The Benefits of Laser Welding 
(1) Strength of the Joint
A Laser Welded section possesses a "Clean Joint" which retains the inherent strength of the parent metal.
(2) Minimal Profile Distortion
Unlike standard Hi-Frequency welds, Laser welded sections possess a miminised HAZ (Heat Affected Zone)
(3) No internal weld bead
Profiles can be produced with consistent positioning of the weld seam which does not need to be dressed therefore offering greater scope for telescopic applications.
(4) Key Hole welding
The point of heat is highly restricted thereby creating a miminised HAZ (Heat Affected Zone)
