Laser-Hybrid Welding: Key Technology for Automotive Camera Housing ManufacturingAmid the wave of automotive intelligence, automotive cameras serve as core sensors for autonomous driving and active-safety systems. Their manufacturing precision and reliability directly determine vehicle-safety perform

Laser welding is a branch of laser-based metalworking technology, widely applied across numerous industrial sectors including automotive, precision equipment, electrical appliances, aerospace and medical devices. Among its many applications, this article focuses on laser welding for sheet-metal proc

No universal laser cutting head exists. Processing scenarios impose vastly different requirements on optical path structure, nozzle layout, follow-up precision and protective performance. For most manufacturers, issues including unstable cutting, scrapped special-shaped workpieces, uneven bevels, piercing deformation during pipe cutting and directional laser reflection rarely stem from insufficient laser power. Instead, they are mainly caused by mismatched cutting heads for specific processing applications.

MOPA (Master Oscillator Power Amplifier) pulsed fiber lasers feature independently adjustable pulse width and repetition frequency. With this unique advantage, they have become essential processing tools in the fields of electronic information (e.g., metal marking and welding) and new energy (e.g., photovoltaic cell scribing and lithium battery pole piece cutting). However, service life is the top concern for users during model selection and daily operation of MOPA pulsed fiber lasers. Based on practical engineering experience, this paper analyzes the lifetime determination mechanism of MOPA pulsed fiber lasers and summarizes product life extension strategies from three dimensions: design, production and application.
