Spot welding welder PB80

lasersingle-phaseAC

Features

• High depth-to-width ratio with narrow weld width, reduced heat-affected zone, low distortion and high welding speed
• Smooth weld seams requiring no or minimal post-weld finishing
• Porosity-free welds; reduced/optimized base-metal impurity distribution; weld microstructure refined; weld strength and toughness equal to or exceeding base metal
• Precise control with a small focal spot, high-precision positioning and easy integration into automation
• Capable of welding certain dissimilar material combinations
• Supports spot welding, butt welding, lap/seal welding and other joint configurations
• Fine focal spot and strong penetration capacity; flexible installation and remote-control operation

Applications
PB80 is intended for low-energy spot welding, low average power and high-speed spot-welding applications. It is recommended for use with a galvanometer high-speed scanning welding station to exploit high-speed spot-welding capabilities. Typical application sectors include mobile phone housings and shielding, soft PCB soldering in LCDs, welding of optical and microelectronic components, and medical precision parts.

Brief Description
The laser power supply drives a pulsed xenon lamp to generate optical pulses that excite the Nd3+:YAG laser crystal via a condenser cavity. After resonation in the laser cavity, the system emits pulsed laser radiation at 1064 nm. Under PLC or industrial PC control, the pulse laser beam is expanded, reflected or transmitted via fiber, then focused onto the workpiece for welding. Pulse frequency, pulse width, waveform, and table motion can be controlled to match process requirements.
