Laser Welding Provides Unique Benefits for EV Manufacturers
High Quality, Low Resistance Connections
Laser welding easily overcomes the common challenges of welding copper, aluminum, nickel-coated steels, and steel alloys to create high-quality joints that optimize electrical properties with minimal heat input.
High Yield & Throughput
Laser welding is faster than other welding methods and is easily integrated with automation and process control like real-time weld quality assurance that measures critical weld parameters without increasing cycle times.
Tooling Flexibility
Laser welding only requires single-sided access, greatly reducing manufacturing complexity and tooling requirements when welding electric components like inverters, busbars, and power distribution units.
Five Key Laser Welding Advantages
for Electronic Components & Modules
Dissimilar Material Welding Made Easy
Single-mode lasers use high power density to easily join dissimilar materials frequently used in contact-to-busbar connections with minimal heat input, simultaneously protecting nearby heat-sensitive components.
Spatter & Porosity Virtually Eliminated
Weld spatter and porosity, which increase the risk of short circuits in electronic components, are virtually eliminated by dual-beam technology that minimizes weld defects without reducing welding speed.
Extended Process Window
Adjustable Mode Beam (AMB) dual-beam technology is more configurable than alternative dual-beam technologies, ensuring high-quality contact-to-busbar joints across a wider range of part variances.
High-Speed, Cost-Effective Welding
Air-cooled Quasi-Continuous Wave (QCW) lasers use burst of high peak power to rapidly achieve the required weld depth in thicker busbars at lower average powers, reducing overhead costs without sacrificing welding speed.
Real-Time Weld Measurement
IPG real-time weld measurement provides in-process contact-to-busbar weld data that enables the consistent creation of low resistance joints by guarding against process drift.
