welding definition and clasification

welding
Welding - obtaining one - piece compounds by establishing interatomic bonds between the joined parts when they are heated and (or) plastic deformation.   Metal welding - the technological process of connecting the metal (s) with such heating and / or pressure, as a result of which the continuity of the structure of the connected metal (s) is obtained. Notes Can be used or not used filler metal , the melting point of which is of the same order as that of the base metal (s); the result of welding is a welded joint . This definition also includes surfacing . By the term: fusion welding ; pressure welding ; welded construction . METAL WELDING CLASSIFICATION "Welding of metals. Classification" , welding of metals are classified according to three main characteristics : ph

Drone Definition A drone, in technological terms, is an unmanned aircraft. Drones are more formally known as unmanned aerial vehicles (UAVs) or unmanned aircraft systems (UASes). Essentially, a drone is a flying robot that can be remotely controlled or fly autonomously through software-controlled flight plans in their embedded systems, working in conjunction with onboard sensors and GPS. Drone is a broad term that can refer to any unmanned aircraft. However, it usually refers to a multirotor. A multirotor has three or more propellers that can be used to hover or fly in any direction. The most common type is a quadcopter, which has four propellers Drone Training program General UAV theory (6 hours) UAV History and Prospects General theory Aeronautical meteorology Air na...
