Micro-wire energy storage welding

Is micro-Tig a good welding material?

Micro-TIG offers excellent welding of copper, and so presents a good solution for buss bar welding that would require a brazing material for resistance welding or a large power laser welder. Both butt, fillet and lap welds are possible up to and beyond thickness of 0.02 in thick copper are routinely welded.

Can You weld copper with micro-Tig?

Both butt, fillet and lap welds are possible up to and beyond thickness of 0.02 in thick copper are routinely welded. When welding copper using micro-TIG it is extremely important to use a pulsation function that creates the weld without porosity, as show in Figure 3.

What is the difference between micro-Tig and laser welding?

This process became known as micro-TIG, a generally non-contact process that offers excellent copper joining while offering a fairly relaxed process window with respect to part fit-up and positioning tolerances of the electrode to the parts. Laser welding is a newer technology, introduced in the manufacturing marketplace in the mid-1980s.

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.

What materials can be welded with laser welding?

For tab and buss bar joining, laser welding offers a high degree of flexibility, welding both thin and thick tab materials, and materials such as copper, aluminum, steel and nickel as well as dissimilar material combinations. Two example welds are shown in Figure 4.

What is laser welding?

Laser welding is a newer technology, introduced in the manufacturing marketplace in the mid-1980s. As laser technology has matured, and the awareness of its benefits spread, it has become an established process. Today it is simply another tool in the manufacturing engineer’s toolbox to be used and implemented as needed.
