Abstract

The invention discloses a two-dimensional high-speed and high-resolution imaging system and a real-time molten pool monitoring method based on the system. The inventor divides the real-time molten pool monitoring method into two different implementation modes according to different light transmission attributes of processing materials, namely a projection type two-dimensional on-line monitoring imaging device and a reflection type two-dimensional on-line monitoring device; generally, the real-time molten pool monitoring method mainly comprises a light source assembly, a two-dimensional dispersion assembly, a modulation assembly, a focusing assembly, a filtering assembly, a circulator and a signal collection assembly. In the description of the invention, components such as laser processing equipment, laser processing parts and the like are also mentioned, so that the invention can be better described.

Description

technical field [0001] The invention relates to the technical field of high-speed imaging, in particular to a real-time molten pool monitoring technology based on a two-dimensional high-speed, high-resolution imaging system. Background technique [0002] In recent years, high-power laser processing technology has been widely used and researched, but the internal mechanism of the micro-melt pool dynamics mechanism in the interaction between high-power laser and materials has not been fully revealed. It is very prominent in the research of additive manufacturing based on laser selective melting and laser surface polishing. In the laser pinhole deep penetration welding process of thick plates, direct observation of the coupling behavior of pinholes and molten pools during the process is of great significance for in-depth analysis of the formation mechanism of weld defects. [0003] Because the molten pool phenomenon has the characteristics of high temperature and small volume,...
