Study and Fabrication of Virtual TIG Welding Equipment
The green technology is applied in training welders by using simulation equipment. The virtual tungsten inert gas welding (TIG welding) equipment permits of reducing the cost of welding practice training by saving on materials, electricity. It does not cause the environmental pollution. It is not harmful to welding learners. This paper studies on the permissible range of technological and technical parameters of TIG welding process. This is basis to develop the software in order to evaluate learners on virtual TIG welding equipment. These are foundations to manufacture the virtual TIG welding equipment. This equipment allows welding learners to practice the basic operations and skills as on real TIG welding machine, including the techniques of striking the arc, restarting the arc, maintenance of arc length, controlling of torch angle, filler rod angle, the operations of torch move, filler rod move,... with different welds and different positions
