In this case, the challenge was to clamp the parts to eliminate the twist. This automobile hauling trailer manufacturer needed to robotically weld 10 different aluminum part numbers ranging from 46” to 99” in length on the same fixture. These aluminum parts, notorious for heat distortion, needed to be flat after welding.

The solution was a precisely designed, shimmable fixture that clamped the parts effectively, while not interfering with the robot’s ability to make all required welds.  While this fixture design challenged our team – we’d never tooled a part just like this before, our experience allowed us to anticipate the problems inherent in welding these parts.  After seven years, the customer is still using this fixture to produce some of the best parts they’ve ever made.
