Plating
Electroplating is an economical process and is used with
great success on small fasteners. However, its application to wireforms
and welded fabrications, while economical, requires that the industry's
plating standards, specifications and requirements be modified to balance
basic corrosion protection needs with a practical approach to the value
of wireforms and welded fabrications. A failure to do so will consume
supplier-customer quality relations, waste resources, and decrease value. |

Other Specifications Affecting Both Class 1 and Class 2 Plating:
- Only plating on areas classified as "Major Surfaces" will
be inspected for plating thickness (see below).
- Thread classes will be viewed as 'after plate' unless otherwise specified
on the drawing.
- Bearing surface areas must be clearly marked as to maximum diameter
after plating and distance of protected area.
- Plating on threaded surfaces, internal and external, will be considered
"reference" only.
- Plated and welded fabrications: black spots and bleed out will be
allowable within two inches of any welded area unless noted on the
drawing.
- Corners, surfaces, intersections, weld seams: any area that can
be touched by a 20mm ball should be visibly coated. For areas that
cannot be touched by a 20mm ball, plating coverage will be a "reference"
requirement.
- Tubes that have the ends closed should have a drain hole specified
on the blueprint to minimize the chance of seeping or bleed-out of
plating solutions after plating.
