Zváranie

Zváranie is the Slovak word for welding. Welding is a fabrication process that joins materials, usually metals or thermoplastics, by using high heat to melt the parts together and allowing them to cool, causing fusion. This process is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal.

In many cases, a filler material is added to the joint to form a pool of molten material that cools to form a strong joint, known as a weld. The weld can be made stronger than the base material, or weaker, depending on the specific application. Pressure may also be used in welding, along with or instead of heat.

There are many different types of welding processes, each with its own advantages and disadvantages. Some common types include arc welding, gas welding, resistance welding, and solid-state welding. Arc welding uses an electric arc to create heat, while gas welding uses a flame. Resistance welding uses electrical resistance to generate heat, and solid-state welding joins materials without melting them, often through pressure.

Welding is a crucial process in many industries, including construction, manufacturing, automotive, shipbuilding, and aerospace. It is used to create everything from bridges and buildings to cars and airplanes. The specific welding technique used depends on the materials being joined, the required strength of the joint, and the environment in which the welding is performed. Safety is a paramount concern in welding due to the high temperatures, UV radiation, and potential for hazardous fumes.
