Hitsauskoneella, often referred to as a welding machine, is an electrical device used to join metal parts together by melting them. The process involves heating the metals to their melting point and then allowing them to cool and solidify, creating a strong bond. There are various types of welding machines, each utilizing different methods to achieve the heat required for welding.

Common types include arc welding machines, such as Stick (SMAW), MIG (GMAW), and TIG (GTAW). Stick welding uses a consumable electrode coated in flux, which provides shielding gas and slag to protect the weld pool. MIG welding uses a continuous wire electrode fed through a welding gun, along with a shielding gas. TIG welding uses a non-consumable tungsten electrode and a separate filler material, offering precise control and high-quality welds.

Other welding methods employ different principles. Gas welding uses a flame produced by burning a fuel gas, typically acetylene, mixed with oxygen. Resistance welding, like spot welding, uses electrical resistance and pressure to heat and fuse metals at specific points.

The selection of a welding machine depends on the type of metal being joined, the thickness of the materials, the desired weld quality, and the application's specific requirements. Safety is paramount when operating a welding machine, as it involves high temperatures, electricity, and potentially hazardous fumes. Proper personal protective equipment, such as welding helmets, gloves, and protective clothing, is essential.
