Helpful Guide To Laser Engraving

The laser engraving industry is relatively new. When lasers appeared on the market it didn't take long for the engraving industry to discover that lasers could be used for a wide variety of industrial applications including welding, heat-treating, etching and engraving. Think of a laser as a light source similar to a light bulb; a light bulb will emit energy out all around it rather than focused. Almost all materials can be laser engraved or laser marked.

There are a many advantages to using a laser over other methods of engraving; first of all, because the tool is a beam of light, there is no product contact, which translates into less chance of product damage or deformation. Unlike the conventional engravers some engravers use an intense beam of light instead of a rotating or vibrating tool; this beam can either vaporize a small area of the surface (laser engraving) or cause a change in the color of the surface of the material (laser marking) this beam is controlled by a computer at very high speeds and accuracy to give outstanding quality at a very cost-effective price.

With advanced software you can laser engrave just about anything from Bar Codes and 2D codes to photographs and company logos. Some people call it laser etching; others call it laser engraving but basically the technique uses a computer-controlled laser beam to mark a surface.

Laser etching can be used on many materials including slate, granite, stainless steel, leather, arborite, glass, mirrors, and premium hard woods. It's the process of marking the material without cutting all the way through using reduced power.

A laser works well for cutting acrylic (Plexiglas), PETG, thin polycarbonates (Mylar), styrene expanded PVC (Sintra), wood, paper and fabric. And laser cutting adds high precision, reduced contamination or warping, and a quality finish to industrial cutting applications. It offers a superior cut-edge quality with parallel sides and no burrs.

Laser marking services can be used for many thousands of applications from computer keyboards to special promotional gifts. Because no inks are used the marking services are both permanent and the process is kind to the environment. The marking is flexible, programmable and environmentally clean.

And laser marking of glass by Co2 lasers on the fly or while moving can be an excellent addition for many industrial environments and applications for glass marking. Co2 lasers can provide excellent results for marking glass and also provide significant reductions in operating costs and cost of supplies. You can laser mark most plastics from cattle tags to backlit day/night key switches.

Products that can use this process to engrave include wedding giveaways, nametags, table nameplates, trophies, woods, etc. And engraving metal uses the most power especially if the metal is of the harder type.

There are no consumables so operating costs are minimal, and the laser machine and system, if properly exhausted, runs clean, so that costly cleanup or by-product disposal is unnecessary. Also the laser engraving services are available today in most specialty stores because it's now the most common type of engraving. Of the many items being laser engraved today, iPods and laptops rank among the most popular in the consumer marketplace.

Laser Machine Welding

Laser machine welding is the joining of two pieces of material, usually metal, but often these days plastics, using a laser beam. A laser is a single phase, or coherent beam of light often seen in science fiction movies, but the development of the laser beam and its application in laser machine welding allows for advancements in precision welding using this high-energy device, which creates heat when it strikes a surface. Laser machine welding is used for steam tracing and inspection, for surface heat treating, cutting with heat and other precision applications.

The laser, which stands for light amphlication by stimulated emission of radiation, emits photons in a narrow beam. Laser light usually in monochromatic, meaning that it emits light of a single wavelength. Common light emits incoherent light, which goes in all directions over the spectrum. The first working laser was developed by Hughes labs in 1960, but was descended from work done by Albert Einstein in 1916. However, the laser itself is such a recent development that the use of laser machine welding is a fairly recent technological innovation.

Lasers have found applications in many areas since their invention. Modern medicine utilizes lasers for surgery, having realized the ability to perform less invasive surgical procedures than in the past. Also the fine and precise nature of lasers has led surgeons to use them for such delicate operations as eye surgery. In common practice many people today use laser pointers, especially in the classroom. Marksmen use laser sights on rifles. Computer users use laser printers for output rather than old-fashioned methods, and lasers are used for motion detection and security, among many dozens if not hundreds of other applications. Lasers are even used in children?s toys, office photocopiers and in the devices used to lock and unlock car doors. As technology improved lasers worked their way into all aspects of life and it was only natural that applications of lasers to welding technology would occur. The end result of this has been the creation of the laser machine-welding specialty, taking its place next to Mig, Tig, Arc and other welding methods.

Uses of laser machine welding are becoming commonplace in the computer and consumer electronics industry, in space and aircraft technology and with defense contractors. Laser machine welding is often used because it can be much more precise than other welding methods. Laser machine welding is often used for micro welds of hyper small dimensions that conventional welding methods could never touch. Laser machine welding is often used in jewelry manufacturing, engraving, in dentistry, and in the tool and die industry where precision is demanded. Laser machine welding is on the cutting edge of technology, and welders trained to use laser machine welding are some of the brightest and most talented welders in the industry.

Laser machine welding has also found a home in the highly technical and precise welding needs of plastic welding. While plastic welding is often done with ultrasonic welders, many times laser machine welding is the preferred method.Peter Vermeeren is the owner and webmaster of: http://www.machine-and-tool.com - http://www.kamikaze-portal.com and http://www.airsoft-got.es
