How to weld the fixing bracket for the vertical shaft cable tray

Weld the fixing bracket by temporarily positioning it, ensuring alignment, and performing welding according to approved procedures and safety standards.

Step-by-

Step Procedure1. Select the Welding Position Identify the exact location on the vertical shaft where the cable tray bracket will be installed. Ensure the position aligns with the overall cable tray layout and load requirements, maintaining proper spacing from other supports and expansion points.

2. Temporary Attachment Temporarily secure the bracket using clamps or a joint surface on the lower plate. Some methods use a synthetic rubber adhesive on the bracket's base to hold it in place, allowing a single operator to manage the welding without additional personnel.

Ensure the bracket is plumb and level before welding. 3. Prepare the Surface Clean the metal surfaces of the bracket and shaft to remove rust, paint, or debris.

Use a grinder or metal brush to ensure a clean bonding surface, which improves weld quality and strength. 4. Welding Setup Use a welding machine suitable for the tray material and thickness.

Equip yourself with proper electrodes, welding torches, and safety gear, including gloves, helmet, and protective clothing. Ensure the power supply matches the welding equipment requirements. 5.

Perform the Weld Weld the bracket to the vertical shaft according to the approved Welding Procedure Specification (WPS). Apply consistent heat and maintain proper weld bead size to ensure structural integrity. For vertical installations, tack welds may be used first to hold the bracket before completing the full weld.

6.

Inspection and Touch-

Up After welding, inspect the joint for defects such as cracks or incomplete fusion. Grind any sharp edges and apply touch-up paint to prevent corrosion, especially if the bracket will be exposed to environmental conditions. 7.

Final Alignment Check Verify that the bracket is correctly aligned and securely fastened. Ensure the cable tray can be mounted without stress or misalignment, and that all safety and load requirements are met.
