Abstract

A laser operating method, comprising: receiving a pre-set first waveform data package, wherein the pre-set first waveform data package comprises first waveform data composed of digital signals; verifying the received first waveform data package, and determining whether the first waveform data in the first waveform data package meets a pre-set criterion; and if the first waveform data in the first waveform data package meets the pre-set criterion, storing the first waveform data, and outputting a laser pulse according to the first waveform data. The method reduces errors in a data transmission process, and facilitates the improvement of the accuracy of a laser pulse output finally. In addition, an application scenario of the laser is simplified, and the intelligent performance of laser application is improved. The present invention also relates to a quasi continuous wave laser and a laser cutting and welding system.

Description

【Technical field】 [0001] The invention relates to the technical field of lasers, in particular to a working method of a laser, a quasi-continuous laser, and a laser cutting and welding system. 【Background technique】 [0002] Quasi continuous wave (QCW) lasers, also known as long-pulse fiber lasers, are a type of fiber lasers that can generate pulses on the order of ms, with a duty cycle of less than 50%, and the average power is the maximum peak value. It is less than 10% of the power, and has excellent pulse power and energy stability, making it widely used in laser welding, laser cutting and other fields. [0003] In laser welding, the laser is usually used in conjunction with the board. The board is used to control the position and movement of the laser and provide the laser with an analog quantity, so that the laser outputs the same shape of laser pulse according to the analog quantity. [0004] In the process of realizing the present invention, the inventor found that ...
