Friktsioonkeevitus
Friktsioonkeevitus, also known as friction welding, is a solid-state joining process that utilizes the heat generated by friction between two surfaces to achieve a weld. In this method, one of the workpieces is rotated at high speed against a stationary or similarly rotating second workpiece. The intense friction between the surfaces causes them to soften and become plasticized, allowing for a metallurgical bond to form when pressure is applied.
The process typically involves three main stages: initial contact and friction heating, material displacement and consolidation,
Friction welding is a versatile technique capable of joining a wide range of dissimilar metals and alloys
