What Methods of Quality Control are used in FrictionWelding?

Frequently Asked Questions

Most production friction welding applications employ 'in-process' monitoring of the major weldingconditions as a Quality Control Method which for continuous drive rotary friction welding include: -

Rotation speed Friction force Axial displacement (shortening of the two components) Forge force

A machine shut down facility or alarm system can be operated by the monitoring system if incorrectwelding conditions are indicated, thus avoiding poor weld quality. However, not only are the weldingconditions monitored but, Quality Control starts with the raw materials to be joined and the followingshould be checked:

Chemical analysis Microstructures Strength and hardness Dimensions, tolerances As supplied condition

Following these checks the dimensions of the component are measured for compliance with thespecification, and the surfaces are cleaned for welding. The tooling or clamping fixtures holding thecomponents to be welded should also be checked for:

Accuracy of alignment Excessive clamping forces Permitted overhang from the fixture

A welding procedure (in accordance with BSEN ISO 15620:2000) is usually agreed between contractorand customer, which will usually involve most of the aforementioned topics. Weld procedure approvalusually requires that destructive testing be undertaken after the production of an agreed number ofwelds. In the event of failure during bend or tensile tests then preceding samples will also be testeduntil the source of failure is isolated.

Ultrasonic testing has been applied to friction welded components and techniques are being developedwhich are said to be capable of detecting non-welded regions.
