Chapter 1 Introduction: The Core Technology of the Precision Welding Era
1.1 What is Pulsed Laser Welding
Pulsed laser welding is an advanced manufacturing process that utilizes short-pulse (nanosecond to millisecond) laser energy to join materials together. Unlike continuous-wave lasers, pulsed lasers apply intermittent high-energy-density beams to the workpiece, achieving material melting and bonding through heat conduction or keyhole welding mechanisms.
The core advantage of this technology lies in its extremely high energy density and precise control capabilities. By adjusting pulse width, peak power, repetition frequency, and waveform (square wave, spike wave, double-peak wave, etc.), heat input can be precisely controlled, achieving minimal heat-affected zones, aesthetically pleasing weld seams, and low deformation.
1.2 Technical Principles and Core Components
A pulsed laser welding machine primarily consists of the following core components:
Laser Generator: Produces pulsed laser light at specific wavelengths. Common types include YAG (yttrium aluminum garnet, wavelength 1064nm) lasers and fiber lasers.
Beam Delivery System: Guides the laser beam to the workpiece, achievable through mirrors or fiber optic transmission.
Control System: Manages laser parameters, worktable motion, and auxiliary equipment to enable automated welding, typically controlled by PLC or industrial PC.
Focusing and Observation System: Precisely focuses the beam spot and provides real-time monitoring of the welding process.
During the welding process, the laser power supply excites pulsed xenon lamps or diodes, which pump the laser crystal to generate laser light at specific wavelengths. After amplification in the resonant cavity, the beam undergoes beam expansion and focusing, ultimately acting on the workpiece surface to form a molten pool.
