What are the different types of welding methods?
In the following post, we’ll cover the fundamentals for every sort of welding method. This includes everything from oxy-acetylene brazing to stay welding to underwater welding.
Additionally, you’ll find differing types of welding methods, safety tips.
Different Types of Welding Method:
Arc Welding Basics
Sometimes the term “arc welding” is often confusing, which is why we’ve designed TFC’s Official Arc Welding Basics Cheat Sheet. First, we’ll start with an honest definition of arc welding. Then we’ll advance to arc welding uses the various sorts of arc welding, and tips and techniques. We’ll also cover tricky comparisons, like Arc vs Mig welding. Everything you’ve ever wondered about arc welding is here, in one easy spot!
Simply put, arc welding may be a sort of electric welding that permanently fuses base metals by forming an arc between the metals and therefore the electrodes.
An electrode may be a sort of wire that connects the welding machine to the metals you’re melting together. The electrode could also be consumable or non-consumable.
What’s the difference between consumable and non-consumable electrodes?
Commonly, consumable electrodes have quite one purpose: they contain a filler metal, which liquefies throughout the method. this is often common in Stick and MIG welding, and therefore the filler metal can cause quite mess when it melts! Typically, these are the well-liked methods.
On the opposite hand, TIG welding uses non-consumable electrodes. One major benefit is that this method is far cleaner and creates the foremost precise welds. However, it’s also the foremost difficult, and it takes the foremost time. generally, TIG is for welding extremely thin sheets of chrome steel, aluminum, and other non-ferrous materials.
In this process, filler metal goes to the weld through a tungsten rod, which may be a separate part from the electrode. Adding the filler metal separately makes the method very time-consuming.

Metal Inert Gas/MIG Welding Basics
One of the foremost popular sorts of welding for beginners and experts is MIG welding. It’s also the simplest sort of welding, in most people’s opinions.
MIG welding stands for Metal noble gas welding, or Gas Metal Arc Welding (GMAW). Often, the term is employed interchangeably with aluminum welding. MIG is best for joining together thinner aluminum materials.
To summarize, MIG welding is that the method for joining aluminum, steel, and other non-ferrous metals. It requires steady electricity for warmth production, an electrode for joint filling and shielding gas to guard your weld from the air.
What gas does one use for MIG welding?
As a general rule, helium and argon gases work well for metals that don’t contain iron. for instance, while aluminum welding, you’ll probably want to use argon welding gas. However, that wouldn’t work well for steel.
Sometimes people use CO2, but this will be messy. Also, it doesn’t have a reputation for producing strong welds.
Can I do MIG welding without gas?
Well, there’s a reputation for MIG welding without gas: Flux-Cored welding. (Keep reading for more info about Flux Core Welding.)
That being said, you’ll use a MIG welding to do Flux-Cored welding. Simply confirm to use a flux core wire.

Advantages & Disadvantages of MIG Welding
Like all of the methods, Metal noble gas welding has its pros and cons. By and enormous, MIG welding features a lot of benefits. First of all, it’s the simplest sort of welding process, which makes it great for beginners. It’s also the fastest method.
On the opposite hand, MIG welding doesn’t work for materials thicker than 1/18″. Also, it doesn’t add overhead or vertical welding positions.
