Manual plasma cutting method using heat current cutting, welding Huashi professional design painstakingly created, the cutting edge produce heat-affected zone, which gives stainless steel bright white "pollution" on a circle slightly color gradient. At the same time, through the regulation of welding specifications, cutting instant strong airflow gun discharged in the molten steel cut at the cutting edge of "blow" from the texture circle randomly formed after the completion of cutting the metal to cool and solidify as a very fine cut marks, Huashi welding, the intermediate flat polished stainless steel plate in contrast texture. This formation of random effects with a certain chance, but is the phenomenon in certain welding specifications inevitably produce. For there are two main laser welding, namely CO2 laser and Nd: YAG laser. CO2 lasers and Nd: YAG laser is invisible infrared light. Nd: YAG laser beam is mainly generated near-infrared light with a wavelength of 1. 06 Lm, thermal conductors such wavelength of the light absorption rate is high, Huashi welding application of the industry, for the most metal, its reflectivity from 20% to 30%. Just use a standard light microscope can make the near-infrared beam is focused to a diameter of 0. 25 mm. CO2 laser beam is far-infrared light, a wavelength of 10. 6Lm, most metals such light reflectance of 80% to 90%, need special microscope to focus the beam to a diameter of 0. 75 - 0. 1mm ??? Nd: YAG laser power generally can reach about 4 000 ~ 6 000W, maximum power is now reached 10 000W. The CO2 laser power but it can easily reach 20 000W or greater.
