Renewed Why Laser Welding?

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
