Compressed propane is extremely flammable, and the resulting flashback could cause an explosion.īefore you continue reading, here is an article we wrote about welding with a sparkler. Note: Do NOT attempt to ignite a propane blowtorch with a butane lighter. How to weld with a propane torch? It is easier to weld with a propane torch than it is with a butane torch, though a propane torch is still only suitable for certain types of braze weldings, such as silver solder or brass brazing.Ī propane torch doesn’t reach high enough temperatures suitable for welding through fusion. You have to keep in mind that 90% of a blowtorch’s heat is dissipated through contact with the air, which makes it one of the least efficient welding methods without a shield.

No, butane torches do not reach a high enough level of heat and energy to be able to braze or weld metals efficiently.Ī butane blowtorch simply does not get hot enough to affect the metal. Electric welding usually achieves a more stable weld with joints that require a high degree of structural integrity.ĭespite these marks against them, blowtorches can and are still commonly used in metal fabrication for a variety of different projects and applications.Some propane torches can reach temperatures capable of brazing or soldering brass and silver, but many blowtorches that are commonly found in home utility kits do not generate a high enough heat for welding.Many commonly found utility blowtorches are not powerful enough to melt metals like steel.There are several common kinds of welding, with tools ranging from handheld arc welding torches to industrial-grade furnace welders that braze every joint on an assembly in one go.īut many people don’t think of blowtorches when it comes to welding for a few reasons: Is A Propane Torch Hot Enough To Braze?.Blowtorches are Primarily Designed for Cutting Metal, not Welding.What Is The Best Torch For Soldering Copper Pipe?.Can You Weld Stainless Steel with a Blowtorch?.
