Manufacturing process nowadays is very safe and efficient thanks to the advancements being brought every day to the metal fabrication industry. This technological advancement has brought back the desired industrialization that people hoped to see after the Industrial Revolution. Laser cutting, metal bending, metal rolling and almost every stainless steel fabrication, aluminium fabrication, and steel fabrication process have brought new dimensions to the metal fabrication industry over the years. These inventions and advancements have made the industries profitable and the one which made the best out of it is the laser.
Laser technology made an impact so big that none of the others were even close. Its impact can be felt throughout the entire manufacturing industry, not only for its cutting ability but also for its welding feats too. New and proficient generation forms are frequently impractical without the upsides of laser innovation. Along these lines, assorted sheet thicknesses and characteristics are transformed into custom-made spaces by welding and protection spot welding is supplanted by laser seams.
Laser welding has almost become paradoxical in how efficient and flexible it is compared to the weld joint geometries. When the fabricators can consider how restrictive and bound the requirements are for the highest possible gap, they’ll easily know why. Although it is true that maintaining a minimal gap seam in important for broad range of ways for assembling a part for laser welding, it is immensely beneficial to consider its effects on the upstream processes.
Today’s modern laser is capable of cutting metal parts more consistently, quickly, and with clean edges. With the laser welding, fabricators can achieve higher speed for welding that results in a weld seam. The part is finished when the weld work is finished.
How does it work?
Laser welding can be done by hand but most of the systems are automated these days. These systems use Computer Aided Manufacturing (CAM) which is based on the Computer Aided Designs.
The laser beam welding is for the most part utilized for joining segments that should be attached with high welding speeds, thin and little welding seam & low thermal distortion. The higher welding speeds, a phenomenal programmed task and the likelihood to control the quality online amid the procedure to make this laser welding a typical joining technique in the cutting edge modern creation.
There are different types of laser available for commercial use, but mostly two of them are used for laser welding. They are Solid State Laser and the Gas Lasers.
Solid State Laser operates at specific wavelengths on the order of one micrometer, which is much shorter compared to the gas lasers for weld works. The gas laser uses high voltage and low current power source to supply just the amount of energy needed to excite that gas mixture that is used as a lasing medium.
Laser Welding Machine Type
Modern-day laser beam weld machines can be grouped into 2 major types. The traditional type and the remote type. In the traditional types, the laser output is moved to precisely follow the seam and it is mostly done by a robot.
In Remote laser beam welding, the laser output is moved precisely with the help of the laser scanner. This laser welding machine has many advantages over the traditional ones. But the higher precision and speedy finish are the most noticeable ones.
