Keevitusel

Keevitusel refers to the process of welding in Estonian. It is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the workpieces and adding a filler material to form a pool of molten material that cools to become a strong joint, with metals. Alternatively, the two materials may be pressed together with a sufficient amount of heat and pressure.

There are numerous welding methods, each with specific applications and advantages. Common types include arc welding, gas welding, resistance welding, and laser welding. Arc welding, for instance, uses an electric arc to melt the metals at the joining point. Gas welding, on the other hand, uses a fuel gas and oxygen to produce a flame that melts the materials. Resistance welding relies on the heat generated by electrical resistance to melt and fuse the materials. Laser welding utilizes a high-power laser beam to precisely melt and join components.

The choice of welding method depends on factors such as the type of materials being joined, the thickness of the materials, the required strength of the joint, and the desired aesthetic finish. Weld quality is crucial for the structural integrity and safety of the finished product, and various inspection techniques are employed to ensure that welds meet specified standards. Welding is a fundamental process in many industries, including manufacturing, construction, automotive, and aerospace.
