PLASMA AND LASER ENHANCED ARC WELDING FOR AUTOMATIC APPLICATIONS

Objective

-To study the underlying physical mechanism of the welding arc.
-Investigate energy distribution and transfer between the arc and the weldpool for both partial penetration and keyhole geometries.
-Determine operating parameters for positional plasma keyhole welding.
-Examine the influence of laser beam enhancement on arc stability, weld quality and productivity.
-Determine the role of radiation on arc structure and energy transfer efficiency.
-Construct theoretical simulations of the arc welding process as a basis for future model development.
-Improve ignition behaviour and stability of the arc by using a laser beam as support.
-Determine operating parameters for positional laser enhanced are welding.
-Prepare a laser enhanced arc welding facility, using a laser of a comparable low power (lower than 300 W).
