Thermocouple/Fine Wire Welding Machine
Impulse Welding is an ultra modern way of metal joining which replaces many other techniques such as riveting, soldering or conventional AC welding.
In the Impulse Welding, the required electric energy is stored in a CAPACITOR BANK, which is charged during the intervals between the two welds. As the charging takes place quite slowly there is a great saving on power supply as compared to conventional AC welding machine. Also there is no sudden heavy burden (surge) on the mains, creating problems to other machines.
The actual welding time is only a few Milliseconds (Tentatively 5 to 8 mSecs) long so that only the very
welding zone is heated up, while neighboring zones remain practically cold. There is no distortion, tarnish or annealing of metal around the welding zone. Welding time is so short that sufficient melting heat is produced in the welding zone, before heat dissipation, a state which is unavoidable with longer welding times. This also means that the total amount of heat applied is as small as possible as - hardly higher as the necessary for the weld itself. The welded parts stay practically at room temperature.
The high currents from Impulse Welders make this method applicable even for metals of high electrical and thermal conductivity such as copper, silver and even platinum.
With Impulse Welding machines, electrode cooling is not required even at very high production rates, Electronic stabilized charging along with proper feedback keeps the voltage across the capacitor absolutely constant and gives constant welding energy even at power line variation and with that highly reproducible welding results.
With the negligible short welding time, production speed is limited only by the time required for feeding in parts to be welded; this time is sufficient for recharging the required capacitor banks.
Welding is done on the job by placing the job in between two electrodes. The machine comes with Two types of fixtures
- Manual Weld head: Two electrodes are manually pressed by keeping the job in between.
- Pneumatic Weld head: Two electrodes are Pneumatically pressed by keeping the job in between.
