Whether you use a small or large tank for your gas welding, we have a solution for you. The regulator acts as a barrier between the high pressure inside the tank and the low pressure of the ambient air. Burn Time. Gas welding, arc welding, and resistance welding all appeared at the end of the 19th century. Safe and cost effective if you already have a natural gas hookup, but requires a professional to install. The temperatures below are measured in an argon arc, at a welding current of 150 amperes and with a 2.4 mm tungsten electrode with a top angle of 60 degrees. The combustible gases used in gas welding include acetylene, methane, liquefied petroleum gas, etc. Since Tungsten has a melting point of approximately 3400 °C, it is harder to melt than most metals; it is nonconsumable or would not melt in the arc. It is suggested that the maximum interpass temperature be 200°F (93°C). … You can also read a text description of this information below. Advances in Welding Science & Technology, S.A. David, ed., ASM International, Metals Park, OH, 291, 1986. When the psi is low and the gas flow rate is sporadic, it causes pin holing and spattering in your weld joints. Whether you refer to it as oxy-fuel welding, oxy welding, or simply gas welding, it doesn’t come without its challenges. Cold temperatures can cause gases to liquefy and settle at the bottom of a cylinder.
