Forge Welding
Mar 14, 2016

What is forge welding? Basically it's where heat is generated, usually using coal or gas as the heat source, and then the metals are joined using pressure (hammering) to bind the metals together.

Forging is also known as blacksmithing and it's very cool.

The main tool used in forging is a portable or stationary forge.

These days a portable forge is ideal for forge welding because you never know if you have to move your location. Imagine if you build a stationary or fixed location forge at your house and then you had to remodel or move. All that hard work was for not.

The good news is that a portable forge is just as good as a fixed or stationary forge, maybe better.

The main parts of a typical forge are:

Hearth - the area where the heat is generated.
Tuyere - the area that air is blown through to make the fire hotter.
Water Basin - to cool metal.
Blower - you need a blower to blow air throught the tuyere

A forge is mainly constructed out of cast iron. As described above the Tuyere directs air into the fire to make the fire more hot.

The main parts of a Forge consists of the fire pot and a base. Attached to the base will be an air inlet, an air blast valve, and ash gate.

You create an air blast using by allowing it to pass through the base using a valve. Typically an air blast valve will have 3 positions you can choose to adjust the air blast direction into the fire as well as the size of the air blast. Usually the valve has a handle with can be used to get ashes out of it.

Many portable forges have a blower that is manually operated using a hand crank. But many more have an electric blower.

Most portable forges have a hood that is designed to disperse fumes and/or smoke away from the work or basin area.

The amount of pressure a blower can produce is approximately 2 ounces per square foot.
