Weld metal revelation for machine vision applications
Abstract:
Modeling and optimization of welding processes is one of the
important topics for welding researches. In such research, it is necessary to
measure the weld bead geometry. Nowadays, machine vision has a widespread use
in measurement applications. In order to use machine vision in weld bead
geometry measurement, it is necessary to acquire the desired images of cross
section of welded plates with desirable separation of weld and base metal
regions. This separation is performed by suitable solution to etch cross
section of welded plates. In this paper, it has been tried to determine
suitable solution to etch cross section of welded plates (made from API X56
steel) for obtaining the best revelation of weld metal
