What could be more intimidating than a machine that has the power to fuse metals together and when handled inappropriately, could injure you?
Although it’s no doubt that welding can be quite unnerving, like anything else, with the right tools and enough effort to learn, you can master the process and complete whatever project you may have in mind.
If you’re new to welding, we think the best topic to start off with is about the welding processes, themselves.
6 Different Types of Welding Processes
The types of welding machines are primarily divided into three categories, which are based on electric heat, electric heat & gas, and explosion and reaction isotherm. Although there are three categories, we’ll be focusing on the first one.
• Welding Process Based on Electric Heat
1. SMAW (Shield Metal Arc Welding) is arguably the most widely used technique for almost any welding work. Here, an electric arc flame is used as the heat source for liquefying metal.
2. SAW (Submerged Arc Welding) involves the formation of an arc between the fed wire and the metal. A blanket of powdered flux is used to prevent the oxidation of the liquid metal.
3. ESW (Electro Slag Welding) is a process that’s typically employed to weld thick metals that are in a vertical or nearly-vertical position.
4. SW (Stud Welding) is the method of attaching a metal fastener, called metal studs, to another metal component. Stud welding machines are widely available in Singapore.
5. ERW (Electric Resistant Welding) refers to a group of welding processes like spot and seam welding wherein the heat used to weld is generated by the electric resistance of the materials and the force used to hold them.
6. EBW (Electronic Beam Welding) is a fusion welding process that uses a beam of high-velocity electrons to join two materials.
There are many other types of welding processes and machines to discover (e.g. automatic welding carriage, auto gas cutting machine, etc.) but, we’ll discuss them in the future articles.
