in countless applications. Welding fabrication in Toronto is commonly used in construction, assembly, custom work, machinery, manufacturing and much more. At Demtra, we take pride in offering high quality and precision in any fabrication project.


With a certified and experienced metal fabricator, any enterprise can have metal work and pieces made with extreme accuracy, using CNC technology, or employ a range of traditional machining and welding options to meet any particular need.


Welding fabrication in Toronto usually entails one of these methods:


Gas Metal Arc Welding (GMAW)

Also referred to as Metal Inert Gas (MIG), it's the most common welding technique. It utilizes a shielding gas with a wire electrode that heats up the two materials set to be combined. There are four ways for the metal to be transferred – globular, spray, pulsed-spray, and short circuiting. The process also demands a constant power source and voltage.


Gas Tungsten Arc Gas Welding (GTAW)

This welding process uses a non-consumable tungsten electrode. The electrode is used to heat up the base metal and make a molten metal pool. Melting the two metals creates an autogenous weld. This welding technique is also called Tungsten Inert Gas (TIG) and is a very complicated process that requires highly trained welders. TIG welding is used when the job requires high-quality finish.


Shielded Metal Arc Welding (SMAW)

This is the simplest of all welding types. Sometimes referred to as arc welding or stick welding, it utilizes a welding stick to develop an electric arc between the metals to be combined. This technique is often used to weld together iron and steel, hence the method is often seen in industrial fabrication and steel structures, as well as construction, manufacturing and repair work.


These are the most common techniques employed in commercial welding fabrication in Toronto’s booming industrial and commercial sectors. To learn more about customized welding fabrication, contact an expert at Demtra Steel Fabrication today.
