Welding Safety Glasses
Visible Light Transmission for each lens shade: Shade 2 = 20-28%, Shade 3 = 10-14%, Shade 5 = 2-4%
Welding goggles provide a degree of eye protection while some forms of welding and cutting are being done. They are intended to protect the eyes not only from the heat and optical radiation produced by the welding, such as the intense ultraviolet light produced by an electric arc, but also from sparks or debris.[1] A full facemask may be required for arc welding.

Welding Safety Glasses help protect welders against Photokeratitis, also known as "welder's flash." Welding Safety Glasses are designed with Shade 3 or Shade 5 Lenses and are primarily used for torch soldering, brazing and cutting. Welding Safety Glasses are not intended for arc welding, which requires a darker lens found in Welding Helmets (OSHA's 29 CFR 1910.252 lists the minimum lens shade requirements for a variety of welding operations).
Welding and cutting processes, including arc welding and cutting, as well as brazing produce intense ultraviolet (UV), infrared (IR) and visible light wavelengths. The UV and IR wavelengths cannot be seen and can produce eye injury without the victim realizing it immediately. Extremely dark filters of the proper sort are needed for the welder to be able to look at the intensely glowing metal being welded. An approved face shield or welding helmet can also have filters for optical radiation protection, and offer additional protection against debris and sparks.[2] UV blocking protective spectacles with side shields or welding goggles are considered primary protection, with the face shield or welding helmet considered secondary protection.[3] This way, the eyes are still protected even when the face shield or helmet is lifted up.[4]
The optical filter in welding goggles, face mask or helmet must be a type which is suitable for the sort of work being done.[5] A filter suitable for gas welding, for instance, should not be used for arc welding. Face masks which are self dimming are available for arc welding, MIG, TIG, and plasma cutting, and allow better vision before the arc is struck and after it is extinguished.[6] Failure to use such protection when arc welding or even being near where arc welding is going on can result in a painful condition called [arc eye" or photokeratitis, which is akin to a severe sunburn of the cornea and conjunctiva of the eye.
L'Orange introduces a new high performance and efficient turbocharger
Recently, Germany's leading injection technology manufacturer L'Orange has introduced a new high-performance and high-efficiency turbocharger for large engines in the marine, offshore, power generation and railway sectors, including not only diesel but also gas engines. And dual fuel machines.
According to Olav Altmann, head of sales at L'Orange, the engine needs high performance, low consumption, low pollution emissions and a well-coordinated operating environment, even for short moments. Individual components cannot be fully implemented and require a coordinated system. With the new turbocharger products, we can meet different customer needs without compromising performance and efficiency. The new turbocharger is perfectly matched to other L'Orange components and is well integrated into the overall engine package.
Large diesel engine users are always looking for engine reliability, efficiency, safety and performance. The latest L'Orange turbocharger is available to provide customers with solutions to meet the upgrade needs of large diesel engines on the market.
It is reported that the newly launched ZR series turbocharger is jointly developed by L'Orange and MTU Friedrichshafen, which can save time and cost for engine R&D and operation. According to customer needs, L'Orange can provide 500-10000 for engine. Kilowatt ZR turbocharger.
L'Orange is the world's leading manufacturer of injection technology and a subsidiary of Rolls-Royce Power Systems. It has manufacturing facilities in Germany, the United States and China and employs more than 1,000 people.
