Automatic Spot Welding of Ventilation Spacers on Lamination Sheet Using Robotic Work Cell

Deepak Sachan, Avinash Patil, and Subrata Biswas
Abstract—Stringent production targets, competition in global market and reduced man power have highlighted the need for automation in all major work areas of manufacturing organizations to gain higher productivity. As the demand for power is increasing, power equipment manufacturing companies need to make more efforts for automating core technology areas for productivity improvements. Spot welding of ventilation spacers for generators is one such area which can benefit heavily from automation from automatic robotic welding process. Ventilation laminations are required for cooling the stator core of the steam turbine generator and are manufactured by welding ventilation spacers on a lamination sheets using resistance welding (spot welding) process. The present paper proposes an automated apparatus and a method for spot welding of ventilation spacers on lamination sheets of various ratings of turbo generators, using a robot that holds and moves the work piece at a fixed spot welding machine to improve the productivity and quality of welds.

Index Terms—Automated spot welding, robotic spot welding, fixed spot welding machine, ventilation spacers, turbo generator.
