Through what angle are the daily startup test studs to be bent, assuming 360 degrees of flash?

In welding procedures, particularly when considering daily startup tests for equipment like welding machines, the angle to which test studs are bent is critical. A bend of 30 degrees is commonly used to ensure proper evaluation and operational verification of the equipment. This angle balances the need for a significant measurement without causing undue stress or damage to the welding studs.

The standard of using a 30-degree angle serves as a practical threshold for assessing the performance capacity of the equipment while accounting for a flash allowance of 360 degrees. This allows for sufficient margin in evaluating the integrity of the weld or joint being tested. Using too shallow an angle may not provide an adequate assessment of the equipment's performance, while a steeper angle could lead to unnecessary wear or misrepresentation of the machine's capabilities.

Therefore, 30 degrees provides an optimal point for ensuring the startup tests are reliable, and it aligns with industry practices for performing such evaluations in welding operations.
