Five necessary conditions for the work of automatic welding equipment 1. Stimulated emission: the first condition commonly used welding equipment, but also a necessary condition, but not a sufficient condition. 2. Working substance must have metastable level If these children one by one by a laser welding device is emitted, can not create a strong energy. (Spontaneous emission) In general, after the electrons are excited to a high energy level, the energy level in residence time is short. And some electronic material in the second level a longer time, second only to ground level. This level is called the metastable level. 3. inversion external excitation photon energy photons generated by stimulated emission wheel welding equipment, but it may be absorbed by a low energy level. In the laser working medium, stimulated emission and stimulated absorption Both processes exist. At room temperature, absorb more than launch. Select the appropriate material to the high (ADB) more than the energy level of electrons on electronic low energy level, and that the formation of inversion, so that stimulated emission than absorption. The resonant cavity laser photons produced in the beginning of spontaneous radiation, the frequency and direction disorganized. For frequency simple, centralized direction, there must be a cavity 5. The gain is greater than the loss laser material and the cavity will cause the loss of photons. Only photons in a cavity oscillation number of photons generated far more than the loss out of the photon, in order to have amplification. Aluminum and aluminum alloy welding what to do preparatory work before 1, to clean up before welding; aluminum and aluminum alloy welding before welding should be strictly removed oxide film and the oil of the workpiece and wire weld surface; removal method according to the following two methods: 1 ) high chemical cleaning chemical cleaning efficiency, stable quality, clean up the wire and is not suitable for the size, mass-produced parts. Available in two French immersion method and scrubbing. Available surface organic solvent acetone, gasoline and kerosene to oil, with a 5% ~ 10% NaOH solution Caustic 40 ℃ ~ 70 ℃ of 3min ~ 7min (aluminum take longer but not more than 20min) holiday welding equipment, mobile water rinse followed by room temperature to 60 ℃ of 30% HNO3 acid solution 1min ~ 3min, mobile wash, air dry or low temperature drying. 2) mechanical cleaning: the workpiece size is larger, longer production cycle, multi-layer welding or chemical cleaning after contamination, often by mechanical cleaning. With acetone, gasoline and other organic solvents to wipe the surface of the oil, followed directly with a diameter of 0.15mm ~ 0.2mm copper wire brush or stainless steel wire brush, brush the exposed metallic luster so far. Generally should not use the wheel or ordinary sandpaper, in order to avoid sand left on the metal surface, into the bath defects such as slag generated during welding. There is also available scraper, rasp and other clean-up surface to be welded. Note: The storage time is too long to clean up (if more than 24h) should be re-processed.
