So, what is welding?
Welding manufacturing is when two or more parts are fused through heat, pressure, or both and then form a joint as the parts cool off.
The welded joint is referred to as a weldment.
Welding is often used on metals, but can also be used on things like wood.
The fabrication process is critical to ensure that materials are bonded together.

How It Works
You’ll typically see a torch or gun that melts a metal part at intense heat.
This process creates a molten metal pool, making joining a new metal piece easy.
Sometimes, pressure is used instead of heat, but it depends on the type and thickness of the material.

Metal: A lot of the time, heat and pressure are used over a base material. A shielding gas protects the molten metal from getting any contamination or oxidation.
Plastic welding: After surface preparation, heat and pressure are applied, and the materials are cooled at the end.
Wood: The material has to be exposed to pressure before using the same heat that the linear friction movement creates.

Types of welding process in the roll forming machine
Understanding the different types of welding can sometimes be overwhelming.
Although each type of weld has its procedure, many may fall under the same umbrella process.
Arc Welding
This uses an electric arc to create heat to melt and join metals.
A type of power supply makes an electric arc between an electrode that is consumable or non-consumable and the base material using either direct or alternating currents.
This type of welding is more of a fusion-based process and can create heat intensities up to around 6500°F.
Pipe Welding
As you may have guessed, this type of welding joins two pipes together.
A lot of the time, the specific techniques used include MIG & TIG welding.
Pipe welding relates more to metal pipes.
Often, you can find this process used in the construction industry, obviously metal fabrication shops like Dimar Manufacturing, power stations, the water industry and more.
Spot Welding
This is sometimes referred to as resistance spot welding, is used primarily for welding two or more metal sheets together by applying a particular amount of pressure and heat from an electric current to a specific weld area.
A lot of the time, low-carbon steels are used as a material with this.
Stick Welding
Also known as shielded metal arc welding, is a popular term in the industry because the electrode that welds the metal comes in the form of a stick.
The stick uses electricity to melt a metal filler rod that melts the metal joint and electrode.
Tube Welding
This is a significant and integral part of steel processing and has been around forever!
Like pipe welding, this is where two components are welded together for the part’s life. It’s often a process to create complex type structures.

It’s important always to check the quality of a weld.
Each testing procedure ensures the quality is top-notch and suitable for the weld.
NDE
NDE, also known as non-destructive evaluation, is used to look at the sophistication of welds and base metal.
It’s a simple examination and is popular because it’s a cost-effective solution.
NDE can determine material specifics compared to NDT, which we will discuss next.
NDT
NDT, also known as non-destructive testing, inspects components or different assemblies for discontinuities or an abnormality in characteristics without destroying the serviceability of the part or system.
