Embodiment Construction

[0024] The present invention provides a method and equipment for removing plasma clouds. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] A preferred embodiment of a device for removing plasma clouds of the present invention includes a control host 1 and an induction coil 2 positioned above the plasma clouds, such as image 3 As shown, the control host is electrically connected to the induction coil, and the control host controls the induction coil to generate an alternating magnetic field for removing the plasma cloud.

[0026] In a plasma cloud, the direction of ion motion is random, so there is a half-possibility of moving outward. After increasing the magnetic field, the magnetic field distrib...

Abstract

The invention discloses a method and device for removing a plasma cloud. The device comprises a control host and an induction coil which is electrically connected with the control host; the inductioncoil is located over the plasma cloud; and the control host controls the induction coil to generate an alternating magnetic field used for removing the plasma cloud. The device not only can rapidly remove the plasma cloud generated during laser processing, but also can improve the quality of liquid metal crystallization.

Description

technical field [0001] The invention relates to the field of laser processing, in particular to a method and equipment for removing plasma clouds. Background technique [0002] In the field of laser processing, especially in the process of high-power laser processing, such as welding and blind hole drilling, plasma clouds will be formed inside and above the molten pool, such as figure 1 As shown, the plasma cloud affects the laser absorption, thereby reducing the liquid metal forming efficiency. In order to solve the above problems, in the existing laser processing technology, the gas side blowing method is used to remove the plasma cloud, such as figure 2 shown. But in this way, if the injected gas is directly facing the surface of the liquid metal in the molten pool, it will affect the formation of the liquid metal. If it is only blown sideways on the surface of the liquid metal in the molten pool, the plasma cloud inside the molten pool cannot be quickly removed. [0...
