Definition of capacitive solar container weld

What is Capacitor Discharge Welding (CD welding)?

Capacitor Discharge Welding (CD welding) is a fast form of resistance welding that utilizes capacitors to deliver power to the part. Capacitors are charged with large amounts of energy, which is then rapidly released into the parts within milliseconds.

Why is a capacitor used in welding?

A capacitor is used in welding to store electrical energy that can be rapidly discharged during the welding process. This discharge provides a high-intensity current flow, generating the heat required for melting the metal surfaces and forming a weld joint.

How does a capacitor discharge weld work?

Capacitor Discharge Welding works based on the principle of discharging stored electrical energy from capacitors through the workpieces to create a weld. The capacitors store a high voltage charge, which is discharged through the weld zone, generating an intense current flow for a short duration. The equipment used in CDW typically includes:

How many capacitor banks can be used for CD welding?

KAPKON Conventionally, a single capacitor bank is used for CD-welding. KAPKON offers this as a single-pulse technology (SP). KAPKON is the only manufacturer on the market to have further developed the capacitor technology that up to four independent capacitor banks can be used for welding.

What is capacitive discharge welding (CDW)?

Capacitive Discharge Welding (CDW) is a similar process to RSW except large amount of energy is released in relatively a short amount of time. A research group at The Ohio State University working under supervision of Dr. Menachem Kimchi and Jerry Gould from EWI has investigated the feasibility of Al/Steel joining via this process.

What is CD welding?

The electrodes are the contact points through which energy transfers to the materials. They play a critical role in the overall quality of the weld. Due to their heat and electrical conductivity properties, tungsten or copper-tungsten electrodes are common. CD welding stands out among other welding techniques for its unique set of advantages.
