Project Description:
The practice of industrial welding has always been dependent on the
skill of the welder, which has made it more of an art than a science.
However, in the last two decades significant efforts have been made not
only to introduce automated welding, but also to ensure that automated
welds are of a sufficiently high quality. Modelling, sensing and
control of the automated welding process are vital to achieving this
goal.Gas Metal Arc Welding (GMAW) is one of the key welding processes
in industrial manufacturing. Thus, the modeling, sensing and control of
the GMAW process is vitally important. The research topics include
modeling of the GMAW process, including the physics of welding, weld
pool geometry, metal transfer characteristics and process voltages;
sensors for arc length, weld pool control and weld pool geometry,
including both optical and intelligent sensors; control techniques,
including PI, PID, multivariable, adaptive and intelligent control.
