Percussion Welding Weld Schedules

Lab data

Weld schedules produced from experimentation with various materials in our labs — starting points to help you develop the schedule your application needs.

We strongly recommend varying a single parameter at a time and testing the result. That makes the schedules with the best strength and cosmetic appearance easier to find, and patterns appear during experimentation.

FAQ

Are these parameters ready for production?

They're starting points from our lab experiments.

Actual alloys and material masses vary, so final schedules come from small adjustments. Change one parameter at a time, test, and validate joint strength before production.

What do the capacitance settings mean?

Cap 1, 2 and 3 are the three capacitor-bank settings on the 858, and 1HD, 2HD and 3HD are the heavy-duty banks.

Higher banks store more energy per weld. The exact capacitance of each bank is listed in the 858 specifications.

How do I know if my materials can be welded?

Start with the Parameter Finder or the weld schedules table.

If your pair isn't listed, tell us your weld challenge. We'll reply with a straight answer about whether percussion welding is a fit, and how.

Which metals can it join?

Dissimilar combinations are the specialty — aluminum, brass, copper, steel, titanium and many more.

Our lab database holds 131 tested weld schedules across 33 materials and 68 material pairs. Don't see yours? We've welded hundreds of combinations and can develop a schedule for yours.
