Similarly, the eye injury hazard distance (NOHD) does not mean that a laser is likely or even capable of causing injury over the entire distance. Remember that there is a built-in safety factor of about 2/3. If a pilot is hit by a laser at 1/3 of the NOHD, there is a 50% ch...

Laser cutting technology is a very useful development that has occurred over the past half-century. Also, laser cut steel is an important application of laser cutting technology. Because various steel materials are widely used in life. A high-density laser beam irradiates onto the steel surface ...
2 Lasers The term LASER is an acronym for Light Amplification by Stimulated Emission of Radiation and is the realisation of a concept postulated by Einstein in 1917 in the course of a theoretical investigation of blackbody radiation. However the problems of developing a satisfactory quantum theory ...

Of course, it's also a great rod for beginners, too. Set the welder between 50 and 65 amps. I've found that this is where this welder will run 3/32 in 6011 well. Put the desired rod the the electrode holder, or stinger, and you're ready to strike an arc! To strike the arc,...
light curtains provide perimeter guarding whereas laser scanners provide protection for larger portals into areas such as conveyor and robotic cells. As with all safety components, use of laser scanners requires calculation of the minimum safety distance. This value depends on the overall system stoppin...
There also are, of course, seasonal radiation variations caused by the tilt of the earth with respect to the sun. Thus, the winter sun will daily provide less than 20% of the summer sun's energy at some locations because it is lower in the sky and the days are shorter. *A micro...
