I mean, which is more effective for flat panel solar energy, ultrasonic welding or laser welding? Domestic ultrasonic welding equipment has been better manufacturers?
Ultrasonic contact welding, laser welding is a non-contact, no doubt the laser efficiency is high, because of the material itself by injecting contact type of thermal vibration complete heat, while the laser is injected into the energy directly, the energy injection ratio is not a grade, so only the laser efficiency is high, but the disadvantage is the limited laser in the infrared spectral characteristics, which is the limit of material
Laser welder is more efficient, of course
