Problems solved by technology
[0003] In the process of electron beam fuse addition, factors such as high temperature environment, molten pool splash, and table movement will make the monitoring process difficult
The existing monitoring methods (such as camera monitoring, temperature monitoring, etc.) only solve the influence of certain factors, and the detection effect is poor; in addition, the diameter of the welding wire is small, resulting in low detection sensitivity and even difficult to monitor

Description
technical field [0001] The invention belongs to the field of electromagnetic ultrasonic monitoring, and more specifically relates to an electromagnetic ultrasonic monitoring system suitable for the manufacture of electron beam fuses. High, simple structure. Background technique [0002] Electron beam fuse additive refers to the use of computer to process the three-dimensional CAD model of the part in layers, obtain the two-dimensional profile information of the cross-section of each layer and generate the processing path, use the high energy density electron beam as the heat source, and follow the predetermined processing path , the fed wire is melted in the vacuum chamber, and piled up layer by layer, finally realizing the near-net shape direct manufacturing of dense metal parts. Significantly different from traditional removal forming and volume forming technology ideas, electron beam fuse additives respond quickly and do not require molds. Because of this, electron beam ...
