Welding Heating Torch

A welding heating torch is a tool used to heat metal before welding. The torch uses a flame to heat the metal, which helps to expand it, making it easier to weld. It's also used to preheat the metal to prevent cracking or warping during the welding process.

There are different types of welding heating torches, but most consist of a handle with a trigger or valve to control the flame, and a tip that produces the flame. The tip is usually made of copper and has a small opening through which the fuel and oxygen are mixed to create the flame.

The type of fuel used in a welding heating torch can vary, with propane and acetylene being the most common. Acetylene is considered the hottest burning fuel, making it ideal for heating large areas of metal quickly. It's important to use the correct fuel and tip size for the metal and application you're working on, to avoid overheating and warping the metal.

In addition to preheating, heating torches are also used in brazing, soldering, and heating frozen pipes or metal surfaces.
