Tests of Hot Crack Resistance Using the Transvarestraint Tests – Specialist Automated Test Rig
Journal Title: Biuletyn Instytutu Spawalnictwa - Year 2016, Vol 60, Issue 6
Abstract
The significance of the Transvarestraint test as one of the most reliable tests enabling the assessment of the susceptibility of materials and welds to hot cracking when exposed to imposed strains aimed to assess the susceptibility of steels and welds to solidification cracking as well as research-related needs inspired Instytut Spawalnictwa to develop, design, provide related software and implement an automated test rig examining hot crack susceptibility using the above-named method. The article presents the design and operation of the test rig. The adopted design and software solutions make the station user friendly as regards the entering of all data and welding head movement trajectory as well as the recording of data and measurement results in the form ready to print and archive. The solution also ensures the obtainment of the repeatability of the entire technological process.
