Laser welding is a rapidly developing and versatile technology which has found increasing applications in the manufacturing industry. With this state-of-the-art joining technique, we can repair / finish a tool and inserts; quick and better. It is also far more effective and efficient than conventional welding technologies. It allows the precision welding of small and hard-to-reach areas. For machine shop technicians, this technology is a gateway to the endless possibilities and for the Die Tool Room it opens up many new vistas.
A quick comparison between Laser and TIG Welding
| TIG | Laser | |
| Wire pool size | 2-10 mm | 0.1 to 0.4 mm |
| Heat Input | Very High | Extremely Low HAZ |
| Penetration | Max 5 mm | 0.1 -10 mm |
| Filler Wire | Hand held or upto 5m/min | Autogenous or Hand Fed |
| Dilution of Dissimilar Metals | Cracks seen sometimes | No Cracks |
| Distortion | High | Negligible |
| Energy Efficency | More Enegy Required | Low |
| Precision | Low | High |
| Performance | Average | Excellent |
| Weld pool Area | Very Big | Very Small |
