How to Weld ELASTIMOLD Apparatus Bushings and Bushing Wells
This guide provides suggested recommendations for welding ELASTIMOLD apparatus bushings and bushing wells, focusing on minimizing heat to maintain epoxy integrity. It covers welding processes, materials, heat sink usage, and recommended procedures.
Estimated time: 1h 30m
Tools needed:
Inert-gas, tungsten-arc welding (TIG) equipment, Short-arc welding (metal inert-gas, MIG) equipment, Thermocouple detectors
Supplies needed:
No. 308 bare stainless steel wire, Copper heat sinks, Thermally conductive paste
- Prepare Apparatus and Work Area
De-energize all apparatus. Inspect parts for damage, rating, and compatibility. Verify package contents are complete and undamaged. Clean all surfaces (tank, bushing, and bushing well) to remove contaminants. Ensure a clearance of 3/16” ± 1/16” between the epoxy shank and mounting hole, and that the enclosure cover thickness is a maximum of 1/4”. Have all required tools and supplies ready.
- Install Heat Sinks
Position copper heat sinks to minimize heat flow to the epoxy. Apply thermally conductive paste to the faces of the heat sinks in contact with the flange and cover. Ensure the bottom heat sink has a larger diameter than the top. Provide adequate venting for the heat sinks. Do not thread heat sinks to the bushing or bushing well stud. If using non-water cooled sinks, remove them promptly after welding and air cool the bushing.
- Perform Welding
Use either Inert-gas, tungsten-arc (TIG) or Short-arc (MIG) welding processes with No. 308 bare stainless steel wire. Keep heat to a minimum; the visible heat line must not exceed 1/8” from the weld or 3/16” from the O.D. of the flange. Minimize air currents in the welding area. Monitor temperatures with thermocouple detectors to ensure they do not exceed 225°F at critical points. Avoid applying torque to the epoxy during bus bar connections and minimize forces on the heated stud and flange during handling.
- Post-Welding and Environmental Considerations
Ensure the oil level covering the immersed stud connection is greater than 2 inches. If thermal baking is required for equipment surface finishes, the bake sequence must not exceed 130°F or 8 hours. During this cure process, do not mechanically load the bushing metallic contacts internally or externally to prevent epoxy distortion. Note that ELASTIMOLD bushings are not designed for use in air, except for the 600T1 with boots and collars.
