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.
The nominal voltage of a single-cell lead-acid battery is 2V, which can be discharged to 1.5V and charged up to 2.4V. In applications, 6 single-cell lead-acid batteries are often connected in series to form a nominal 12V lead-acid battery. It can also be designed into 24V, 36V, and 48V batteries. What is the structure of lead-acid battery?
For over 20 years, Leko has been designing, installing, and improving lead acid battery assembly line equipment. Leko''s intercell welding machines can process a variety of battery sizes. The Leko BW series of equipment is fully automatic equipment.
The cast-on-strap (COS) process is a widely applied method for grouping plates of the same polarity in each cell of a lead–acid battery. This process brings about the joining or soldering of the grid lugs with the strap, to form a ''COS joint''. The joints provide structural integrity to the cell and act as electrical connections between
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. All three methods are tried and proven to function in the production of battery applications.
1. Introduction Lead-acid batteries are the oldest and the most widely used type of rechargeable batteries available and still in operation in most automobiles and transport vehicles. They are made up of a number of cells in each alternating positive and negative plates (grids) that are immersed in an acidic electrolytic solution.
In addition, it provides the findings of an investigation on the macroscopic and microscopic features of COS joints in commercial lead–acid batteries. Some examples of the most common defects that can affect the performance and life of batteries are presented.
The initial formation charge of a lead-acid battery involves a complex set of chemical reactions to achieve good reproducible results. The process is facilitated by a rectifier, which acts like a pump, removing electrons from the positive plates and pushing them into the negative ones.
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.
Parameter control also allows LBW to adapt to the thickness of the material tabs and can create thin or thick weld nuggets. In battery cell welding it is important to create thin welds due to the relatively thin battery cases and the risk of the weld penetrating the case and thus damaging the core.
