6 FAQs about [Spot welding of energy storage electrode plates]
What is a spot welding setup?
The basic spot welding setup consists of a power supply, an energy storage unit (e.g., a capacitor bank), a switch, a welding transformer, and the welding electrodes. The capacitor bank acts as a supplier of high instantaneous power levels. The accumulated energy is dumped into the welding transformer when the switch is pressed.
What is spot welding a battery?
To create batteries, spot welding is also used to attach straps to nickel-cadmium, nickel-metal hydride, or lithium-ion battery cells. Spot welding thin nickel bands to the battery terminals connect the cells. This method prevents the battery from overheating, which could occur if traditional soldering was used.
What is spot welding used for?
Spot welding is also utilized in orthodontist clinics to resize metal “molar bands” used in orthodontics with small-scale spot welding equipment. To create batteries, spot welding is also used to attach straps to nickel-cadmium, nickel-metal hydride, or lithium-ion battery cells.
What type of electrode is used for spot welding?
Because of the high electrical and thermal conductivity of aluminum, RWMA recommends Group A Class 1 electrodes which are more conductive than the Class 2 electrodes so common with spot welding of steel. A variety of electrode geometries may be used, but the Type “F” radius electrodes are generally the most common.
What is a resistance spot welding setup?
The resistance spot welding setup mainly consists of tool holders and copper alloy electrodes. The tool holders act as a mechanism to hold the electrodes firmly in place and also to support the cooling water hoses that are used for cooling the electrodes.
How many fused spots does a RSW weld cycle produce?
Each electrode contacts a single piece of base material. Each (+) weld cycle produces only one fused spot. Series Welding –RSW utilizes two electrodes positioned adjacent to each other but separated by an air gap or other dielectric.
