5 Types of Welding Methods & Their Usage
Description A clean weld is not the first thing that catches the eye when one looks at a picture of The Golden Gate bridge. Like we mentioned in our blog, ‘The importance of the welding industry’, if you see more than one block of metal in an object, small or ginormous, it can be, and has, been welded.
In case you had any doubts, welding is not just the best way of joining two metals, it is also the only way to make the two different parts to act as a single piece of metal. But within welding, there are many types of it. In this blog article, we explain some of the most common ways of welding.
MIG Welding Metal Inert Gas or MIG welding is one of the easiest kinds of welding. It is the first welding that a beginner approaches and masters. It is also called GMAW or Gas Metal Arc welding as it is a type of arc welding. This is widely used across industries. Lets now talk about how it occurs and what welding material is required. The process involves the two materials to be welded, between which a solid wire electrode is heated, ultimately welding the two materials as one. Alloys and metals like stainless steel, aluminium and other such metals in thinner sheets are ideal for MIG welding.
SMAW welding
Stick welding or SMAW or Shielded Metal Arc Welding is a basic type of welding. It is also referred to as Manual Metal Arc Welding or MMAW or flux shielded arc welding among its other, more common names. It is now considered to be a more traditional form of welding. SMAW welding is done by using a metal filler electrode, also called a stick. It is put between the two materials to be welded and is molten by passing electricity through it. As opposed to MIG welding, SMAW welding is slightly more difficult to ace. It is apt for home welding needs, small repairs while it has also shown high efficiency in manufacturing and construction works. The materials commonly welded through shielded metal arc welding are carbon steel, cast iron, low as well as high alloy steel. Other materials on which it is seldom used on, are nickel, copper and its alloys.
TIG Welding
Tungsten Inert Gas welding or TIG welding is an arc welding technique. It is also called Gas Tungsten Arc Welding or GTAW. It is applicable to a wide variety of fields, but works wonderfully for industrial purposes. Of course, since it is a more advanced form of welding and thus, requires a higher level of expertise.
The process of TIG or Tungsten Inert Gas welding is more complex than most. It uses non-consumable tungsten electrodes. A TIG torch is required that heats the electrode to create an arc and ultimately weld. It can be used for a bunch of metals, including stainless steel, aluminum, magnesium, nickel and copper alloys and even titanium!
