Metal-Stitching as a Stronger Alternative to Welding

Recently Pumpcoat had a repair and coating project for a series of wicket gates from a hydro unit. Some of the gates had cracks in the metal. Rather than employ the traditional welding for repair, Pumpcoat contracted repair specialists who used a technique called Metal-Stitching. As Cast metals are very difficult to weld, the Metal-Stitching technique is a great alternative. This procedure involves using stitching pins to fill in and seal the cracks and metal locks to splint the crack horizontally. The end result is a much stronger repair than welding. The repaired gates were then coated and put back into service. The Metal-Stitching process is seamless and can be used on a variety of cast metals. Repairs can be done on many different metal parts or pieces of equipment.
