Copper Welding Techniques
Copper has been smelted by members of the human race for literally thousands of years. With its unique qualities as a metal, copper necessitates using special welding methods that you can master with the proper welding supplies from Sidney Lee Welding Supply Co in the Atlanta region.
WHAT’S THE DEAL WITH COPPER?
Copper is a highly conductive metal and thus cools very fast. Because of this factor, copper welding requires the correct use of welding gas. In particular the shielding gas must allow for constant flow of high heat so that the metal does not cool mid-weld. For this reason, welding copper can become rather an expensive undertaking, since the best welding gas in this case is helium—not a cheap kind of gas. Argon gases may also be used, however they produce about one third of the amperage than helium. So another solution for the budget-conscious would-be welder of copper is to use mixed gases. Such a decision will hinge on the kind of welding equipment in your arsenal: how powerful is your machine? With the right kind of Miller welder such as a TIG or shielded metal arc welding machine, you can probably work with argon gases if the copper workpiece is thin enough.
GOT THE GEAR, WHAT’S NEXT?
As for the actual technique to employ once you have the right welding supplies on hand, it depends, as always, on the type of welding project you’ve got before you. When dealing with thin sheets of copper less than a quarter inch of thickness, rely on the forehand technique. For extra thin sheets half that size, make use of butt joints, while for thicker pieces of copper take advantage of your best backhand technique.
Remember, the trick to welding copper is to be quick about it. If your weld keeps going faster than the metal can cool, you can stay on top of the project without needing to upgrade your shielding gas supply.
