Laser sensor for weld metal seal is one of the most advanced processing methods, mainly based on laser Welding Electrodes has the following characteristics:
(1) high aspect ratio. Deep and narrow weld, weld bright and beautiful.
(2) The minimum heat input. As the power density, melting fast, low heat input workpiece, welding speed, heat distortion, heat affected zone.
(3) high compactness. Generated during welding, bath, stirring constantly, gas-prone, leading to generate non-porous weld penetration. High cooling rate after welding to weld and easy miniaturization, weld strength, high toughness and overall performance.
(4) strong weld. High-temperature heat source and the absorption of non-metallic components have purified the full effect, reducing the impurities to change the size and its inclusion in the distribution in the bath, the electrode or the welding process without filler wire, melting the contaminated area is small, the weld strength, toughness at least equal or even exceed the parent metal.
(5) precise control. Because the focal spot is small, the weld can be high-precision positioning, the beam is easy to transport and control, does not require frequent replacement torch, nozzle, significantly reducing downtime auxiliary time, high efficiency, light no inertia, but also in high speed emergency stop and re-initiation. Mobile technology with controlled beam welding can be complex components.
(6) non-contact, atmospheric welding process. Because the energy from the laser, the workpiece is no physical contact, so there is no force applied to the workpiece. The other magnetic and air have no effect on the laser.
(7) The average heat input low, high precision, can reduce the cost of reprocessing, the other, less expensive Copper Welding Electrode operation, which can reduce parts costs.
(8) easy to automate, and fine positioning of the beam intensity can be effectively controlled.
