Introduction

The laser welding system is an important aspect of laser process technology application. The laser welding process is thermal conduction, i.e. the laser radiation heats the surface of work piece, and the surface heat diffuses to the interior through thermal conduction and melts the work piece by controlling the width, energy, peak power and repeating frequency of laser pulse to form specific molten pool. Because of its unique advantage, it is widely used in the process of gold and silver jewelry and welding of Engg parts. These welding machines can be used Manually with Hand Held Welding Head as well as can attached with Automation Systems or Robotics as per applications.

Fiber Laser Source based laser welding machines are ideal for continuous welding, seam welding & drilling in the long pulse operation mode. These air-cooled, compact units are substantially more cost-effective than conventional Nd:YAG lasers due to >30% wall -plug efficiencies and maintenance-free operation. The fiber lasers are available for requalifying existing lamp-pumped processes at the application facilities and applications labs.
