Danox Welding - What are the different types of Welding?
Working with heavy-duty metals and the process of 'welding' can be intimidating to many individuals, but it can also be empowering to some. Having the capability to transform some of the world's strongest materials into different shapes and amazing products!
Furthermore, with the advent of technologies today, the process of welding had changed and evolved over the years. Thus, it is incredibly essential to understand the differences between all the existing welding techniques in order to make the right decision of using the right welding technique or process for the right job.
Despite the fact that many processes can be done using automated equipment, you would still require professional help from steel fabricating experts to accomplish a customised product. Hence, Danox Welding Pte Ltd is here today to share with you the different types of welding process that are commonly used in the industry. Allowing you to gain a better understanding of the industry, the welding products and equipment that we are providing at Danox!
If you’re a beginner and looking to learn the basics, you’ve come to the right place!
Without further ado, let's begin!
Introduction to Welding
Before taking a look at the different types of the welding process, let us proceed on learning about what exactly is 'welding'?
Welding is the process of fusing materials such as metals or thermoplastics to join them seamlessly. The welding process involves applying heat and pressure to the materials being combined, in addition to the filter material.
4 Different Types of Welding
1. MIG Welding or GMAW Welding
2. TIG Welding or GTAW Welding
3. Stick Welding or SMAW Welding
4. Arc Welding or FCAW Welding
1. MIG (Metal Inert Gas) Welding or GMAW (Gas Metal Arc Welding):
The concept of combining two pieces of metal together with a wire that is connected to an electrode current is referred to as Metal Inert Gas (MIG) welding. In this type of welding process, a shielded gas is used along the wire electrode, which heats up the two metals to be joined. A constant voltage and direct current power source are required for this method, and this is the most common industrial welding process. The MIG or GMAW process is suitable for fusing mild steel, stainless steel as well as aluminium.
What can MIG Welding be used for?
It should be said that MIG welding can be applied in various situations. A good MIG welder should be able to weld both thick and thin sheets of metal. Quality machines have a wide power output range and a gauge that will let you adjust the power, allowing you to approach softer material without fear of burning through it. At the same time, they’re still powerful enough to weld thick steel pipes and provide a secure connection.
2. TIG (Tungsten Inert Gas) or GTAW (Gas Tungsten Arc Welding):
A non-consumable tungsten electrode is used in this type of welding process. This tungsten electrode is made use of to heat the base metal and create a molten weld puddle. By melting two pieces of metal together, an autogenous weld can be created.
For this type of welding, the welder needs to have a lot of expertise as it’s a very complicated process. This welding process is employed to carry out high-quality work when a superior standard finish is required, without making use of the excessive clean up by sanding or grinding.
What can TIG Welding be used for?
Just like GMAW, GTAW welding can also be applied to many materials. However, the thickness range of this welding type is more limited. Though you can weld both steel and aluminium with the same ease, the materials you will be welding are going to be thinner. The tungsten rod is much thinner than a stick rod, allowing you to make more precise but much thinner welds.
3. Stick or SMAW (Shielded Metal Arc Welding):
Arc welding is also called as Shielded Metal Arc welding or simply referred to as ‘Stick’. This is the most basic of all welding types. The welding stick uses electric current to form an electric arc between the stick and the metals to be joined. To weld iron and steel, this type of welding is often used in the construction of steel structures and in industrial fabrication. Stick welding can be used for manufacturing, construction and repair work.
What can TIG Welding be used for?
Stick welding is a type of arc welding and is widely used in construction because of the incredible strength of this weld. It's the way to go for thick materials, including cast iron - which can be tough or impossible for other welding types. But when you want to have two pieces of thick metal fused together, and to make sure the weld is going to last, this is the way to go.
4. Arc Welding or FCAW (Flux-Cored Arc Welding):
As an alternative to shield welding, Flux-cored Arc Welding was developed. This welding process is quite similar to MIG or GMAW process, except for the fact that in FCAW a special tubular wire filled with flux is used and shielding gas is not always needed, depending on the filler. This type of welding is well-known for being extremely inexpensive and easy to learn. However, there are several limitations in its applications, and the results are not often aesthetically pleasing as some of the other welding methods. The semi-automatic arc is commonly used in construction projects, thanks to its high welding speed and portability.
What can Arc Welding be used for?
When using Arc welding or flux-cored welding style, you will want to use it with more massive and thicker materials. Flux-cored welding also creates a lot of heat, and you will want to use it where there is enough metal to withstand that much heat. This type is used mainly for heavy steel construction and erection, heavy repairs and heavy machinery and other such equipment.
