Cold curing adhesives

Cold curing adhesives are easy to use and can be processed at minimum cost and eff-ort since they harden under normal ambient conditions. If they feature short curing times they are also called superglue. The preferred eld of application is in experi- mental stress analysis. However, if the temperature around the measuring point is hig- her than about 80C, we recommend to use a hot curing adhesive or a heat resistant, cold curing epoxy resin adhesive (280).

Spot weld joints

Spot weld joints are only possible with the special strain gage of type LS 31, and if the test object is of a weldable material. This method is particularly suitable for applica- tions where the cleanliness required for bonding cannot be guaranteed. Hardly any pre- parations are necessary and the installer needs very little previous experience. However, it is essential to follow the process instructions supplied with the strain gages.
