How It Works While the amazing Cold Weld™ Electronic Spark Deposition Technology is very simple in function, here is a technical overview to better explain the process. 10-300 volts of direct electric current (DC) is generated from 120 VAC (standard wall outlet current) and is stored in a series of capacitors within the equipment. Controlling the release of this stored current is a PWM (pulse width modulator) which controls the release of the current in a 10% on, 90% off duty cycle discharge cycle, set at 50-60 hertz (cycles per second). As in any DC circuit, there is a cathode and an electrode. DC current always flows from the anode to the cathode, or + to -. The cathode, or ground, is connected to the workpiece. The anode, or electrode, contains the metal to be bonded with the workpiece. The electrode is attached to a vibratory or rotary applicator. The resulting movement causes the electrode to jump off of the workpiece when placed in contact with it, forming a small gap between the electrode and the workpiece.. When a gap is formed, the electric current stored in the capacitors, exceeding a temperature of 25,000 C, is conducted between the electrode and the workpiece in the form of an electric arc. How wide this gap is controlled by the output voltage of the equipment and directly relates to the thickness of the coating. Due to this arc, a microscopic molten crater forms on the workpiece, the material from which is dispersed into the air (the yellow outgoing sparks you see in the pictures). At the exact same time, the very same process is repeated on the surface of the electrode, yet the displaced material from the electrode is attracted to and fuses with the workpiece. This electrode material instantly cools due to the surrounding cold workpiece. By this process happening at 50-60 times per seconds, a layer of the electrode material is deposited both within and on the surface of the workpiece. The list of applications for our exclusive Cold Weld™ Technology is nearly endless. Because this amazing process enables the metallurgical bond between nearly any two metals per single process without affecting the original characteristics (inherent hardness or toughness) of the base material, there are uses we have not even imagined yet and are busy exploring even as you read this. While the most common application is performed using the Cold Weld™ Carbide Electrode to increase wear resistance on steel tools and equipment, there are many other uses which we would love to discuss with you in more detail.
