How to Weld and Install ELASTIMOLD Apparatus Bushings and Bushing Wells
This guide outlines the recommended procedures and critical requirements for welding and installing ELASTIMOLD apparatus bushings and bushing wells, emphasizing heat management and proper clearances.
Estimated time: 1h
Tools needed:
TIG welding equipment, MIG welding equipment, Copper heat sinks, Thermally conductive paste, Thermocouple detectors, Cleaning supplies
Supplies needed:
No. 308 bare stainless steel wire, Appropriate HV insulated caps or connectors (if needed)
- Prepare Apparatus and Work Area
De-energize all apparatus before beginning work. Inspect all parts for damage, correct rating, and compatibility with mating components. Remove any protective shipping covers and replace them with appropriate HV insulated caps or connectors before submerging or energizing the circuit. Clean all surfaces of the tank, bushing, and bushing well thoroughly to remove paint, grease, or other contaminants that could extend welding time. Gather all required tools and maintain cleanliness throughout the procedure.
- Set Up Heat Sinks for Welding
Install copper heat sinks to minimize heat flow to the epoxy. Apply thermally conductive paste at the contact face of the heat sinks with the flange and cover. Ensure the bottom heat sink has a larger diameter than the top to absorb heat effectively. Provide adequate venting for the heat sinks. Do not thread heat sinks to the bushing or bushing well stud to prevent integrity issues due to expansion.
- Perform Welding with Controlled Heat
Utilize either Inert-gas, tungsten-arc welding (TIG) or Short-arc welding (MIG) processes with No. 308 bare stainless steel wire. Keep the heat to a minimum; ensure the visible heat line does not exceed 1/8” from the weld or 3/16” from the O.D. of the flange. Minimize air currents in the welding area to prevent disturbance of the gas atmosphere. Monitor temperatures at critical points using thermocouple detectors, ensuring they do not exceed 225°F. If using non-water-cooled heat sinks, remove them promptly after welding and air cool the bushing.
- Observe Installation Clearances and Post-Welding Handling
Maintain a clearance of 3/16” ± 1/16” between the epoxy shank and the mounting hole. Ensure the enclosure cover thickness does not exceed 1/4”. Verify the oil level covering the immersed stud connection is greater than 2 inches. Minimize forces applied to the heated stud and flange during handling before and after welding. Do not apply torque to the epoxy when making any bus bar connection. If thermal baking is required for equipment finishes, ensure the bake sequence does not exceed 130°F or 8 hours, and do not mechanically load bushing metallic contacts during this process.
