Siemens VAI MT,France ASOLID laser Welder

摘要

For many years,the mash lap technology for welding light gauge strip has been the only alternative to steel suppliers.But the search for better weld profiles with no over thickness as well as increased component lifetime,and the move towards higher strength steels has led to other technologies such as laser.In 2000,Siemens VAI launched an extensive Research and Development program to develop laser welders capable of the best performances.Light laser welder (for galvanizing,annealing,and finishing lines) and heavy laser welder (for pickling line and tandem mill) were the results of this R&D program with a first machine installed in 2004 using a CO2 laser source.Through continued research efforts and always willing to be ahead in terms of technology,Siemens VAI has now reached a new step with the integration of an ASOLID laser source to its light laser welder.This laser source replaces the CO2 resonator.This new technological step gives a lot of benefits to steel producers with a higher efficiency,lower consumptions,higher process speed for cutting and welding,easier maintenance with no mirror installed on the machine… and many other advantages.
