What is welding? <\/h2>\n\n\n\n
Welding is the process of using high heat to melt and fuse metal parts. Depending on the technique, additional filler materials like electrodes, wires, or rods are often used. These melt alongside the metal to form a solid joint once everything cools down. <\/p>\n\n\n\n
Types and methods of welding <\/h2>\n\n\n\n
Since the invention of welding a number of welding methods have emerged, each harnessing different energy sources or ways of processing materials. Here\u2019s a rundown of the main welding types based on their energy sources:<\/p>\n\n\n\n
- \n
- Gas<\/strong> welding<\/strong> \u2013 uses a gas flame (such as acetylene) to heat the edges of metal parts, fusing steel or non-ferrous metals. <\/li>\n\n\n\n
- Electric<\/strong> welding <\/strong>\u2013 an electric arc between the electrode and the metal generates the heat needed for welding. It\u2019s effective for metals between 1 and 80 mm thick. <\/li>\n\n\n\n
- Thermit welding<\/strong> \u2013 a mix of iron oxide and aluminium is ignited, creating an exothermic reaction that produces molten steel. This method is great for welding railway tracks, steel rods, and cast iron components. <\/li>\n\n\n\n
- Laser<\/strong> welding <\/strong>\u2013 a cutting-edge technique that uses a high-powered laser beam to weld metals like steel, nickel, titanium. It handles all shapes and welding positions with ease. <\/li>\n<\/ul>\n\n\n\n
This article will focus on electric welding, a method extensively used in the automobile industry, mechanical engineering, as well as for DIY projects. We will discuss the different types of welding machines<\/a> and the three most commonly used methods: TIG, MIG\/MAG, and MMA welding.<\/p>\n\n\n\n
TIG welding <\/h3>\n\n\n\n
TIG welding is distinguished by its use of a non-consumable tungsten electrode. The arc’s heat between the electrode and the metal melts the metal, while filler rods can be added to create a stronger weld.<\/p>\n\n\n

TIG welding<\/strong><\/em> relies on an inert gas to protect the weld pool (the molten metal formed during welding) from contamination, which contributes to a more robust and corrosion-resistant weld.<\/p>\n\n\n\n
MIG\/MAG welding <\/h3>\n\n\n\n
MIG<\/strong><\/mdspan><\/a> and MAG welding are very similar techniques. Both involve using a welding wire to create an arc that generates enough heat to melt the wire and form a solid weld between metal parts.\u00a0<\/p>\n\n\n \n\n- \n

The main difference lies in the shielding gas. MIG uses inert gases like argon, while MAG uses active gases such as carbon dioxide. Inert gases don\u2019t react with the molten metal, whereas active gases do. Both help to protect the weld from external contamination. <\/p>\n\n\n\n
Welding with electrodes <\/h3>\n\n\n\n
Last but not least, let\u2019s discuss electric welding, also known as MMA or stick welding. It uses a metal-core electrode with a special coating. As you weld, the core melts and the coating releases protective gases. This welding technique<\/a> also leaves slag that needs to be cleaned off once the weld has cooled.<\/p>\n\n\n

What should I know about aluminium welding? <\/h2>\n\n\n\n
Welding can be used to join a variety of metals and alloys, but some require extra skill to avoid damaging the material. Aluminium is a prime example. <\/p>\n\n\n\n
