Lighting weld test

16 May 2019

Solution

  • Motorised tensile test system and digital gauge
  • Wedge grips for grasping the terminal pins
  • Rubber-coated pegs for securing the light specimen

Benefits

  • Repeatable and accurate test routine
  • Clear peak load result indication
  • Simple, low-cost solution

Requirement

A simple, low-cost fixture was specified by the customer for the Quality Control Laboratory. This was to hold a lighting assembly in a test where the welded contacts were pulled off.

A Motorised Test System was specified as the test needed to be repeatable and accurate.

Solution

A multi-purpose Small Wedge Grip was used to hold both electrical contacts. The bulb assembly was held inside a mounting fixture attached to the Motorised Test Stand.

To prevent point contact and possible damage to the bulb assembly, 2 pegs with rubber sleeves were used to secure it. The contacts were pulled to destruction at a test speed of 50 mm/min with peak load being captured at a fast rate of 1200 HZ to ensure a high degree of repeatability between tests. A cable between the AFG and VersaTest Stand was used to automatically reverse the crosshead of the stand to its start position after the contacts were broken.

Test equipment

  • VersaTest Motorised Test Stand (superseded by the MultiTest-dV series)
  • 1000 N AFG
  • Bulb Assembly Mounting Fixture
  • Small Wedge Grip
