Claims5
A method of manufacture and installation for a spring hanger replacement pad comprising
- hot forming a spring hanger replacement pad of approximately Rockwell C hardness 30 to the original size and shape of the spring hanger pad surface which is to be replaced,
- welding said pad to the spring hanger mount, and
- cooling the weld slowly by use of a high temperature blanket to insulate the weld area from its environment.
The method of manufacture and installation for a spring hanger replacement pad comprising
- hot forming a 5160 spring steel replacement pad to the original size and shape of the spring hanger pad surface which is to be replaced,
- air cooling said pad to a Rockwell C hardness of approximately 30,
- shot peening said hanger pad before welding it to the hanger surface welding said pad to the spring hanger over the original pad surface with as short a welding arc as possible using a number of narrow beads and no weave beads with only a sufficient current to obtain a smooth arc and proper fusion of weld metal to base metal and using the welding rod manufacturer's welding rod size to amperage settings on the welder, and
- cooling said weld slowly by use of a high temperature blanket to insulate the weld area from its environment.
