Electrode temperature of energy storage spot welding machine is high

What is a resistance spot welding s Tup?

ntain the pressure to allow the weld metal to cool and solidify. The applied weld times normally range from 0.01 to 0.8 s depending on the thickness of the m tal, the electrode force, and the electrode tip diameter [2, 3].The resistance spot welding s tup mainly consists of tool holders and copper alloy electrodes. The tool olders ac

What is a spot welder used for?

of larger, more powerful, and more costly welding transformers.Spot welding is most commonly used in the automobile manufacturing business, where it is nearly routinely used to join the sheet metals of car frames. Spot welders can also be fully automated and many o

What types of electrodes are used in spot welding?

that are used in spot welding also vary in terms of their uses. For high heat applications, radial type electrodes are used, truncated tip electrodes are used for high pressure, eccentric electrodes for welding corners, offset eccentric tips for reach-ing into corners and narr

Why is spot welding important?

d electrical conductivities necessitate larger welding currents. This necessitates the us of larger, more powerful, and more costly welding transformers.Spot welding is most commonly used in the automobile manufacturing business, where it

Why do welding electrodes have a contact resistance?

ding, cables, and welding electrodes all have their resistances. The contact resistance b tween the welding electrodes and the workpiece is also a factor. There’s also the resistance of the work-pieces and the resistance of the workpieces’ contact. Because contact resistances are typ

What is resistance spot welding?

body of automobiles, which are numerically controlled nowadays. Resistance spot welding works on the principle of Joule’s law of heating, where the heat generat d is directly proportional to the square of the welding current. This welding technique is generally used
