What Is Welding? What Are the Common Types of Metal Welding?
Without a doubt, metal welding is an energizing and pleasing process for enthusiasts and experts. With the help of a few tools along with a few kinds of metals, welders have the ability to change any piece into any form, and design people demand.
Though, so as to have the option to ace the welding art, you are required to begin with the fundamentals and know about the various sorts of metal welding processes.
You would be surprised to know that there are over 30 different kinds of welding techniques. The techniques include basic oxy-fuel to innovative processes, for example, laser beam welding.
Though, in most cases, just four types of metal welding techniques are utilized:
- Flux- Cored arc welding
For this situation, there are unique benefits, along with downsides that are associated with each sort of technique. You are required to have adequate training to execute each process. You can also search, metal welding shop near me in case you need help regarding welding.
Let’s dig deep to find out different types of welding.
MIG – Gas Metal Arc Welding (GMAW)
It is a basic type of welding technique that can undoubtedly be performed by new welders as well. The full form of MIG is Metal Inert Gas. Though, in some cases, it is named Gas Metal Arc Welding (GMAW).
The process takes little time and includes the filler metal being fed through the wand, whereas gas is expelled around it to cover it from outside components. It implies it’s not appropriate for outside use. In any case, it’s an adaptable process and can be utilized to weld various sorts of metal at various thicknesses.
In this case, the filler metal is fed from a spool, it is a consumable wire, and it also works as the electrode. At the point, the arc is made from the tip of the wire to the base metal, the wire dissolves turns into a filler metal, and make the weld. The wire is constantly fed through the wand; as a result, you get the option to dial in your favored speed. With the adequate technique, the welding produces a smooth and tight weld that is also visually enticing.
The welding process is amazingly flexible. However, it is also a hard and intricate technique with respect to learning. In order to carry out the process, two hands are required. One hand takes care of the rod while the other one is utilized to hold a TIG torch.
The torch performs its role to heat and arc, which are utilized to weld most conventional metals, for example:
- Cobalt & titanium
- Copper alloys
- Nickel alloys
Stick – Shielded-Metal Arc Welding (SMAW)
The sort of metal welding technique that took place in the 1930s, however, keeps on being optimized and improved today. It has stayed a famous type of welding technique since it is straightforward to learn, along with being economical to carry out. Though it doesn’t make the neatest welds, based on the fact that it splatters easily, as a result, in most cases, cleanup is required.
A replaceable electrode “stick” also works as filler metal. An arc is made that connects from the end of the stick to the base metals, softening the electrode into filler metal and making the weld. The stick is covered in flux that makes a gas cloud when warmed up and covers the metal from oxidation. As soon as it cools down, the gas sits on the metal and turns out to be slag.
Flux Cored Arc Welding (FCAW)
Like MIG welding, the welding, in this case, also revolves around a nonstop wire feed process. There are two distinct procedures related to flux-cored arc welding. One includes the utilization of shielding gas, though the other depends on self-shielding formed when fluxing agents break inside the wire.
This kind of metal welding is acknowledged for being economical and simple to learn. Similar is the case with the MIG welding technique; it’s an effective route for new welders to commence their professions in the field. It additionally lets welders carry out their work outside.
In the case of the weld joint, it is intended to endure the forces to which it is required to be exposed to during its operational life. It implies the design of the joint is decided by the sort and size of the load that is relied upon to follow up on the weld. Specific kinds of welding joints are intended to endure outrageous shear loads, though others are intended to endure extraordinary torsional loads. The following are common types of joints that are utilized in welding:
The Following Are Common Welding Techniques
In most cases, pressure metal welding is extremely specific and isn’t utilized outdoors. In any case, fusion welding procedures, for example:
- Gas metal arc welding
- Gas welding
- Arc welding
These processes are utilized in a significant number of industries. In the process of gas welding, two parts of the metal are locally warmed to past their dissolving point, at which time they successfully become one piece of metal.
It is possible to carry out with or without an alloy rod. Examples of gas metal arc welding processes include metal inert gas and tungsten inert gas. In the case of arc welding, a metal welding rod is utilized that is melted to help structure the welded joint.
The arc sorts of welding all require power at comparatively high voltage and current. Inert or active gas is utilized in the case of gas metal arc types to make a wall between the weld and the climate, improving the quality and strength of the joint.
At this point, you should have essential knowledge of the various sorts of metal welding. Particular sorts are carried out by machines and require costly equipment. Some can be carried out by a beginner at home without using expensive material and requiring expensive material.
