What are the important aspects of Tab welding?

From a welding perspective, the important aspects of tab welding are the thickness and material of both the tab and the terminal. Resistance welding is extremely well suited to welding nickel tab material up to 0.015-inch thickness, and nickel or steel clad copper tab material to around 0.012-inch thickness to a wide variety of terminal materials.

Can a laser weld a tab to terminal?

Due to a different welding mechanism, laser welding is able to weld both thin and thick tab materials, with a capability of welding copper or aluminum tab material above and beyond 0.04-inch thickness. Avoiding penetration of the can and overheating the battery are important aspects of tab to terminal welding.

What is tab to terminal welding?

Avoiding penetration of the can and overheating the battery are important aspects of tab to terminal welding. Welding tabs or terminal connections to buss bars generally does not require as much penetration of heat input control as the tab to terminal welds.

Do weld tabs require heat input control?

Welding tabs or terminal connections to buss bars generally does not require as much penetration of heat input control as the tab to terminal welds. The materials, material thickness and combination of materials determine the best welding technique.

What is tungsten inert gas welding?

Similar to resistance welding, tungsten inert gas welding (TIG), also known as gas tungsten arc welding, has been used in manufacturing for many decades and has traditionally been used for the more challenging welding applications for nonferrous materials.

What is resistance welding?

Resistance welding has been an established joining technology for more than 40 years and has been used in the battery industry for almost as long. Since then, a steady stream of advances in resistance welding systems has given users significantly improved capabilities to control various aspects of the process.
