Lánghegesztésre

Lánghegesztésre, commonly translated as oxy-fuel welding or gas welding, is a fusion welding process that uses a fuel gas, usually acetylene, and oxygen to produce a flame. This flame heats the base metals to their melting point. Filler metal is often added to the molten pool to create a stronger joint. The process is versatile and can be used for joining a variety of metals, including steel, aluminum, and copper alloys.

The equipment for lánghegesztésre typically includes gas cylinders for fuel gas and oxygen, pressure regulators, hoses, and a welding torch. The torch mixes the gases in specific ratios to create a controlled flame, which can be adjusted for different applications. Different types of flames exist, such as a neutral flame, an oxidizing flame, and a carburizing flame, each having distinct properties and uses.

Lánghegesztésre is known for its portability and relatively low cost of equipment, making it suitable for repair work, small-scale fabrication, and applications where electricity is not readily available. It can also be used for brazing, cutting, and heating. However, compared to other welding processes like arc welding, it generally has a lower welding speed and can produce a wider heat-affected zone, which may affect the material properties. Safety precautions are crucial due to the open flame and flammable gases involved.
