Structural welds must maintain a part’s dimensional characteristics without damaging material coatings or leaving deposits on electrodes of the weld equipment. It’s a problem that requires precise balance between the weld process and the inherent properties of light gauge coated sheet metal.
Wright-K Technology patented projection-welding process, HY-PAK®, solves this problem. Our welding process generates a high magnitude heat for a short duration. Teamed with our low inertia weld head, capable of carrying a 40,000 to 60,000 amp weld pulse, the mechanical follow-up characteristics set down the projection in less than five milliseconds.
