Advantages of Laser Welding

Laser welding

The advantages of over TIG and MIG are numerous. These processes can penetrate the material deeply, and they can weld very thick joints, which would otherwise require multiple passes with a TIG or MIG welder. This would result in a 15 to 50-times faster process than TIG or MIG welding. And these advantages can be further compounded when you consider the time savings that provides over MIG or TIG.

The three most common types of lasers are gas, solid-state, and fiber. These lasers produce the weld beam by delivering light to the workpiece through optical fibers. Single fiber laser machines use a single fiber to deliver the beam, while multi-fiber machines use several fibers connected to the workpiece. The strength of the laser beam increases with each fiber connected to the workpiece. Some fibers also have a collimator lens, which helps focus the beam.

When considering the advantages of laser welding, it is crucial to understand how lasers work. A typical example of a fusion welding process is that of aerospace aircraft. A laser can be used to weld aluminum-based Dural. This is easier to work with than steel because it is much lower in temperature. In fact, aluminum-based Dural is far more efficient to process than steel, which needs two-and-a-half times as much energy to melt. That is why laser welding systems are so efficient in steel construction.

Laser welding is a relatively new method of joining two pieces of material. This technology requires access to the weld zone from either side. The intense beam of laser light that is generated by the weld will heat the material on both sides of the joint and then resolidify. Afterwards, the parts will be joined. With the use of lasers, welds are able to join complex objects. For this reason, this process has gained popularity.

In addition to being able to weld parts with a tight tolerance, low heat input laser welding allows for the joining of conventionally prepared and unmachined parts. It has the added benefit of broadening the weld window by five times. A common problem with welding parts that are too large for a typical welder is how to weld them properly. With low heat input laser welding, the parts are able to be fastened despite their size.

Although the cost of laser welding can be expensive, the benefits of laser welding far outweigh the costs. Lasers are generally a more expensive option than arc welding, so a high-power, efficient laser can save a substantial amount of money in the long run. If you are in the market for a machine to weld thick metal, it is advisable to look for a high-performance industrial laser welding system. Once you have the right machine, you will have no trouble creating beautiful welds that are free of flaws.

Besides being more efficient, laser welding can be used to fabricate fluidic channels. The first application of this technology was to weld two transparent polypropylene sheets onto one black polypropylene sheet. Using a laser with selective transmission allows partial overlap between successive scan lines, resulting in a stronger weld. A second pass can be performed using orthogonal scanning directions. This type of laser welding has been used by the military, aerospace, and automotive industries.
