Your question: Can you forge weld with charcoal?

I use charcoal primarily for bladesmithing and sometimes weld in it too. Your suspicion about having too much air in the fire is probably right. … A good way to go is to have a 6″ or so fire, lots of flux, moving quick, and DON’T try to do it all in one heat. Setting the weld and re-heating isn’t a bad idea.

Can charcoal be used in a forge?

Charcoal is considered the least desirable fuel when blacksmithing. While readily available, charcoal may not even reach the necessary temperature to soften iron and steel without a lot of fuel and constant airflow. You can burn through a lot of charcoal quickly and still not achieve the proper temperatures.

Can you forge with lump charcoal?

Lump Charcoal As A Fuel Source For A Blacksmithing Forge

So as I mentioned earlier, lump charcoal is what people typically mean when they mention charcoal for smithing. Lump charcoal burns longer, hotter, and cleaner than wood.

How hot will a charcoal forge get?

According to “Marks’ Standard Handbook for Mechanical Engineers”, 10th, coal gas burns at about 3,590°F (1,977°C) under 100% air conditions. More or less air will decrease the temperature. This means that the maximum temperature of a coal fire in a forge is about 3,500°F (1,927°C).

Can you forge weld mild steel?

When the right temp, mild steel can forge weld without any flux. You can also, if using something like borax or sand for your flux, add some powdered iron to the flux which can help the weld.

What burns hotter charcoal or wood?

Charcoal has an energy value of around 29 MJ/kg, in other words charcoal burns hotter than wood, but when not insulated or not receiving sufficient air supply (including secondary air), the absence of flames or fast flowing CO2 gases will result in less efficient cooking due to a lower heat transfer efficiency (HTE).

What is the best fuel for a forge?


Can you forge steel with a wood fire?

With a regular wood fire you won’t be able to get the steel hot enough, probably no more than 900 degrees. you can use the wood to make charcaol if lack of coal is the problem.

Does Coke burn hotter than coal?

Coal is a shiny, black fossil fuel that contains impurities, emits smoke when burned, and produces less heat than coke. Coke is a dull, black byproduct of coal that burns hotter and cleaner. … However, blacksmiths still rely on coke as an efficient source of fuel for the forge.

What is the hottest Forge?

The hot forging manufacturing process is performed at extreme high temperature (up to 1150 °C for steel, 360 to 520 °C for al-alloys, 700 to 800 °C for cu-alloys).

Can you melt steel with charcoal?

The easiest way to melt metal into liquid is to heat it in a small, enclosed vessel that is heated from below. You can make your own using a small empty propane tank or metal bucket, plaster of paris, sand, metal pipe, charcoal briquettes, and a steel can.

At what temperature can you forge steel?

If the temperature of the steel is too high, then “burning,” or incipient grain boundary melting, of the steel can occur. While typical hot forging temperatures are between 2150°F and 2375°F – well below the melting temperature of more than 2500°F – deformation (adiabatic) heating results in local heating.

Can you forge weld without flux?

Speaking of flux- several folks have been doing good forge welds with NO FLUX, just the proper welding temp. … Sure be nice not to have to reline my forge after the flux eats the guts out :) You may want to give it a try, too.

Do you need flux to forge weld?

In order to take the mystery out of forge welding you must realize that flux may not be required, but it does, in most cases, make it easier.
