How much psi do I need for a forge burner?

The burners can run efficiently across a pressure range of 3- 20 PSI.

How far apart should my forge burners be?

On a multiple burner atmospheric gas forge using side arm burners what do you recommend the spacing to be between the burners? A. I recommend the burners to be 3 1/2″ to 4″ on center and no more, this will insure that you get an even heat on your pieces of metal that you are heating.

What is forge welding temp?

Pure iron can be welded when nearly white hot; between 2,500 °F (1,400 °C) and 2,700 °F (1,500 °C). Steel with a carbon content of 2.0\% can be welded when orangish-yellow, between 1,700 °F (900 °C) and 2,000 °F (1,100 °C). Common steel, between 0.2 and 0.8\% carbon, is typically welded at a bright yellow heat.

How long does it take to heat up metal in a forge?

Both the ASM Metals Handbook and ASM’s Forming and Forging Handbook state that “for stock up to 3 in. in diameter, the heating time per inch of section thickness should be no more than 5 minutes for low-carbon and mediumcarbon steels, or more than 6 minutes for low-alloy steels.

What gas should I use for my forge?

Propane is very easily obtained and has the advantage of being portable, cleaner, and hotter than coal and charcoal. If you own a propane torch, you can just use that to heat metal. If you plan to do a lot of smithing or building, purchasing a propane forge will become a consideration.

What is the difference in an atmospheric burner and a forced air burner?

What’s the Difference? An atmospheric burner uses the natural process of gas escaping from the orifice to mix with primary air. A power burner forces air in with a mechanical blower and is therefore able to mix with greater amounts of gas while sustaining the required gas: air mix ratio.

Can you use natural gas for a forge?

Hi-pressure natural gas is the right fuel for your forge ! Best of all, for equal heat performance natural gas costs a lot less than propane. Contact G-TEC at 800-451-8294 to discuss the right Torch Booster if you plan supply pressure greater than 8 psi to your forge.

What do you line a propane forge with?

The bottom of the forge needs to be lined with fire brick. The firebrick is a durable floor material and can be replaced if you do any amount of forge welding as the flux will eat away at the brick.

Do you need flux to forge weld?

Blacksmith flux is used to reduce the temperature at which the surface elements (scale, impurities, etc.) In order to take the mystery out of forge welding you must realize that blacksmiths flux may not be required, but it does, in most cases, make it easier.

Can I use borax to forge weld?

Borax is used as a flux when forge welding to prevent oxidation of your surface and weld. The best type of borax to use is generally anhydrous borax (Amazon affiliate link), as it speeds up the process due to its early liquefaction, and leaves little room for impurities to get inside the joints in your weld.
