Automated Spot Welding Assembly

To achieve our customer’s goals MWES provided them with a welding assembly cell that included two separate fully-enclosed automation machines. One machine would handle welding three louvers onto a baffle plate, while the second machine would handle welding two diverters onto a baffle plate. Both machines are equipped with a six-station indexing dial and a pair of Milco C-type dual weld guns at three stations. The machines also include pneumatic automatic unload and reject chutes.

Both machines perform their respective operations in a similar sequence. With the louver welding machine, the operator loads the three louvers and the baffle plate onto the fixture at the first station. At the diverter welding machine, the operator loads two diverters and the baffle plate onto the fixture at the first station. Once the parts have been loaded the operator initiates the system via the HMI.

The dial on both machines indexes to the second, then the third and finally the fourth stations. At each of those stations, the dual weld gun automatically applies welds at the predetermined spots on the part. The fifth station is a buffer. At the sixth station, the completed part is pneumatically picked up and unloaded into a parts bin.
