With this quick reference guide, SCS aims to strengthen awareness of holistic safety and ergonomics assessments while providing practical guidance for everyday industrial applications. Users receive a concise overview of
Why a Joint Analysis and a PCT (process capability test) of a bolted joint is required for product manufacturers. If you ask in the assembly department whether and how the users check their bolted joints AFTER assembly, there is often astonishment. Especially when already controlled, monitored and regularly tested tightening systems are used. "We assemble with high precision and monitor all parameters. Every year our tools are tested! Why should we still check the joint now? The tools always show correct values." A fallacy and source of quite a few quality defects and recourse claims in connection with bolted joints! In the following, you will find out why the analysis of bolted joints and the random execution of process inspections are so useful, why standards and guidelines specifically require them, and what the technical correlations are.
A tightening tool is a quite complex system – no matter if it is a torque-angle controlled EC-tool or a supposedly easy to use mechanical click wrench. If you look
Tighten a joint is an operation less trivial than you might think. Tighten a screw at the rated torque is not itself a guarantee of a proper tightening stable over
Tighten a junction properly is a fundamental step in ensuring the quality of a production process. At the end of the production line, there is a crucial step that needs
Automotive example What is statistical process control? Statistical process control consists in a set of statistical tests performed on a process (for example a production line). Its goal is to:
Tighten the joints properly on a production line is a fundamental step to ensure the quality on the assembly process. The selection and use of wrenches, electronic or mechanical, is
When using click wrenches, the torque applied to the bolt is higher than the value set for the click. This happens because the operator does not stop immediately after the
Pulse tools generate pulses instead of continuous torque: Pulse tools must be tested on a static transducer (standalone transducer connected to a torque measuring instrument or a test bench equipped
