The highest population of robots is in the area of welding. Spot welding is a very tiring job for operators and the productivity is very low. MIG and TIG welding applications require a lot of skill and the smoke and light are hazardous.
While spot welding is mostly restricted to automotive BIW applications, MIG welding is most popular for sheet metal fabrication. 7th axis systems can be used to extend the reach of the robot. Rotary positioners can also be added to make the component accessible to the robot. For these applications, the input components need to be very consistent and clamping fixtures need to be thoughtfully designed.
Today there are several advanced features like seam tracking and vision based welding where feedback is provided and the robot automatically adjusts the path to make up for variation in the input components. These are expensive options and are to be used as a last resort.
For welding, we offer complete solutions with component fixturing and safety interlocks. Our solution at one of the OEM’s involves an OH Gantry system for welding large sheet metal components used for textile machinery manufacturing.
We also have a lot of knowledge in spot welding applications which was gained while working for General Motors in the USA.
