Battery Tab Spot Welding System (Pneumatic Operation)

Fireweld delivers reliable results and allows you to create durable welds. This welding process is very economical as no addition of filler material is needed as the current is used through the electrodes. Another advantage of spot welding is that it makes point contact, so the welding area is confined to the limited weld area and only takes place exactly where the tip of the electrode touches. Thus, energy is concentrated and heat generation is reduced.

Due to the high energy density, lithium-ion batteries are now used in many fields such as electric vehicles, mobile and laptop devices, etc. A single battery cell cannot be used in a battery pack because its voltage and current density are not sufficient to operate.

Therefore, many battery cells must be assembled in series/parallel to form a battery pack assembly. As a result, nickel strips are required as electrical bridges between battery cells. For 18650 and other types of lithium-ion battery cells, a battery spot welder can be used to weld sheet metal connectors to the battery cells.

Our welding electrodes are made of a mixture of copper, chromium, and zirconium (CuCrZr), a triple welding electrode material used for spot welding stainless steel, copper, and nickel alloys in battery pack assemblies.
