Capacitive Discharge Welder Releases Energy Fast

Capacitive discharge welder is used in various applications due to its ability to release energy quickly. This type of a welder uses the large capacitors to store energy for fast release. The welds are formed using this energy and the material near the weld gets less heated as compared to other weld types. This way the metal properties are not affected by the heat. Only a small area near the weld is affected by the heating and the cooling process.

Due to the fast discharge rate of a capacitive discharge welder, it can be used to make welds in materials that are electrically and thermally conductive. These include metals such as copper and aluminum. The surface has to be thoroughly cleaned before the welding process. On the micro-scale surface bumpiness limits surface to surface contact. Contact resistance is low when there are more contact points. There are many more factors that affect contact resistance. When the contact resistance is large the resultant weld is hotter. On the micro-scale level when more contact points or metal bridges are formed contact resistance is reduced. By using more electrode pressure you can create more metal bridges. This makes for a cooler weld as contact resistance is low. When the electrode pressure is lighter the metal contact is less and this makes for a higher resistance and a hotter weld.

In direct welding, one electrode passes the current through both the surfaces that need to be welded and goes out from an opposing electrode. When you can access only one side of the work piece you have to use an electrode in both materials. In a series weld, you can place an electrode on one surface from one side and divide the current between the two parts to be welded. This requires more energy to form a weld.

The voltage of the welding capacitors has to be stable during the weld and a capacitive discharge welder is designed to control it. A little difference in voltage can make a big difference in the energy level which can distort the weld.

The CD125SP capacitive discharge welder by Sunstone has the energy adjustment knobs so you can easily control the voltage and adjust it to the needs of your application. There is another knob that lets you adjust the Pulse energy. It is adjustable between 3% and 100% of the total stored energy. You can also use the welder with an external power supply. The welders can be adjusted to its minimum and maximum energy.

When you have a need to weld surfaces get a capacitive discharge welder that suits your application best. The engineering service companies carry a large variety of welders for all types of welding jobs. You can also outsource all your welding jobs to them at an affordable rate.
