Precision in Fastening: The Crucial Role of Auditing Techniques for Error Elimination and Enhanced Process Results

Eliminating fastening errors hinges on employing proper techniques and tools. It is imperative to recognize that a process is considered under control until variances from the expected results are detected, prompting the need for an audit discussion. Contrary to assuming a lack of auditing, it is, in fact, essential.

The pivotal question arises: Even with proper joint design and torque application, how can we ascertain if the installed fastener aligns with the designer's specifications? The answer lies in auditing, a process employed for validation, information gathering, and confirmation. The term "audit" holds similar definitions whether used as a noun or a verb.

As a noun, it refers to the inspection or examination of a structure to assess or enhance its appropriateness, safety, efficiency, etc. For instance, an energy audit can propose ways to reduce home fuel bills. As a verb, it signifies making an audit of a structure to evaluate or improve its safety, efficiency, etc.

Even the most advanced fastening systems necessitate torque calibration for accuracy and repeatability. Thus, auditing becomes a crucial inquiry, providing insights into the job's execution even when the process is seemingly controlled flawlessly. Auditing serves as a preventive quality measure, mitigating potential failures and avoiding additional costs associated with errors.

Given the variability in joints and the challenges of achieving exact tension, Torque Auditing has its pros and cons. Traditionally, three main audit methods prevail: first movement in the fastening direction, first movement in the loosening direction (breakaway), and determining the rotation angle by marking the fastener, loosening it, and assessing the torque needed to return it to the original position. While effective, these methods come with drawbacks.

First Movement Testing:

• This involves using a hand torque device to observe the initial movement. The challenge lies in accurately "feeling" the first movement, making it difficult to observe. This method provides an estimate of current torque but lacks information on the movement required to achieve the desired torque if the current torque is insufficient. Incorrect execution can significantly increase joint load.

Breakaway — Loosening Direction:

• This entails a loosening test of the fastener, generally less than the actual torque. However, it may not be practical in live system audits due to the risk of leakage. Incorrect execution can result in improperly tightened joints, leading to more issues than solutions. It is ineffective when locking compounds or other security devices are employed.

Mark, Loosen, and Retighten:

• This test involves marking the bolt and application, loosening, and retightening. While practical, it provides no indication of the torque required if the current torque is insufficient.

The objective of auditing is to enhance process results, necessitating the collection of relevant information for evaluation and analysis. An audit that fails to provide pertinent insights into improving the fastening process is rendered ineffective. Practical experimentation may be required to achieve proper torque, and data is vital for such endeavors. Depending on the audit strategy, torque testers, torque sensors, dial wrenches, and digital torque wrenches can be employed for the auditing process efficiently and independently.
