Abstract

The invention discloses a device and method of laser impact welding in a warm state. The device comprises a laser emitting system, a control system and a workpiece warm welding operation system. The workpiece warm welding operation system comprises a workpiece warm device, a base plate pressing device and a workpiece pressing device. Before-welding preheating of a workpiece is achieved through the workpiece warm device, the plasticity of the to-be-welded workpiece is improved, and the welding performance of the workpiece is improved; by means of the base plate pressing device and the workpiece pressing device, the precise clamping of the workpiece in the warm state is achieved. The device is high in precision and automation degree and wire in application range, and warm welding of various different materials can be conducted.

Description

technical field [0001] The invention relates to the field of laser shock welding, in particular to a device and method for laser shock welding in a warm state. Background technique [0002] In recent years, with the rapid development of electronic products, biology, medical equipment, precision instruments, sensors and other industries, the miniaturization, precision and high performance of products have become one of the important trends in the development of the manufacturing industry, and related micro devices The research of welding technology becomes more and more important. The performance requirements of micro-devices are getting higher and higher. It is difficult for a single material to meet the needs of industrial production, or a material with ideal performance cannot be widely used in industrial production because of its scarcity. Therefore, the connection of dissimilar materials is an inevitable trend. Laser shock welding is a relatively new high-speed shock we...
