The purpose of this project is to conduct a comparative literature study of different welding techniques for welding batteries. The compared techniques are resistance spot welding, laser beam welding and ultrasonic welding. The performance was evaluated in terms of numerous factors such as production cost, degree of automation and weld quality.
Oxy-acetylene welding is the most common method for welding lead. The low melting point of lead means the welder can easily melt the base metal and filler metal with an oxy-acetylene torch to achieve a solid weld. TIG welding is also suitable for welding lead due to the capability of this process to weld at very low amperages.
Lead is a heavy and soft metal used in various industries, including battery manufacturing, radiation shielding, and plumbing. Lead welding is a crucial skill in these industries. Whether you’re a seasoned welder or just starting, understanding the best practices for welding lead is essential.
Tungsten electrodes are commonly used for lead welding due to their high melting point and inert nature. In TIG and resistance welding, the selection of appropriate welding current and voltage settings is critical to achieve the desired weld penetration and quality.
The low melting point of lead means the welder can easily melt the base metal and filler metal with an oxy-acetylene torch to achieve a solid weld. TIG welding is also suitable for welding lead due to the capability of this process to weld at very low amperages. Stick welding is unsuitable for welding lead because the SMAW process is too hot.
The search was then performed using Uppsala University’s Library database and Google scholar which cover a wide range of articles and sources. Three methods for welding batteries were given in the template, being laser beam-, ultrasonic-, and resistance spot welding.

Welding methods for electrical connections in battery systems
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.
