Yag Laser Welder Series

Model introduction

    This welder is specially developed for laser welding of jewelry by Chinasky and mainly used in perforating and spot welding of gold and silver jewelry. The laser spot welding is an important aspect of laser process technology application. The spot 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 mini and small parts.

Model Features

   ◎The energy, pulse width, frequency and light spot size can be adjusted in a large range to realize different welding effects. The parameters are adjusted by the lever in the seal cavity, which is Simple and highly efficient.

   ◎Ceramic converging cavity is imported from the Britain. It is corrosion resistant and high temperature resistant, and has 8-10 years service life.The life of xenon lamp is more than 8 million times.

   ◎Use the most advanced light shielding system to eliminate the irritation to eyes by light during working.

   ◎Able to work for 24 hours continuously; stable performance.

   ◎Human-based design accords with ergonomics, avoiding fatigue after long time working.

The advantage

   ◎High speed, high efficiency, deep, small deformation, small heat effect area, high welding quality, pollution free welding spot, environmental friendly.

Application areas

Widely used in aviation, aerospace, sports products, jewelry, golf head, medical instrument, titanium alloy denture, instrument, electronics,machinery, automobiles, etc, especially for the perforating of gold and silver jewelry, spot welding, repairing, inlay and welding of claw.
