Prior to welding, all tubes of the fuselage are drilled to allow passage of anti-corrosin fluid within the welded
structure. Having all of the tubes interconnected in such a way permits the entire structure to be pressurized. This is a very efficient method of checking that all of the welds are 100%
complete. All components are TIG welded and locally stress relieved. After which, all parts are thoroughly sandblasted, and powder coated. The color most often chosen is a off-white or
almond. Almost any color is available, usually at no additional charge.
