The main beam inspection work of the double girder crane is ‘satisfactory’

       With the continuous development of the social economy, the improvement of production efficiency of various enterprises has been widely concerned by all sectors of society. The existence of double-girder cranes is an important equipment for the transportation of goods in many enterprises on the market today. The basic main beam inspection of double-girder cranes Work, I hope you can easily understand the following specific knowledge.

       The welding process of the butt weld of the main beam is complicated, and it is prone to defects such as incomplete penetration, inclusions, pores, hot cracks and cold cracks. In particular, the thermal stress generated by the butt welds may endanger the connection with the weld. Microscopic defects in the edge of the base metal, such as diffuse inclusions, uneven intergranular structure, etc. These microscopic defects will expand under the action of welding heat, resulting in strong thermal stress at the joint between the weld and the base metal. When the stress reaches the stress that the material itself cannot withstand, the steel plate and the weld will have macro cracks or delays. Cracks, so non-destructive testing of the main beam of the crane is one of the important aspects to ensure the quality and safety of the main beam.

       After the non-destructive testing of the welding quality of the butt welds of the steel plates of the double girder cranes, the problems caused by the welding can be completely avoided, and the operator can operate with great care.

       According to the above method, the basic main beam inspection of the double girder crane is carried out, which provides support for improving the use effect of the equipment and ensuring the improvement of the production efficiency of the enterprise.
