Types of Welding – Welding Technology

One of the essential fabrication processes in the industry is welding technology. In this process, two or more parts are fused using heat, pressure, or cooling to form a joint. Welding can be done on various metals and non-metals and is essential in metallurgy and manufacturing industries. Learning about welding technology from one of the top welding tech schools can give you an edge in your career. Different types of welding take place using various techniques depending on the type of materials to be fused. Here is a brief overview of the common types of welding in which you can get Welding Certifications from the best welding tech schools in the U.S.

Metal Inert Gas (MIG) Welding

This process requires proper training from a welding certification program. In this welding process, they heat the workpiece metal(s) by an electric arc that forms between a consumable wire electrode and the workpiece metal(s), which melts and eventually cools, which causes these to fuse. Inert shielding gas is supplied through the welding gun along the consumable wire electrode to shield the electric arc to prevent contamination from the surrounding air, ensuring that no surrounding gas can contaminate the process.

Metal Inert Gas (MIG) Welding accounts for more than 50% of all deposited metal welds in the industry, and it comes in use widely. It is a modern, improved arc welding process that is flexible and suitable for mechanization and is a highly lucrative and sought-after skill in the welding, fabrication, and metal joining companies in the Tri-state area. Welding Certification in this technology will give you an edge as a skilled welder. A high degree of manipulative skill expects of a qualified Metal Inert Gas (MIG) Welder in the industry.

Tungsten Inert Gas (TIG) Welding

The only difference between Tungsten Inert Gas (TIG) Welding and Metal Inert Gas (MIG) Welding is the addition of filler metal in the welding process. In Tungsten Inert Gas (TIG) Welding, the heating of workpiece metal by an electric arc formed between the workpiece metal and a non-consumable Tungsten wire electrode where the use of filler metal is to add to the weld pool (where the workpiece metal and filler metal melt and eventually cool). Surrounds this area by an inert gas, usually Helium or Argon, similar to Metal Inert Gas (MIG) Welding, which shields it from oxidation and other contamination by the surrounding atmosphere.

The advantage of Tungsten Inert Gas (TIG) Welding over Metal Inert Gas (MIG) Welding is that it is suitable for all industries but requires high-quality welding and comes in wide usage in mechanized modes. The welding operator must have the proper training to give precise attention to the joints and welding parameters. The employment opportunities that open up by learning Welding Technology from the best welding schools in the U.S can provide a skilled welder the sustainability and stability in their career and scope for attaining better opportunities in the industry.

Shielded Metal Arc Welding (SMAW)

One of the typical welding techniques is Shielded Metal Arc Welding. It is a manual arc welding process that requires a flux-coated consumable electrode and the surface of the workpiece metal to melt and fuse to create the weld. In this process, gas and slag are formed during the heating, preventing contamination from the surrounding atmosphere and protecting the weld area. The slag cools off and solidifies and must chip off before the metal workpiece becomes usable for the following process.

The skills of the welder determine the quality of the weld. So a qualified welding technician is particularly valuable to the industry as this simple and versatile welding technique is ruling the repair and maintenance sector of the metal fabrication industries.

Flux Cored Arc Welding (FCAW)

Flux Cored Arc Welding (FCAW) is a semi-automatic or automatic welding process where the consumable electrode has a flux core and continuously gets feed. Depending on the material in the flux core, the necessary process to eliminate atmospheric contamination is determined. For example, in one type of Flux Cored Arc Welding (FCAW), the core contains flux and other materials that produce a shielding gas during the welding process, preventing contamination by protecting the welding arc. And in the different types of Flux Cored Arc Welding, an external source of shielding gas is supplied to protect the weld pool from oxidation.

Flux Cored Arc Welding (FCAW) is portable, highly productive, and produces high-quality welds. Therefore, the employment opportunities for a certified welding technician in Flux Cored Arc Welding (FCAW) from a welding tech school are high due to the requirements of this technology in the construction industry due to the portability, ease, and flexibility of operations.
