Laser light energy is measured using wavelengths, or nanometers (nm). Specific wavelengths are used for different applications and can only be generated by certain types of lasers.
Fiber lasers stimulate a rare-earth metal known as ytterbium to generate photons on the 1,064 nm wavelength. This wavelength is ideal to mark metals, as a good quantity of its energy is absorbed by the material.
CO2 lasers stimulate CO2 gas to generate wavelengths between 9,000 nm and 11,000 nm, covering a wide range of organic materials that require different wavelengths. The most common wavelength for organic materials is 10,600 nm.http://www.whamark.com/laser-marking-machine/

It is also worth mentioning that fusion of the faying surfaces of the parent components is not necessary for weld bead formation. In some welding processes, the faying surfaces are fused with the application of heat to get the weld bead, while in other processes, weld bead can be obtained without melting the faying surfaces. On the basis of whether base materials are fused or not, welding processes can be broadly classified into two groups—solid state welding and fusion welding.

Since the germicidal properties of sunlight were discovered over 100 years ago, ultraviolet (UV) light technology has been adapted for cleaning and sanitizing. Take advantage of UV light’s germ-killing properties in your Harleysville, Pennsylvania, home by installing a UV lamp on your air conditioner or air purifier. Here’s how a UV lamp protects your home from invisible, airborne invaders.

That’s why, when it comes to clothing and fabric, we believe in quality over quantity. And what better way to prioritise quality – and the environment – than by choosing sustainable textiles and eco-friendly fabric?
Sustainable fabrics offer loads of benefits for the planet, your wardrobe, and even your bank account. We’re going to dive into questions like “what are sustainable fabrics?” and “is cotton biodegradable?” But first, let’s discuss what sustainable fabric really is.http://www.suzhouzhifan.com/sustainable-fabric/
