Industrial laser welding of copper is in growing demand. One reason is the electrification of the automotive industry, where various electrical components are made of copper to improve electrical and thermal conductivity.
Lasers and robotics are both used by manufacturers for their speed and precision. It’s natural that these two technologies frequently work hand in hand in production lines to perform laser welding.
We’ve reached a time where laser welding is not only viable for high-volume production lines, but also for all types of manufacturers. With laser welding being so accessible, now is a good time to explore this proven process that promises precision, speed, and cost effectiveness.
To apply adhesives, manufacturers use a method called adhesive bonding. Due to its many benefits, it is widely used to replace welds and mechanical fasteners.
There are countless ways to blast a surface due to the variety of abrasive materials. In today’s industrial environments, grit blasting is often chosen because it is low cost and effective when cleaning several types of large surfaces, including metals, plastics, and ceramics.
Bonds are an important part of a wide range of products, from EV batteries to aerospace components. To ensure the products’ safety and long-term quality, these bonds must be reliable and durable. Especially when they are exposed to stresses, loads, and high levels of energy. To achieve this, strong bonds are needed.
While fiber lasers, CO2 lasers, and diode lasers can all be used to engrave metal, the kind of laser engraver you need depends on how you want to use it. If you run a production line, you’ll need a fiber laser. If you have small business or just want to do DIY projects as a beginner, a CO2 laser or a diode laser may be sufficient.
Oxide removal is essential to prevent weld contamination, maximize the bond strength of coatings and adhesives, and increase part durability. Laser cleaning, mechanical abrasives, pickling chemicals and other chemicals have all proven effective in cleaning oxidized aluminum.
While laser welding is known for its ability to produce high-quality welds at high speeds, integrating this technology into EV battery production lines presents unique challenges.
EV manufacturers need to work with laser and automation experts that know how to address these challenges if they want to achieve a high yield and produce at a high rate.
Fiber laser cleaners are becoming increasingly popular to clean metal surfaces due to their many advantages over traditional cleaning methods like sandblasting and chemical cleaning.
Thermally conductive adhesives such as tapes, films, and glues are used to bond heat-generating components to heat sinks. Thermal adhesives not only conduct heat, but they can also provide structural integrity, electrical insulation, or electrical conductivity.
In EV battery manufacturing, adhesives are increasingly used to bond components. They are replacing mechanical fasteners as well various joining technologies. Unlike screws, bolts, and welding, structural adhesives provide a range of benefits beyond the bond.
