Predictive modelling of the penetration coefficient of cold metal transfer welded joints using machine learning approaches

Autor: Nalajam Pavan Kumar, Ramesh Varadarajan

Publikováno v: PROCEEDINGS OF THE 14TH ASIA-PACIFIC PHYSICS CONFERENCE.

Weld bead geometry is an important characteristic of the weld joints in evaluating its quality. However, weld geometry is characterized by three parameters namely weld width, weld height and weld depth. The measurement system of three parameters is o
