Notching of ties to allow for the performance of a thermite weld is:

Notching of ties to facilitate a thermite weld is prohibited due to the structural integrity and strength requirements of welded joints. Notching can significantly weaken the material, creating stress concentrations that may lead to failure under load. The purpose of the thermite welding process is to create a strong, continuous joint that ensures optimal load transfer and overall durability.

Instead, the surfaces to be welded should remain intact and properly prepared to maximize contact area and minimize defects, allowing for the chemical reaction in thermite welding to produce a high-quality, robust weld. Adhering to these guidelines is essential in maintaining safety standards and ensuring the longevity of the welded connections in various applications.
