sähköhitsausmenetelmällä

Sähköhitsausmenetelmällä, commonly translated as electric welding, refers to a group of welding processes that use electricity to create a heat source to join metals. This heat melts the base metals and often a filler material, which then fuse together as they cool, forming a strong bond. The most prevalent type of electric welding is arc welding, where an electric arc is struck between an electrode and the workpiece.

There are several variations of electric welding, each suited for different applications. Shielded Metal Arc Welding (SMAW), often called stick welding, uses a consumable electrode coated in flux. Gas Metal Arc Welding (GMAW), or MIG welding, uses a continuous wire electrode and a shielding gas to protect the weld pool. Gas Tungsten Arc Welding (GTAW), or TIG welding, uses a non-consumable tungsten electrode and a separate filler rod, offering high precision.

Electric welding is a fundamental process in numerous industries, including manufacturing, construction, automotive repair, and shipbuilding. The choice of electric welding method depends on factors such as the type and thickness of the metal being joined, the required weld quality, the welding environment, and the desired production speed. Safety precautions, such as wearing protective gear and ensuring proper ventilation, are crucial when performing electric welding due to the intense heat, bright light, and potential for harmful fumes.
