Problems solved by technology
The detection involves the detection of alloy elements, gas elements, organic elements and other elements. It is difficult for the existing accurate block detection technology to have such a wide range of element detection. For example, the composition spectrum detection technology commonly used in metallurgical processes can only detect metal elements. O, H, N and other elements cannot be detected
Mass spectrometers can be used to accurately detect all elements, but cannot detect bulk materials, only small particles

Embodiment Construction
[0032] In order to illustrate the present invention and / or the technical solutions in the prior art more clearly, the specific implementation manners of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention, and those skilled in the art can obtain other accompanying drawings based on these drawings and obtain other implementations.
[0033] The additive processing system of the present invention has the online detection function of spectral mass spectrometry. During the additive processing process, the spectrometer and mass spectrometer are used to detect the composition of the deposited layer in real time to determine whether the impurity components in the deposited layer exceed the standard. Once the impurity components are found to exceed the standard, stop the machine for adjustment. The additive processing system of the...

The invention discloses an additional material processing system and method with a spectrum and mass spectrometry compound online detection function. In the additional material processing process, pulse laser is used for irradiating metal at the settled layer surface, so that a settled material is gasified and ionized; a mixture containing plasmas, gas and microparticles is formed. A spectrometercollects spectral signals of plasmas for analyzing the metal ingredients and content in a settled layer; meanwhile, the mass spectrometer adsorbs gas and microparticles for analyzing the ingredient and content. The broad-spectrum precise detection on the ingredient and content of a metal material manufactured by the additional material can be realized, so that the technical support can be providedfor the quality and defect control in the additional material processing process.
Description
technical field [0001] The invention relates to the field of additive manufacturing of metal materials, in particular to an additive processing system and method with the function of combined online detection of spectrum and mass spectrometry. Background technique [0002] Additive manufacturing technology is based on a three-dimensional solid model and uses the principle of discrete stacking to realize rapid prototyping. It can directly manufacture complex structural parts of various materials, and has broad application prospects. However, the metal additive manufacturing process involves complex metallurgical processes such as metal melting and solidification, which requires extremely high purity of processed materials. Improper control of alloy composition can easily cause element segregation. Improper environmental control can also cause metals to absorb impurities such as hydrogen, oxygen, and organic matter. , These factors will lead to defects such as pores, cracks, a...
