Laser welding process parameters, pulse laser welding has four main parameters: pulse energy, pulse width, power density and defocusing; continuous green laser pen welding parameters are: high power laser pointer power, welding speed, spot diameter, defocus, type of protective gas and flow; parameters of double beam laser welding include: beam arrangement, spacing, angle of two beams, focus position, energy ratio of two beams, etc. Laser hybrid welding types include: laser-arc hybrid welding, laser-high frequency welding, laser-pressure welding, laser-brazing, etc. Among them, laser-arc welding is the most common, such as laser-argon arc welding (TIG), laser-gas welding (MIG), etc. According to the relative position of laser and arc: coaxial composite, cross composite, eccentric composite.
Really like the 200mw green laser pointer
My family loves this pointer Green Laser Pointer 200mW! It's so small, but it's fully functional, and he brings the scene on the field! It doesn't include battery requirements, so make sure you have an 18650 battery so you can try it out when it happens! It has different modes and levels of light, including high power, high and low. Another book focuses on blue lasers on reflective surfaces. When using it, you can instinctively avoid pointing directly at yourself or others, but you may touch a glossy surface and go unnoticed, while others can cause problems with your eyes to send enough energy. Also, even with limited exposure, it cannot be "blind", it may kill every little piece of the retina. Your brain makes mistakes to correct, so you don't notice, but repeated damage has a cumulative effect. be careful.
When the laser is applied to the material with pulse times on the order of picoseconds and femtoseconds, the processing effect changes dramatically. Femtosecond lasers can be focused on regions of space smaller than the diameter of a human hair, making electromagnetic fields several times stronger than the force of atomic nuclei on their surrounding electrons, enabling many other methods that do not exist on Earth. Extreme physical conditions are also not available. With the sharp rise of the pulse energy, the laser pulse of high power density can easily strip the outer electrons, so that the electrons are separated from the atoms to form a plasma. Due to the interaction time between the green laser pointer and the extremely short material, the plasma cannot transfer energy to the surrounding material and has been ablated from the surface of the material without thermally affecting the surrounding material. Therefore, ultrafast laser processing is also referred to as "cold processing".
