Welding involves joining metals by heating them until they melt. The practice dates to the Bronze Age when humans melted copper alloys and pounded them together on flat surfaces such as anvils using hammers. Today, welded items are everywhere, from the cars you drive to the planes you fly and the skyscrapers in which you work. Welding techniques are constantly evolving and incorporate the use of powerful lasers, robots and computers. Laser Technology"Laser" is an acronym for "light amplification by stimulated emission of radiation." They represent high energy beams generated at one or more discrete frequencies. Two types of lasers can be employed for welding. The first kind involves hard optics, or the use of mirrors and lenses to focus and deflect the laser beam. The second kind involves fiber optic cables to channel the laser beam with little loss of energy. One of the main advantages of fiber optic lasers is that they allow for the repositioning of the laser beam, whereas hard-optic lasers require the object being worked on to be moved. Welding With LasersLike other welding techniques, lasers are designed to heat a surface to join it with another. Laser welders accomplish this by delivering a pulse of light focused on a small area measured in millimeters, if not tenths of millimeters, in diameter. As the surface absorbs the laser's light, it vaporizes the metal, creating a gap known as a "keyhole." When the pulse ends, the liquefied metal surrounding the keyhole flows inside, resulting in a weld between the two surfaces. Advantages of Laser WeldingLaser welding offers certain advantages over traditional welding techniques. Because lasers generate a minimal amount of heat and can be precisely focused on any surface, the resulting welds are relatively small. This makes laser welding particularly suitable for thin products such as electronics or glass-to-metal seals. Another key advantage of laser welding is its fast welding rate in applications such as gas metal arcs and submerged arcs. Also, laser welding allows for better access to welding locations and doesn't generate any debris during resistance welding processes.
