Battery Manufacturing: Lead welding is fundamental in battery manufacturing processes. It is used to join lead plates to connectors, ensuring a secure and efficient electrical connection. This is essential for the proper functioning of lead-acid batteries, which power a wide range of devices and vehicles.
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.

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.
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 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.
