Thermal simulation modelling of substrate material during laser cladding process of thin section components

Abstract

In this master’s thesis work thermal simulation model creation for cladding process is being gone through. First thesis work goes through basic principles of laser technology and going more deeper into theories of different laser types, properties and benefits of use.

Thesis states out actual customer needs for thermal simulation tool to be made into their manufacturing process. Need for thermal analysis tool is to be able to estimate and prognose maximum temperature levels during customers manufacturing process with directed energy deposition process. Customer requirement was at first hand that simulation tool, model should be as accurate as possible for temperature prediction. Also, model should be adaptable to various shapes and sizes of components to be processed.

Simulation model calibration, build-up was made with constant communication with customers production unit. Tests during calibration model build-up phase were possible and were made, this to achieve as good simulation model as possible.

Validation tests were performed for finished simulation model at customers production unit. Results form validation tests were accepted by customer.

Future needs for further development are explained.
