Different welding methods are used to make all the necessary tab-to-terminal connections (foil-to-tab, tab-to-busbar, etc.) These methods include ultrasonic bonding, laser welding, resistance welding, and micro TIG welding. Whether one method is better suited than another depends on the requirements, such as the combination of materials and the tab thickness.
Structural batteries are changing the way electric cars are assembled. Structural adhesives are replacing screws and welds to “glue” components together using a process called adhesive bonding. This process requires additional surface preparation and creates new challenges for automakers and battery makers
Pouch cells are the first choice for many manufacturers because of their high energy density, great power performances and other design advantages. While they are widely used in electric vehicles, automotive OEMs have strong opinions about whether they should be used.
Ultrasonic bonding, or ultrasonic welding, is an industrial welding process that uses ultrasonic vibrations to join plastics, metals, or dissimilar materials together. During welding, the joined materials are typically held together by a fixture and a sonotrode.
People from all backgrounds met at this event: engineers, innovators, thought leaders, leading suppliers, industry executives and decision makers were all there to shape the future of electric vehicles and batteries.
Each marking technology has its benefits and drawbacks. Between dot peening, inkjet printing, laser marking, and printed labels, the right solution is not always obvious. The key to choosing the best technology is to understand your marking requirements.
Manufacturers who need permanent markings for traceability typically have two options: dot peen marking or laser marking. Between these two technologies, the choice is not always easy.
Different types of lasers are needed for different applications. Based on their gain medium, lasers are classified into five main types: gas lasers, solid-state lasers, fiber lasers, liquid lasers (dye lasers), and semiconductor lasers (laser diodes).
All over the world, laser products are identified with warning labels like the ones above. But what does a Class 1 label mean? And who decides which labels to apply?
Every capital investment is a huge decision, and buying a laser marking machine is no exception. Despite the high initial cost, the investment is worth every penny for a growing number of manufacturers.
For a lot of people, lasers are small boxes that shoot red dots, which drive cats crazy. But in fact, laser systems are used in many manufacturing processes.
Laser engraving is a process that vaporizes materials into fumes to engrave permanent, deep marks. The laser beam acts as a chisel, incising marks by removing layers from the surface of the material. The laser hits localized areas with massive levels of energy to generate the high heat required for vaporization.
