Smart Bridgewire Welding
SMAC Moving Coil Actuators and Bridgewire Welding and Soldering
In welding, maintaining the proper distance as the weld melts is critical.
SMAC Advantages for Welding and Soldering:
- Consistent and even welds.
- Apply pressure without breaking the surface.
- Performs a task and provides analytical data so that you can monitor the task was done correctly the first time.
- Utilizes SMAC's patented Soft-Land.
Case Study: As an example, SMAC actuators were used to do wire welding on air bag ignitors. Previously, the manufacturer had a weld tip attached to a spring tab. An air cylinder holds the spring tab up, during the weld cycle and the cylinder moves out from under spring tab which then applies a set force on the wire to weld. SMAC was already doing this kind of application successfully with an OEM so the manufacturer gave SMAC a try.
Each part change required a mechanical set-up of precise distance from the weld surface. Many parts can be ran before an error was caught. The SMAC Solution was to use an LCS25-010-52 to move the weld tip up and down, which eliminated the spring tab and air cylinder, eliminated the mechanical adjustment with part change because the LCS25 uses a Soft-Land on the part so relative position up for home is automatic, and the force applied was programmable for quick dial-in results. Customer ran weld tests using 2 actuators on a line machine. Test results were very successful.
