The working of laser welding: An important welding type
Comprehending the process of laser welding can be intense and at times confusing, especially if there is a recent acclimation to this important application of welding. Laser welding is increasingly becoming an important welding type and differs in a number of ways from typical welding. Effective use of laser welding technology requires the right know-how for production/manufacturing processes to righteously fall in place. In the past years, the most efficient lasers were only 10 percent as effective as today’s, with incredibly lower running costs. Laser welding is more like a tool in the tool-box. It is being used for a number of applications, be it the automotive, consumer, med-tech, or biomedical industry and much more. There are a ton of applications that have not utilised laser welding yet.
The process of laser welding and 3-D printing
In laser welding, two materials are joined together. For this purpose, the two sides of the material being abutted are melted. This melt further coalesces and forms a joint. Laser beam welding has been in usage since the past three decades, but it is only in the recent years that its usage has increased for a number of industrial applications. In fact, until recently, it has been used selectively and has been in a fierce competition with the traditional methods of welding. It is due to the modern-day additive methods of production such as 3-D printing of metals, laser welding is consistently gaining more importance. Laser beam welding is a highly automated process and can in no way be compared to the conventional, manually guided methods of welding. It can be therefore said that the joining process as part of laser welding is a highly safe production step. During the process of laser beam welding, the work piece is strongly clamped in a fixture.
Laser beam welding
The modern-day laser beam welding systems are well-equipped with a highly integrated measuring system that works independently to accurately check the dimensions of the component being manufactured. This makes laser-welding systems highly accurate, forming the basis for guaranteeing the best quality.
The advantages of laser welding can be as follows;
- High accuracy
- Torsion freedom
- High speed of joining
- Consistency in quality
- Wider material tolerance
Conclusion
In the past one decade, manufacturing has embraced laser welding more than ever, yielding results that have been highly efficient. The modern-day lasers are easy to maintain, modular, highly accurate and highly efficient.
