Introduction

The use of lasers as tools in manufacturing has brought about a series of changes, and the understanding and control of light is the key to realizing the industrialization of laser manufacturing. key premise. High-power laser manufacturing equipment is the core of the laser manufacturing field, and its laser safety is an important link that cannot be ignored. through the pair Related standards developed by standardization organizations such as the International Electrotechnical Commission (IEC), the International Organization for Standardization (ISO), and the American National Standards Institute (ANSI). Standard research, in terms of laser hazard assessment, safety classification and control measures, relevant standards have reached international consensus. There are differences and connections between this document and GB/T 18490.1-2017 and GB/T 7247.5-2019.These two standards regulate what to do If so, this document provides guidance and advice on what to do. The calculations involving the safety classification of laser products in this document are performed in accordance with the relevant provisions of GB 7247.1-2012; The calculation of the emission MPE value and the relevant parameters based on the MPE value shall be performed in accordance with the relevant provisions of ANSI Z136.1-2014. This document is expected to contribute to the standardized management and improvement of quality and efficiency of the use of high-power laser manufacturing equipment. When encountering problems, take responsibility The determination is clear, the source can be traced from the top, the bottom can be traced from the bottom, and there is evidence to exempt liability. Safety and Use Guidelines for High Power Laser Manufacturing Equipment
