Speed

400 ms blink

< 2 ms weld

Seriously fast and seriously strong. That speed is why the heat-affected zone stays tiny and why there is never a need to crimp and solder.
Slow motion: copper wire percussion welded to stainless steel.

Two metals are loaded with their weld points brought to a pre-defined gap.

The process

Four stages. Under two milliseconds.

Why it's different

< 2 ms

Start-to-finish weld

The entire forge-welding action takes less than 2 milliseconds. A blink takes 400.

0

Consumables

No filler, no solder, no flux, and no electrodes to wear out.

≈ 0 Ω

Electrical resistance

A direct metal-to-metal bond with near-zero resistance across the joint.

HAZ

Minimal heat-affected zone

Arc heating lasts milliseconds, so nearby parts and material hardness are preserved.

Pull test

The wire breaks first

In pull tests the wire often breaks before the weld does. Resistant to shock and vibration.

On the bench

Slow motion: percussion welding a screw to a washer, a common micro weld for automotive components.
18 AWG copper wire percussion welded to a stainless steel tube.

FAQ

What is percussion welding?

A heat-plus-impact process for joining metals.

An electric arc supplies the heat, then a rapid mechanical movement forces the two materials together, forming a full metallic bond with no filler.

How fast is a percussion weld?

Under 2 milliseconds, start to finish.

A human blink takes about 400 ms. The arc itself heats the parts for only a few milliseconds, which is why the heat-affected zone stays minimal.

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.

Do I need filler metal, solder or flux?

No. There's no filler, solder or flux, and no electrodes to wear out.

That means cleaner joints, less waste, and no consumables to buy.

Is it possible to automate the Percussion Welder process?

Absolutely.

Percussion Welder can use the same materials-handling systems other micro-welders use to transport and place small components. Give us a call — we can share many examples where it was successfully automated.

How can I become proficient in using the Percussion Welder?

It's easy to learn and intuitive to operate.

We also offer training courses tailored to your specific applications — only what you'll actually use, so you're successful now and in the future.
