Welding is the foundation of metal fabrication and a crucial process in any industry. This results in a bond between various metal objects that is so strong and lasting (allowing all those skyscrapers, on down to fine medical instruments-and some crude ones we would wish did not exist- their strength and life).

Welcome to Welding for Manufacturing – a post that takes us down among the weeds with an in-depth look at how welding can be used across manufacturing applications. This time we will dive into the different welding techniques, what they are good at (and bad!), and where you might use each technique. Knowing these techniques also makes you appreciate even more the craftsmanship and technology that goes into using many of the products we see every day.
Common Welding Processes in Manufacturing
The welding world is a large one with a growing number of techniques that are available to people. In this post, we will cover some of the more common welding processes used in manufacturing:
Arc Welding: The Arc welding process utilizes an electric arc to create the heat that melts and joins metals at a joint. Arc welding is repeatable and can be highly automated on production lines. Popular variations include:
MIG (Metal Inert Gas) Welding: MIG welding is a fast, easy and clean way to join two pieces of thin metal together with just one pass. It is heavily employed in the automotive manufacturing and sheet metal fabrication industry.
Tungsten Inert Gas (TIG) Welding – This type of welding uses a non-consumable tungsten electrode with inert gas shielding. I find TIG welding to be incredibly versatile, because you can control all aspects of the weld very well and it usually results in a nice clean weld. That makes it popular for thin metals and products that need a crisp finish like aerospace or medical devices.
Stick Welding: the other name is Shielded Metal Arc Welding (SMAW) known as it uses a consumable electrode with an effective flux coating. Not as accurate as MIG or TIG, stick welding provides a deeper penetration which makes it ideal for field work and dirty/rusty metals.
Resistance welding: In this process, a weld is formed in the contact point between two pieces of metal using pressure and electrical current. Resistance welding provides quick operations and it is rapid processing, convenient in modern assembly lines. Two prominent types include:
Spot Welding: Such welds are formed locally through the two electrodes which apply pressure on metal sheets. Spot welding is often used in the automotive manufacturing process for joining body panels together.
Seam Welding – Probably the simplest of them all, seam welding literally consists in creating a consistent weld over the length o f an overlapping joint It is widely used for manufacturing tanks, pipes and other cylindrical shapes.
Laser welding: Joining with a laser beam that is very fine in width and high power density to melt metal. Laser welding is very precise, and deep penetrating with low heat distortion. This makes it ideally suited to use in applications that require high strength, accuracy and the ability to join dissimilar metals- such as those found within aerospace or medical device manufacturing.
Other Welding Processes: Particular type of manufacturing processes make use of a few extra welding techniques that are as follows.
BrazingUse of a filler metal with both the base and ceramic, which has a lower melting point than that of those metals. Brazing typically has high mechanical strength, but it is not as strong in resistance to tensile and shear loads as a properly executed weld.
Soldering: Solder is a filler metal having very low melting point and which produces much weaker but inexpensive connections. Frequently used in Electrical connections and industries for Electronics manufacturing.
Selecting a Weld Process That Best Fits Your Needs
When a manufacturer is choosing the most suitable welding process for their particular application, it will depend on several aspects of that business like:
Thickness of Material: Some processes favor thin metals, while others prefer heavy. For instance, MIG welding is great for thin sheets while sticking to the thicker plates.For instance, the type of joint (butt join, lap seam etc.) when it comes time for making changes to your process choice. Others, such as TIG welding are used for complex joint configurations with greater control.
We all know, for the kind of application we are preparing our material and welding and desired strength from weld. Laser welding, in which very strong welds for critical components are made.
If you are working in high volumes, production speed and whether or not the machine can be easily automated to work as an automatic butt welder will become extremely important. Because of this, many people chose MIG welding over the other options as it is quick and somewhat automated.
Cost – Different equipment will have different upfront costs, but consumables and labor expertise can also be factored in when discussing the total cost of welding as well.

As we know, welding is versatile enough for a wide range of manufacturing sectors. For your seeking, I presented some examples below.
The Purchase of a Car: Welding is the most important element in automotive production because it allows us to manufacture car frames and body panels, exhaust systems,and engine components all rely on it. 4. For speed and efficacy, MIG welding or spotting are commonly used.
Aviation sector– Airplanes need to be made with a light and strong structure. The most part laser welding and TIG welding are capable of low heat-input – Titanium & aluminum for higher strength alloys.
