Abstract

The invention provides a laser additive device which comprises a rotary light beam laser system, a high-frequency short pulse laser system and an auxiliary current system. The rotary light beam lasersystem outputs rotary continuous laser light, and the continuous laser light is used for melting and depositing wires to the surface of a base material; the high-frequency short pulse laser system outputs high-frequency short pulse laser light, and the high-frequency short pulse laser light is used for inputting a pulse laser beam into a molten bath. The auxiliary current system is used for enabling the wires and the molten bath to form a current loop, and therefore strong electromagnetic force is directly produced in the molten bath. The rotary light beam laser system comprises a continuous laser generator, a first high precision mechanical arm and a continuous laser device laser head. The high-frequency short pulse laser system comprises a high-frequency short pulse laser generator, a high-frequency short pulse laser head and a second high precision mechanical arm. The defects that element segregation is likely to be caused in the molten bath, gas cannot be exhausted, the structure is uneven, and heat stress is concentrated can be overcome.

Description

technical field [0001] The invention relates to the technical field of laser additive manufacturing, in particular to a laser additive manufacturing device and a method for additive manufacturing thereof. Background technique [0002] Additive manufacturing technology, also known as 3D printing technology, has attracted the attention of many scholars in recent years and is called "the third industrial revolution". Among many additive manufacturing methods, laser additive manufacturing (LAM) is a relatively advanced manufacturing method for preparing net-shape metal components with excellent performance. It has been widely used in automobiles, aerospace, military equipment and medical treatment. . At present, many scholars at home and abroad have made great progress in the research field of laser additive manufacturing technology. Using this technology, alloy components of nickel-based alloys, titanium alloys, stainless steel and other materials with good performance have be...
