Welding Nozzle Smartshield
Welding Nozzle Smartshield
Laserdyne’s new SmartShield™ Welding Nozzle provides protection against excessive oxidation in the weld area, enhancing laser welding capabilities of the 3 to 7 axes 795, 430 BD, and 430 Vera laser processing systems. Previously published welding data show that positive results are achieved with effective protection from oxygen in atmosphere during laser welding of a range of materials, which are highly sensitive to oxidation. These include aluminium alloys, copper alloys, titanium alloys, nickel based super alloys and stainless steels including Types 304 and 316. SmartShield is the newest addition to the line of proprietary Laserdyne lens and nozzle assemblies. Patent pending SmartShield provides a high velocity gas barrier that prevents metal sparks from the weld zone contaminating the protective lens cover slide. Critical to the SmartShield design is that the cross-jet does not contaminate or otherwise interfere with the welding shield gas. The SmartShield nozzle is designed so that it can be used with an entire range of shield gas delivery devices including welding shoe and coaxial gas nozzle tips. An important benefit of this design of the focusing lens/shield gas assemblies for laser welding is that they can be quickly changed to vary the focused spot size or to change from welding to cutting or drilling. SmartShield is one of many new features from Laserdyne to support development of new laser welding applications both with and without filler metal addition.
