Quality assurance for bolted connections
in accordance to DIN EN 17976
Safely apply quality assurance measures for bolted joints in rail vehicle manufacturing, evaluate assembly results, and analyze random samples in a practical manner.
That's what this seminar is about
Understand quality assurance in accordance with DIN EN 17976, reliably evaluate assembly results, and independently perform statistical analysis of bolting data.
Determine tolerance intervals
Apply tolerance intervals according to DIN EN 17976 and present measured values clearly using histograms.
Validate initial assembly
Validate the results of the initial assembly to ensure they comply with standards and evaluate them in terms of quality.
Ensuring quality over the long term
Selectively apply testing and monitoring procedures for safety-critical bolt connections.
ECM & Documentation
Requirements for the maintenance manual and work instructions understand and appropriately define the scope of ECM functions.
