SUMMER INTERNSHIP REPORT FINITE ELEMENT TRANSIENT THERMAL ANALYSIS OF LASER WELDING PROCESS ABSTRACT In this project‚ Laser welding process has successfully been used for joining of two stainless steel plates. The sizes of the metal plates are 50mmX40mmX2mm each. The distribution of the temperature field in laser welding using stainless steel sheets were simulated by ANSYS. The thermal properties which have been used for thermal simulation are assumed to be varying with temperature

Lasers are originated as an acronym for "light amplification by stimulated emission of radiation". A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. Numerous logical‚ military‚ restorative and business laser applications have been produced since the creation of the laser in 1958. One of the most common uses of lasers is laser hair removal. The concept of laser hair removal was invented by Dr. Rox Anderson

LED and Laser Transmitters LED Transmitter Light - emitting diode (LED) is a standard light source that carries low speed signals at short distances. LED light source is an all plastic fiber that transmits visible light. LED put out lower power and a bigger output pattern than laser light sources. LEDs have less bandwidth and are limiting to operate up to about 250Mhz or about 200Mbs. LED light sources do not contain hazardous material and last longer‚ about 10‚000 hours. Bulbs generate less heat

While both laser therapy and scaling and root planing are both effective treatment methods for periodontal disease‚ scaling and root planing is used as a traditional method also called a deep cleaning while laser therapy is used as a relatively new alternative therapy. Both methods are usually used for patients who have periodontal disease with gingival pocket depths over 4mm. Though scaling and root planing has been the conventional treatment in the past‚ since 2008 laser therapy has doubled in

Laser hair removal was performed experimentally for about 20 years before it became commercially available in the mid-1990s.One of the first published articles describing laser hair removal was authored by the group at Massachusetts General Hospital in 1998. The efficacy of laser hair removal is now generally accepted in the dermatology community‚[citation needed] and laser hair removal is widely practiced in clinics‚ and even in homes using devices designed and priced for consumer self-treatment

Laser projection keyboard is one of gadget that developed for a long time but it wasn’t popular. Seems like most of people really like this gadget.However a few years later laser projection keyboard was created for using with IPad and IPhone. When a user touches the surface cover by an image of a key ‚ the device records the corresponding keystroke. A laser projection keyboard was invented and patented by IBM engineer in 1992. It optically detects and analyses human hand and finger motions

Types and benefits of Laser Skin Resurfacing Laser resurfacing is a procedure of skin resurfacing that makes the use of laser for treating minor flaws on your face or to enhance the skin appearance. It is usually done with two kinds of laser. One is ablative or wounding laser that eliminates thin skin layers and the other being a non-ablative or non-wounding laser that boosts the growth of collagen and tightens up the underlying skin. Non-ablative laser resurfacing being less invasive requires little
