Although the practice has declined over the years, lead welding (also, and somewhat erroneously, referred to as lead burning) is commonly used in applications like roofing, pipework and in the manufacture of acid-resistant tanks where conventional steel tanks may be susceptible to corrosion. There are two types of lead found in commercial welding:
Battery cells are most often put into modules or packs when produced for electrically driven vehicles. The variable of greatest influence when welding battery packs is the contact resistance between the cell and the connection tab. It is crucial to minimize this variable as much as possible to prevent energy loss in the form of heat generation.
