Different Welding Techniques – An Overview

Different Welding Techniques – An Overview

Welding is simply the process of joining metals together by using a heating mechanism. The Egyptians welded iron during the Iron Age around 1000 BC. There are various types of welding processes and many techniques that are used today to mend iron and other metals together. Welding is a skilled trade, and for those considering a career in welding, a welder degree may be the best option for proper training and career placement. There are many techniques for welding using various technologies, but we will briefly examine three welding techniques; manual, semi-automatic, and automatic.

Manual Welding

First, manual welding is done mostly by hand and with the assistance of an electrode. This is the most common welding technique and it is also the oldest. During this procedure, you use the electrode and an electrode holder to weld the metals together. Arc welding is a common type of manual welding in which heat and the electrode is used to join the metals together.

Semi-Automatic Welding

Next, semi-automatic welding is a relatively new technique that is gaining popularity among many operators and welding training specialists. In this method of welding, the electrode is motor-driven and it set at speed to help the operator complete the welding task. Advanced techniques in welding technology can be found at your local vocational or trade school. Interview a welding instructor and you will get key information about the best techniques to use while working.

Automatic Welding

In automatic welding, the electrode is automatically placed along the metal joint to do the welding for the operator. Simply put, there are machines that will do Gas Metal Arc welding, Gas Tungsten welding, MIG, TIG and various other types of welding. Automatic welding processes are used to seal oil lines, gas lines, and water lines.

There are additional types of welding such as Electroslag, Flax- Core, Conventional, Pulsed, Plasma, Sheiled, or Submerged. There are many ways to operate and use welding machines and equipment.

There are many techniques that are used in welding and processes change as new products and inventions are brought to the market. A good welding school will be on top of the latest welding techniques and will be able to provide prospective students with information on the job market for skilled welders. As technology changes, the welding industry changes with it; adapting and developing stronger, more efficient welding techniques no matter the physical or economic conditions of the job.

For those exploring attending welder school, the industry provides a variety of career options around the world.
