Welding technologies in instrument manufacturing

Dr. Frigz International uses four different types of welding technologies throughout its manufacturing facilities. The choice of technology depends upon the material, profile of the workpiece, and technical requirement of the instrument.

Spot Welding: This is a form of electric resistance welding. Two brass electrodes are used to ‘spot weld’ together two sheets of metal that are placed on top of each other. Dr. Frigz uses this type of welding to create multiple ‘welding spots’ on the tail end of its tweezers (tissue forceps).   

Argon Welding: Dr. Frigz uses this technology for welding tungsten carbide (TC) rods onto stainless steel scissors. The TC instruments are more durable and premium and require excellent weld strength and finish.

Laser Welding: This is one of the latest forms of welding that uses pure laser source for heating and welding the elements. Dr. Frigz uses laser welding for two different reasons; for repair purposes of instruments, and also for assembly welding two different parts to the same instrument.  

Induction Welding: This is one of those mesmerizing technologies that a person can keep watching for extended time. Through this electromagnetic induction process, Dr. Frigz welds together Tungsten Carbide inserts to stainless steel instruments (forceps and needle holders).
