4 Popular Types Of Welding Procedures In Trade Schools

What is welding?

Welding refers to joining two or more metals (or thermoplastics) using high heat or pressure. This process causes metals to fuse. The first signs of welding go as far back as the Bronze age. This technique has subsequently evolved through the years. Initially, it was just about hammering two metals together. Lately, however, it has become more technology-oriented with the introduction of A.I( Artificial Intelligence) and robotics. In addition, prominent welder trade schools provide welder certification programs to excel in the field. Welding programs in welder trade schools teach four popular types of welding techniques.

How is welding a great career?

Welding is associated with many industries that build power plants, buildings, and public infrastructure. They provide massive employment to people. Welding constitutes the fundamentals of any construction and manufacturing entity.

A recent report by Zion market suggests that the 2016 global market of welding products was at USD 20.67 billion, and it estimates that by 2022 it will reach USD 32.63 billion. Welding is one of the most popular trades among students in America. There are excellent welder trade schools that give students great career opportunities.

What are the four popular types of welding procedures?

We all know that welding has taken a modern form with technology and developed into a more scientific approach. Now welding incorporates the latest features that help the welders work with ease and precision and minimize hard labor work. However, a welder can only master a process if trained in a welder trade school. The following are the four most popular and latest welding procedures:

Gas Metal Arc Welding (GMAW/MIG)

It is also called Metal Inert Gas (MIG) welding. It uses a shielding gas with the wire electrode that heats the two adjoining metals. Constant and consistent voltage and a direct-current power supply are vital in the process.

It includes a plate and large bore pipe, one of the most common welding processes. Welding vocational schools such as trade schools in Philadelphia are an excellent choice.

GMAW uses four fundamental procedures to transfer metal:

    1. Globular transfer
    2. Short-circuiting
    3. Spray Transfer
    4. Pulsed-spray

Gas Tungsten Arc Welding (GTAW/TIG)

The most common use of this method is to weld together bulky sections of stainless steel or non-ferrous( metal that does not contain iron) metals. The process uses a fixed tungsten electrode as an arc welding process. However, it is a time-consuming process compared to the other three methods.

The metal must have at least 11% Chromium to be Stainless Steel.

The constitution of 11% chromium lowers that temperature range to weld the stainless steel, which is essential for joining the metal. It requires excellent welding skills to weld aluminum. Hence welder training from a certified welder trade school is crucial in making a skilled welder.

Shielded Metal Arc Welding (SMAW)

In this process, the welder follows a manual method of stick welding. They put metals between the sticks that use an electric current to build an arc. Steel structures, welding of iron and steel, and steel pipe are all welded using the process.

The welder must be able to weld to the degree that can reach a destructive kind of bend test. So here comes the role of the welding certification program to teach you all the skills.

Flux Cored Arc Welding (FCAW)

It is a substitute to shield welding. Many construction projects use this method mainly due to its easy portability and fast speed. The technique uses a semi-automatic arc weld that you can use widely due to the variables. These variables depend on many factors.

The elasticity widens by the many operational angles, wire speed, voltage levels, and polarity used. With the capability of rapid welding, the freshly joined metal cools faster. While using flux-cored wire, the welder must look out for porosity in the welded joint.

FCAW is very efficient indoors or outdoors or under industrial ventilation hoods. It prevents the smoke from emerging during the welding process. Therefore budding welders must attend welder trade school to gain the proper knowledge and welder training.


To operate the welding technology or processes, one must be thoroughly prepared. Students must join a welder trade school or welding certification programs to acquire knowledge, skills, and expertise. Welder training is essential in the trade. Welding holds immense opportunities with the advancement of technology.

Welding vocational schools are the perfect place to invest your money to receive lifelong benefits with a stable career and handsome salaries. Students must carefully select the welding trade school, such as the welding school in Philadelphia.
