Pay attention to the safety consideration of greenlaser pointer

Laser welding in a workpiece within a vacuum container and in the complex structure of the internal position of the workpiece through the glass; laser beam is easy oriented focus, to achieve the direction of transformation; compared to laser welding and electron beam processing, do not require strict vacuum equipment, operating ; laser welding productivity, stable quality and reliable, economic and social good. Laser welding process characteristics in the production of sensors - laser welding sensor metal casing used to seal one of the most advanced processing methods, mainly based on laser welding has the following characteristics: high aspect ratio. Weld deep and narrow weld bright and beautiful; minimum heat input. The workshop has changed the working time table ofgreen laser pointer.
The high power density, the melting process is very fast, input workpiece low heat, welding speed, thermal deformation, heat affected zone; high compactness. Weld build process, bath, stirring constantly, gas-prone, leading to generate non-stomatal penetration welds. Easy to make the high cooling rate after welding, weld fine, weld strength, toughness and high performance; strong weld. High-temperature heat source and fully absorb the non-metallic components of produce purified role, reducing the impurity content, change the mixture of size and its distribution in the weld pool, electrode or filler wire welding process without the melted zone of contamination is small, the weld strength, toughness, at least equivalent to or even more than the parent metal; precise control. The warehouse ofgreen laser pointerneeds to be periodically cleaned.
Small focused spot weld can be high-precision positioning, beam is easy to transport and control, does not require frequent replacement of the welding torch, nozzle, significantly reduce the downtime of the auxiliary time, high efficiency, light inertia at high speed emergency stop and re-initiation. Welding of complex components using self-control can beam mobile technology; non-contact welding process, the atmospheric environment. Workpiece, because the energy from the laser, no physical contact, so no force is applied to the workpiece. Another magnetic and air had no effect on the laser; average low heat input, high precision, can reduce processing costs, in addition, laser welding operating costs low, which can reduce workpiece cost; easy to automate, the beam intensity and fine positioning could be effectively controlled. The worker should obey the working table of green laser pointer.
Comparison of laser welding with the existing welding methods. Sensor seal welding methods used are: resistance welding, TIG welding, electron beam welding, and other plasma welding. ERW: It is used to weld thin metal electrode contact surface melted by a large current between two electrodes clamping be welder parts, namely, to the implementation of the welding workpiece resistance heating. Easy deformation of the workpiece welding, resistance welding joints on both sides of the laser welding only from the unilateral, resistance welding electrode need regular maintenance to remove the oxide and the metal from the workpiece adhesion, laser welding of thin metal lap joint is not Furthermore, contact with the workpiece, the beam can also enter the region of the conventional welding difficult to weld and welding speed. The customer should pay attention to the safety consideration of green laser pointer.
Argon arc: the use of non-consumable electrode and shielding gas, commonly used to weld thin workpieces, but slower welding speed and heat input is much larger than the laser welding, and easy to produce deformation. Plasma arc welding: similar to TIG welding torch will produce compression arc, in order to improve the arc moderate energy density, it is faster than the argon arc welding speed, deep penetration, but inferior to laser welding. Electron beam welding: it rely on a bunch of accelerated high-energy density electron flow impact the workpiece, in the very dense plot of the workpiece surface, great heat, forming a "hole" effect, thus the implementation of deep penetration welding. The main drawback of the electron beam welding, a high vacuum environment to prevent the electron scattering, complex equipment, the weldment size and shape of the subject to the limitations of the vacuum chamber, requires strict, non-vacuum electron beam welding can also be implemented on the Korea-piece assembly quality, but because of the electronic scattering and bad focus effects. The shoe for the worker in the green laser pointer workshop is specially made.
