In general, the Bend Test of the Railway Welding Service is an important component of railway construction and maintenance. This helps to ensure the safety, reliability and longevity of rail connections, ultimately contributing to the safe and efficient operation of rail systems.

The bending test involves the application of a controlled force to the rail joint. This force is usually applied by hydraulic or mechanical means and gradually increases until a certain deflection level is reached.

Bend test results inform maintenance planning by identifying rail joints that may require repair or replacement to prevent potential rail failures.
