Welding Fabrication in Toronto

May 23, 2017

Welding fabrication in Toronto is perhaps the most familiar of metal fabrication processes. Welding is interchangeably used with metal fabrication. Welding is one among many fabrication processes to join two parts of metal using fusion. It is often used to form metal. There are many different ways of welding that include tungsten arc welding, metal arc welding, flux-cored welding and shielded metal arc welding, which are the four most popular ways.


Read on for the advantages and disadvantages of the above types of welding fabrication:


Tungsten Arc Welding (TIG)

Commonly known as TIG in Toronto, this type of welding can be used in welding most alloys. It is used in fabricating aerospace metals, motorcycles and piping systems. It produces high quality jobs and can weld very thin sheets of metals. Using TIG offers spatter-free work and highly aesthetic finishes.

However, the equipment is expensive and requires high-level training. For clean finishes, the material must be dust and dirt-free. TIG also requires external shielding gas.


Metal Arc Welding (MIG)

This type of welding is common in manufacturing plants. It is excellent for welding automotive bodies. It is highly efficient, with minimal messes. It requires low heat inputs, emits fewer fumes and is very easy to learn.

However, it is not efficient for welding thick materials and cannot be used in vertical positions. MIG equipment is expensive and requires external shielding gas.


Shielded Metal Arc Welding (Stick)

Also known as Stick, this type of welding is commonly used for heavy-duty welding in pipelines and construction sites. Its low cost equipment is easily portable and can be used on rusty and dirty metal. It does not require shielding gas.

Using Stick produces a lot of waste and cannot be used on thin materials. It requires high-level training.


Flux-cored Arc Welding

This welding type is similar to MIG except that it uses tubular wire filled with flux instead of solid wire. It is recommended for thick materials and heavy equipment repairs and steel erection. It is efficient, requires no shielding gas and gives out fewer fumes. Its equipment is expensive and is difficult to use on thin sheets.


Welding fabrication in Toronto involves working with hot metal and can therefore be dangerous. Welders are advised to adhere to safety precautions. Consult the experts at Demtra Sheet Metal for all of your welding fabrication in Toronto!
