The Next Generation of Micro Welding

The Percussion Welder consists of two components; a power supply and weld head.

The power supply provides the weld energy and control of the weld process.

The weld head holds and aligns the weld materials and brings them together to forge the weld.

Controls allow operators to select accurate actuator velocity, timing delay, weld voltage, capacitance, polarity, and pulse width to effectively weld a wide range of materials.

Frequently Asked Questions

1. Can Percussion welding be automated?

A. Yes, the Percussion Welding process has been used in automation for decades. The traditional types of materials handling systems used in transport and placement of small components are used for percussion welding systems.

2. What is the size range for materials to weld?

A. The majority of percussion welding applications involve one material with a diameter or dimensions of .050” or less. The other material may be of equal size, smaller size, or larger size. Examples include two 18 AWG stranded copper wires butt welded together, another may be an 18 AWG stranded copper wire butt welded to a plate of stainless steel.

3. What equipment is required to make up a Percussion Welding System?

A. The standard Percussion Welding system is made up of two components the 858 Percussion Welder and the 726 Bench Fixture. In many cases specific wire holders or jigs are designed to accommodate unique part shapes.

4. How do I know if Percussion Welding will work for my materials?

A. Start by contacting MTI MicroWelding personnel at 303-536-7838 or email at MTI staff will assist you to assess the compatibility of your weld materials and to prepare tests of those materials.

5. Can Percussion welding be used to weld insulated wires?

A. Yes, joining insulated wires is done by attaching a ground clip to the opposite end of the insulated wire.

6. Can stranded wires be welded in a butt weld orientation?

A. Yes, because of the low impact force required in percussion welding, materials with very low columnar strength are easily joined

7. How can I become proficient in Percussion Welding?

A. MTI offers training courses of various length and depth to meet your individual needs.
