Can You Forge Weld In a Gas Forge? – [The Fact]

forge welding in a gas forge

Most of the metal reshaping and welding begins in a Coal forge. Since the bronze age, the fundamental process of forge hasn’t changed, but it gets a lot easier.

A gas forge, in particular, solves a lot of problems, which makes metal work much more beginner-friendly.

Can you forge weld in a gas forge? As far as the gas forge goes, it is very much capable of producing heat to weld metals. Regardless of the quiet nature and fuel availability, it has a limitation on how big of a workpiece you can heat up depending on the container size.

The great advantage of gas forge would be the portability and quick heating up characteristic. Also, not to mention the lack of any physical effort that you have to endure in traditional forge.

Within minutes you can bring your billet or metal to welding temperature.

Starting metalwork with a traditional forge often poses many difficulties like smoke, loud noises, and potential fire hazard. In a residential area, that’s pretty concerning.

On top of that, sourcing coal for the forge is hard nowadays and not so eco-friendly.

A situation like this always demands an alternative solution. Here Gas forges play like a champion without taking much of your workspace. Whether you are into blade making or tools making, this will increase productivity.


While gas forge has tons of features, it doesn’t come entirely free of drawbacks. You cannot heat larger metal pieces, and for some heavy metal, it may not be an ideal option. You will still get oxidation in the gas forge due to air coming through a choke point.

All things considered, the gas forge will be a perfect choice for you in pursuit of a successful blacksmith career.

What is forge welding?

Forge welding is a traditional way to merge two or multiple metal objects. The process involves heating the metal and pounding with a hammer until it becomes a single object.

Since the middle ages, it has been the most prominent method of joining metals to construct bigger pieces.

Whether you are just starting or have done some metalworking in the past, forge welding is an essential skill to learn. With time you will gain invaluable experience to do it effectively and efficiently.

How strong is a forge weld?

Although forge weld strength comes out strong as the parent metal, a lot depends on the skilful work. Forge welding is a rapid process, if done right you can achieve 80-90 percent strength of the base metal.

From the old days, blacksmiths were making chains and ship’s anchors following the same forge welding process. So you can say it’s pretty strong and ideal for most practical purposes to this date.

Can you forge weld copper?

Unlike iron and steel, copper isn’t much of a fan of forge welding. You can technically forge weld copper alloys, but it’s not worth the hassle.

The reason copper doesn’t stick well when heated, it tends to introduce oxygens into the seeming, which prevents good welding.

Even if you manage to weld two copper bars together, there will be cracks and gaps between them. This will later jeopardize the structural integrity that takes out the practical properties.

Can you forge weld copper to steel?

It’s possible to weld copper to steel but don’t expect a smooth finish like steel welding. There will be fractures in the weld due to copper contamination, which is never a good sign in forge welding.

The quality of welding will depend on the skill of the blacksmith as copper is a much softer metal than steel. Needless to say, the copper will melt if you overheat it.

So be mindful of the welding temperature between steel and copper.

Can you forge weld stainless steel?

Yes! You can. If you forge weld stainless steel, the existing property of the material will significantly increase, such as rust and heat resistance.

Therefore, it will be more robust and long-lasting regardless of the heavy use.

One thing to keep in mind, that forging stainless steel does require a higher temperature than any other carbon steel.

Using proper Gas forge can be helpful in this case to heat the metal rapidly and eliminate oxidation while welding.

Can you forge weld stainless steel and carbon steel together?

It’s possible to forge weld stainless steel and carbon steel into a single object. Though, you will need appropriate forge welding equipment and precession skill to pull the perfect bond.

A controlled environment and hand-eye coordination will also come in handy for this operation.

Stainless steel and carbon steel have wide use in tools and equipment because of their anti-rust and strength properties. One way to combine those properties is to forge them together.

That way, you will have durability and rust-free material to work with.

Can you forge weld Damascus?

If you have the right blacksmith hammer and two different types of steel, it’s easy to forge weld modern Damascus steel.

In addition to that, other forging tools like a flat anvil, blacksmith tongs, and well-contained gas forge will play a significant role in achieving quality results.

Damascus is popular for its beautiful pattern, strength, and resilience. You can simply achieve this by combining metals with dissimilar carbon content stacking up on top of another.

Once you forge weld the pieces, etching will reveal the distinct pattern.

What temperature do you forge weld Damascus at?

The ideal temperature to forge weld Damascus would be in the 800-1200 Celsius range. Due to the carbon content in the metal, it widely varies.

Another good indication of the temperature would be 50-80 percent of the melting temperature of that particular metal.

Bright orange is the color tone you would want for a perfect weld. Remember not to overheat the metal to the point it glows bright yellow.

You will lose more metal due to the scaling process and form micro-fracture between the plates.

Can you forge weld without a power hammer?

As long as you are forge welding small metal pieces, a pair of blacksmith’s hammers is all you need.

But if your workpieces are large and you alone doing all the work, it can be difficult. The power hammer takes out the struggles and makes the forge welding process much easier.

Since forge welding is a very rapid process, it will only get intense as the work metal gets bigger and bigger. The pressure of pounding will also increase along with the size.

At that point, a mere hammer could not produce enough pounding pressure to weld.
