Abstract:
In present study
pattern recognition of weld joint is studied for welding process
control, with linear CCD as sensor. A N-dimensional state vector
is proposed by the authors to describe the image figure and a
4-dimensional characteristic feature vector is extracted from it
for recognition of the cross section contour of the welding
joint. Instructions are then generated according to the
characteristic feature vector of real-time control of the torch
position and parameters of the welding process.
Key words:
