gázhegesztést

Gázhegesztés, also known as oxy-fuel welding or gas welding, is a fusion welding process that uses a flame produced by the combustion of a fuel gas and oxygen to melt and join metals. The most common fuel gas used is acetylene, though others like propane, hydrogen, or natural gas can also be employed. The heat generated by the flame is intense enough to melt the edges of the metal pieces being joined.

During the process, a welding torch is used to control the mixture of fuel gas and oxygen, and consequently, the flame temperature. A filler rod, made of a metal similar to the base material, is often added to the molten pool to build up the weld bead and provide additional strength. The operator moves the torch along the joint, melting the base metals and the filler rod, which then solidify to form a continuous joint.

Gázhegesztés is a versatile process that can be used on a wide range of metals, including steel, aluminum, copper, and their alloys. It is often used for repair work, fabrication of smaller components, and in situations where portability is important due to the relatively simple and self-contained nature of the equipment. The process allows for good control over the heat input, which can be advantageous for thin materials. However, it is generally slower than some other welding methods, and the heat-affected zone can be larger.
