Weld Repair and Overlay

J~S Machine & Valve Inc. performs thousands of stellite weld repairs/overlays every year. Our stellite welding processes include TIG (Tungsten Inert Gas), MIG and STICK (Shielded Metal Arc Welding).



Custom Projects

Before and after pictures of a “wedge” out of a “24 inch 2500 pressure class main steam block valve.

In addition to overlays we are often called upon to rebuild base metal in valves or equipment to restore critical dimensions and fits including weld build up of damaged or pitted stems.




Breakdown

Before and after pictures of a “wedge” out of a “24 inch 2500 pressure class main steam block valve.

This is the full repair we engineered an attachment to one of our machines that allowed us to “single point machine” threads in the stud holes that we repaired.

    Repair steps:
  1. Bore out existing threads and corroded base metal
  2. Weld the holes back up
  3. Bore back out to correct size for threads
  4. Single point thread to original OEM size/specifications
