Welding Nozzle protects weld zone and laser beam delivery optics.

Press Release Summary:

Enhancing laser welding abilities of 3- to 7-axis 795, 430 BD, and 430 Vera laser processing systems, SmartShield™ lens and nozzle assemblies protect against excessive oxidation in weld area. High-velocity gas barrier prevents metal sparks from weld zone contaminating protective lens cover slide, and cross-jet does not contaminate or otherwise interfere with welding shield gas. Focusing lens/shield gas assemblies can be changed to vary focused spot size or from welding to cutting or drilling.

New LASERDYNE SmartShield(TM) Welding Nozzle Simultaneously Protects Weld Zone and Laser Beam Delivery Optics -- Enhances Laser Welding Capabilities of the LASERDYNE 795, 430BD and 430 Versa Systems

Champlin, Minnesota: 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 aluminum alloys, copper alloys, titanium alloys, nickel based super alloys and stainless steels including Types 304 and 316.

SmartShield is the newest   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.

The shielding gas shoe provides a controlled atmosphere for the weld zone when molten and while it is cooling to a temperature at which it will no longer be compromised by the ambient atmosphere. This is important for welding materials, such as titanium alloys, that have a strong affinity for oxygen and nitrogen in the ambient atmosphere. 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.

“Our goal at Prima Power Laserdyne is to continue to produce advancements like SmartShield that expand the use of laser processing and make our customers more successful,” stated Terry L. VanderWert, president of Prima Power Laserdyne. “We are pleased by the acceptance of these new laser innovations and how LASERDYNE products are enabling precision laser cutting, welding, and drilling by system users around the world.”
