I have a YAG laser spot welder. I want to put an infrared quartz glass on the surface of the welding alloy to prevent sparks from splashing.I did a test to put a circular flat lens in the laser spot welding machine (infrared quartz glass bar) on the top surface of welding, and always put a shallow impression on the side of the lens,Is there any kind of glass that I want, that can pass through the laser and not leave a mark on the glass so that the glass can be reused?.
First, does the print affect your use or work?Each laser head has a lens, you look for welding machine manufacturers to buy a glass like this
The nearer the focus is, the higher the temperature is, the only way away from the focus!Solution: the design of a high cover, only the top is transparent glass can not have
The output wavelength of YAG laser is 1064nm, so you need to choose 1064 high transparent film coated glass, also should pay attention to anti damage threshold of this glass, because the laser power you use should be relatively high, therefore, the glass you use the anti damage threshold should be a minimum of more than 1000MW/cm2.
