Modern CO2 machines usually produce the laser beam in a sealed glass tube which is filled with gas, usually carbon dioxide. A high voltage flows through the tube and reacts with the gas particles, increasing their energy, in turn producing light. A product of such strong light is heat, heat so strong it can vapourise materials that have melting points of hundreds of °C.

Here the joining takes place in solid state and no phase change occurs. However, in solid state welding, parent components may be heated to an elevated temperature but substantially below the melting point of the concerned material (and thus no melting occurs). Instead of external heat, application of pressure is usually necessary for this type of welding. Roll welding, diffusion welding, friction welding, etc. are considered as solid state welding processes. Following passages elaborate similarities and differences between fusion welding and solid state welding.

Weld mesh is constructed from durable steel wire which is electronically welded at each contact point resulting in a terrifically strong and versatile material. Our steel weld mesh is electronically welded at each intersection making it suitable for a huge range of demanding applications. It is virtually unbreakable and very easy to fabricate, and as a result, it is used to create a variety of safety guards and screens.

The coils on the HVAC equipment in your home — such as an air conditioner or air purifier — are prone to the buildup of harmful bacteria and mold. When these coils aren’t cleaned properly, airborne contaminants circulate into your home. This makes it uncomfortable for family members with respiratory problems, and it can aggravate allergies or asthma and also cause sickness. Using a UV lamp to sterilize the coils on your HVAC equipment has been proven to improve indoor air quality.http://www.uvwavetek.com/222-n....m-far-uvc-light/far-

Sustainable fashion materials are very durable and built to last, making them easy to care for! There should be no issue using a machine to wash your sustainable items, but always be sure to check the tags to be on the safe side. Unless the tags say otherwise, opt for a mild detergent when cleaning your clothes. And, if you want to give your garments a special treatment, try Ultimate Care Fresh Skies.
