Multi-head Spot Welder

Manufacturing initiative to improve process capability.

Key Attributes

• 11 cylinder design combines two lengthy spot welding processes into a single short one.

• Final MIG welding step integrated into work cell to minimize WIP/eliminate waste.

• Customized fixturing allowed for easy loading and precise, repeatable welds.

• Timeline/Budget: $70,000; 3 months

Highlighted Problem and Solution

• Loss of current in the middle welds which resulted to poor joints; attributed to induction losses.

• Switched to push/pull wiring to minimize surface area of electrical loop.
