Document Type and Number:
WIPO Patent Application WO/2024/087256
Kind Code:
A1
Abstract:
The present invention relates to the technical field of material processing engineering. Disclosed is an ultrafast laser scanning assisted micro-casting and forging integrated welding method, comprising the following steps: step 1, preparing a liquid metal in a melt crucible; step 2, setting the heating temperature of a flow guide pipe; step 3, calculating the amount of the liquid metal that needs to be filled within a unit time; step 4, setting a distance between a micro-forging area and a liquid metal outflow area; step 5, designing the swing mode, swing amplitude, swing frequency and laser power of ultrafast laser scanning, and meanwhile, setting the flow rate of a protective gas; step 6, checking whether the working state of a device is good; step 7, respectively setting starting and stopping signals when the welding trajectories of a crucible system, an ultrafast laser assistance system, and a micro-forging system change, the starting and stopping signals of the crucible system and the ultrafast laser assistance system being at a same position; and step 8, starting the device to start welding. The present invention can ensure that a substrate and a delivered liquid metal are effectively fused into a whole, and achieves efficient and high-quality welding.
