One of the most advantageous developments in the history of welding is the development of laser welding technologies.
Laser technologies in welding are superior to traditional welding in many circumstances for the following eight reasons:
A wide variety of metals can be worked with through laser welding.
It's possible to use lasers to weld not only stainless and high-strength steel, but also aluminum, titanium, and various precious metals. This makes laser welding a highly versatile welding technology.
Direct contact between the laser head and the material being worked with is not necessary.
The fact that contact is not necessary between the material and the laser head means that it's easier to be precise and avoid warping the material during welding.
The strength of the weld is strong even when the weld is very narrow.
With traditional welding, a narrow weld is sometimes so weak that it becomes problematic.
With laser welding, strength can be maintained even as the weld becomes more narrow because of the exceptionally advantageous depth-to-width ratio of a higher strength laser weld.
Lasers in welding allow for greater precision.
A laser beam is small and easy to precisely control. In comparison, a traditional welding gun is much more unwieldy and difficult to control during welding.
Laser welding is helpful when metal is worked on only one side because of limited accessibility.
Sometimes, access to a piece of metal that needs to be welded is limited. Traditionally, this would require the process of spot welding, which lacks precision and is very cumbersome and time-consuming for the welder.
Laser welding is particularly helpful in these situations because of its precision and of the smaller size of welding equipment that works through laser technology.
The welded material has a smaller heat-affected zone.
The larger the heat affected zone when a piece of metal is being welded, the longer it takes to cool down the metal so that it is ready for the next steps in the manufacturing or construction process.
With laser welding, the heat-affected area is small and precisely defined. This allows for rapid cooling and a faster manufacturing process overall.
Less scrap metal is produced when laser technology is used.
Any scrap metal produced during a welding operation detracts from the overall efficiency of the production efforts. The precision of laser welding leads to a minimal amount of scrap metal and a more efficient process.
Parts that are welded with a laser beam are much less prone to deformations and shrinkage.
Traditional welding makes deformity and shrinkage more likely because it requires that a larger area of the material being worked is exposed to extreme heat. Laser precision minimizes the area that's being worked and therefore also minimizes deformities. Click here to learn more about welding machines.
