What are welding blowpipes used for?

Welding blowpipes, commonly known as oxy-fuel welding torches, are used to produce a high-temperature flame by mixing oxygen and a fuel gas, typically acetylene. This flame is utilized for welding, cutting, and brazing metals by melting the base materials and allowing them to fuse together. Additionally, blowpipes can be employed in various applications, including metal shaping and heating. Their versatility makes them essential tools in metalworking and fabrication industries.
