Development of an Analogical Model for Strain Monitoring of Welded Joint Regions During Uniaxial Tensile Testing

Abstract

The idea behind the idea of developing this method was to introduce reference points at important locations, such as the fusion line and heat-affected zones, the displacement of which would be monitored during the uniaxial testing, and then measured at key moments. The uniaxial tensile test process was recorded with a high-resolution camera so that changes could be observed during the test. The reason why this approach was chosen was that the crucial zones could be adequately marked and thus allow the allocation of the appropriate frame in order to monitor the strain of each welded joint zone individually.
