The recommended method involves temporarily attaching the cable tray side to a stable surface and performing welding at the selected position, often using a joint surface with synthetic rubber adhesive to improve convenience and reduce labor.

Step-by-Step Welding Procedure

1. Select the Welding Position Identify the exact location on the cable tray side where welding is required. This ensures proper alignment and structural support for the tray system .
2. Temporary Attachment Temporarily attach the side of the cable tray to a stable surface, such as the floor or a support frame. A joint surface on the lower portion of the tray, often coated with a synthetic rubber adhesive, can be used to hold the tray in place during welding . This step allows a single operator to perform welding without additional personnel.
3. Perform Welding Weld the side of the cable tray to the support structure or adjoining tray components. The welding should be done along the preselected welded portions, ensuring a strong mechanical connection. The method described in KR20150027452A allows for operator-only welding, improving efficiency and reducing labor costs .
4. Check Alignment and Quality After welding, verify that the tray side is properly aligned and that the welds are continuous and free of defects. This ensures the tray can safely support cables and withstand mechanical loads, including those generated during short circuits .

Additional Considerations

• Material Compatibility: Ensure the welding method is compatible with the tray material, such as steel or aluminum, and consider corrosion resistance if the tray is exposed to environmental factors .
• Safety Standards: Follow relevant standards such as BS EN 61537 for cable tray systems and BS 6946 for channel supports to ensure compliance and safety .
• Labor Efficiency: Using temporary adhesives or joint surfaces reduces the need for multiple operators and simplifies the welding process .
• Inspection: Post-weld inspection is recommended to confirm structural integrity and adherence to installation guidelines . By following this method, welding the side of a cable tray becomes more efficient, safer, and compliant with standard installation practices, while minimizing labor requirements and ensuring reliable cable support.
