Arnold Voigt is Al’s brother and lives in Seattle, Washington.
My wife Roxy and I designed and created the Protector sculpture. We assembled the sculpture in my brother’s sculpture barn at the Voigt Family Ranch, with the help of Doug from time to time.
The materials of construction are a combination of Stainless Steel and Carbon Steel tubing both Square and Round configurations. The Protector sculpture was created using a combination of mechanical joining and fusion welding. The Stainless Steel Dome element for the Protector sculpture was originally fabricated as part of a Delta II second stage rocket fuel tank system designed for placing satellites into low earth orbit, but it was found to have small internal defects that made it unsuitable for flight hardware.
The Stainless Steel Dome element is a Martensitic Grade of 400 series Stainless Steel which contains Chromium as the primary alloying addition in an Iron base system with the Chromium providing corrosion resistance. The Dome element started out as a flat sheet of metal approximately one tenth of an inch thick that was then flame heated and hot spun formed to produce a large dome approximate 54” Dia. half sphere. The Flame Spun dome element was then polished to its thin final thickness on both the internal and external surfaces. The dome used in Protector was heat treated to produce a fully Annealed Condition.
The Carbon Steel tubing structural support elements were cold formed to produce a uniform radius of curvature on both large vertical supports. Cold forming was also used in forming the secondary internal and external side supporting elements. The Protector vertical tubular structure was flame and plasma cut to the final desired shape and fusion welded for assembly, followed by grinding and rough polishing. Exposure to the elements has provided the Iron oxide patina finish on the Carbon Steel.
