Laser shock welding device with shock angle continuously adjustable under vacuum environment

Abstract

The invention provides a laser shock welding device with the shock angle continuously adjustable under a vacuum environment. The device comprises a computer control system, a laser generating system, a vacuum system and a clamp, wherein the clamp is located in a vacuum chamber and fixed on the bottom surface of the vacuum chamber, the clamp comprises a horizontal working platform with the vertical position adjustable and an inclined working platform with the inclining angle adjustable, the laser generating system is connected with the vacuum chamber through a light path, and the laser generating system and the vacuum system are both connected with the computer control system. According to the device, continuous adjustment of the shock angle is achieved during laser shock welding, resistance of the atmosphere to an ultra-thin composite plate material under the high-speed shock condition is eliminated, and welding performance is effectively improved.

Description

technical field [0001] The invention belongs to the field of welding, in particular to a laser impact welding device with continuously adjustable impact angle in a vacuum environment. Background technique [0002] Laser shock welding machine is an emerging material welding technology under high-speed impact conditions, which can realize spot welding between the same and dissimilar materials. Its advantage is that there is no heat-affected zone after welding, so the welded materials can maintain even Higher than the performance of the base metal, it will not weaken the strength of the welded joint like fusion welding or cause cracks, rust and other problems due to the residual stress in the welded area. This emerging patent No. US8084710 (B2) patent Low-temperature laser spot impact welding without contact was first proposed a high-speed impact welding method, the principle is that the laser irradiates the opaque coating into high-temperature and high-pressure plasma, The sh...
