High strength steel is a kind of steel often used in engineering construction. With the improvement of technical level, the research and development of high strength steel in China has made remarkable achievements. The application of high strength steel S690QL1 material in the construction field can reduce the steel consumption and building volume, and improve the building weight. That is one of the important reason why the high strength steel is so warmly welcomed nowadays.

Laser cutting, it is a specific way of cutting S690QL1 material steel plate cutting processing, is also one of the common way of cutting its on the cutting or machining parameters, if you want to get the right number, is that you can adjust these parameters to achieve a goal, adjust a few times more to get accurate numerical right in addition, we also need to know is, the faster the cutting S690QL1 material speed, the light intensity is smaller, so, the smaller the laser penetration is, in turn, can control the penetration depth of laser.
