You probably have an idea of what welding is. Do the bright light and buzzing sound which ends up joining two metals together ring a bell? It ends up turning pieces of metal into works of art, or for applications in industries ranging from agriculture to oil and gas. 

Did you know there are different types of welding? While all these methods achieve the same thing, how they operate is what sets each apart. This difference in operation makes one type of welding suitable for certain kinds of applications in comparison to the others. Let’s take a look at four of the most popular welding types. 

MIG Welding 

This type is also known as Gas Metal Arc Welding. Many welding enthusiasts consider it to be one of the easiest for beginners to learn and master. It’s a type of arc welding involving bare wires, of which there are two types: an electrode and a flux core.

The electrode MIG welding operates by feeding a wire through the welding gun. A shielding gas accompanies it to protect the new weld from contamination. Flux core welding is suitable for outdoor use as it does not require a gas supply.

MIG welding is suitable for auto industry repairs, construction, and renovations. It’s also a favorite of enthusiasts.  

TIG Welding

Experts refer to this type as Gas Tungsten Arc Welding. It is also an arc type of welding but utilizes a tungsten rod to create a bond between two pieces by fusion. The TIG welding process also requires a gas supply such as argon or helium. 

TIG welding is a two-handed job, as one hand holds the TIG torch while the other feeds into the tungsten rod. The ability of tungsten to bond with many diverse metals makes it a very versatile process, and also a tad more difficult technique to master.

Professionals in aerospace and other industrial markets prefer this welding technique. 

Stick Welding

Stick welding is also known as shielded metal arc welding. It’s an old-fashioned technique, which many love for its portability and ease. This method utilizes a metal electrode stick with a protective cover. Whenever a current is passed through it, the stick and the protective cover combine with the metals through an arc. The protective cover is meant to shield the melting stick from contamination by oxygen and other present gases.

By merit of being an older technique, stick welding is widespread in industries ranging from construction and underwater pipeline repair to industrial fabrication, among others. 

Flux Cored Welding

Flux Cored Arc Welding is quite similar to MIG welding as they both use a continuous wire core and other supplies. In this case, the electrode consists of a hollow tube through which flux passes through the gun. In cases where outdoor welding is necessary, a gas shield covers the flux core welding to protect against contamination and weather elements. 

Flux Core Welding is the best method when handling thicker metals, and also during machining processes.

“When my youngest child graduated from high school, I told my husband that it was my time. I went back to school to change careers after spending 37 years in the business field. At SCI, the instructors are professional, and they care about what they are teaching you, as well as expect you to give 100% in return. I had problems understanding how to draw in syringes and give injections. I requested extra help from a knowledgeable instructor, and I was able to receive one-on-one training. Today, I draw injections for approximately 100 patients each week. I am very confident in what I’ve learned. SCI has given me the chance to do what I always wanted to do. Thank you for my education. I am doing wonderful.”
