4 Types of Welding Used in Welding Fabrication

June 20, 2022

Metal fabrication is a process that is required across various industrial sectors. It is a process that must be done meticulously with no scope for error. There are six basic steps of custom sheet metal fabrication namely, designing, cutting, forming, assembling, finishing and installing. In short, the raw material is cut as per the desired design and assembled together before installation. Assembling is done with the help of bonding, screwing or riveting. 


However, the most common assembling technique is welding. Highly skilled labourers and methods are required to complete the welding task effectively. Demtra is a trusted name when it comes to welding fabrication in Toronto. We use cutting-edge technology and tools to provide effective welding fabrication. In this blog, let's check out the various types of welding used in welding fabrication.


4 Welding Fabrication Methods



Shielded Metal Arc Welding or SMAW is widely used in industrial and steel fabrication. It involves the use of a consumable electrode. An electric current, either AC or DC, is used to form an electric arc between the electrode and the metal joints that need to be welded. It is also known as manual metal arc welding or MMA or MMAW.


Gas Tungsten Arc Welding (GTAW) uses a tungsten electrode for welding purposes. In this type of welding, the weld area and electrode are protected from oxidation with the help of an inert shielding gas which is mostly argon or helium. This is why GTAW is also called tungsten inert gas welding. 


Gas Metal Arc Welding is also referred to as Metal Inert Gas. In GMAW, a shielding gas heats up along with a wire electrode to carry out the welding process. GMAW is one of the most common welding styles used across many industries.


Flux-cored arc welding is a welding process that uses the heat generated by a DC electric arc. The arc is struck between a continuously-fed consumable filler wire and the metal joints.
