Double Gider Welding Production

The main beam welding production of double beam bridge cranes usually includes the following steps: 1. Design and preparation: according to the requirements of the crane, design the structure and size of the main beam, and determine the required materials and welding process. Prepare welding equipment and tools. 2. Material preparation: Prepare the steel required for the main beam according to the design requirements. The steel is cut, trimmed and cleaned to ensure it meets welding requirements. 3. Welding preparation: According to the design requirements, the various components of the main beam are positioned and assembled. Use temporary welds or jigs to hold the parts in place. 4. Welding operation: According to the welding process requirements, the use of appropriate welding methods for welding. Common welding methods include manual arc welding, submerged arc welding and gas shielded welding. According to welding process specifications, welding current, voltage and speed parameters are controlled to ensure welding quality. 5. Post-welding treatment: After the completion of welding, check and clean the weld. Use appropriate tools and methods to remove welding slag and oxides, and perform necessary trimming and sanding. 6. Inspection and quality control: inspection and evaluation of welding quality. Use non-destructive testing methods, such as ultrasonic testing and X-ray testing, to check the quality and integrity of the weld. Ensure welding quality meets design and standard requirements. 7. Anti-corrosion treatment: According to the use of the crane environment and requirements, the welding parts for anti-corrosion treatment. Common anti-corrosion methods include spraying anti-rust paint, hot-dip galvanizing and coating anti-corrosion materials. 8. Final assembly: After the main beam is welded, it is finally assembled with other components. According to the design requirements of the crane, the main beam is assembled together with the bridge, lifting machinery and control system. 9. Testing and commissioning: After completing the assembly of the crane, testing and commissioning are carried out. Test the functions and performance of the crane to ensure its normal operation and safety and reliability. 10. Completion and delivery: After the completion of testing and commissioning, the final inspection and cleaning of the crane. Ensure that the crane complies with design requirements and standards. Ultimately delivered to the customer or put into use.
