Laser welding equipment What is the difference between cold working and hot working?
Today's Laser technology It has become more and more sophisticated, especially in laser marking, whether metal or non-metal work can be marked. Laser marking is especially suitable for precision machining. The graphics and texts of laser symbols are delicate and beautiful, will not be erased, and will not fade or benefit due to a long time. It can not only improve the level of products, but also play the role of anti collusion and anti-counterfeiting.
In order to meet the needs of various work, the laser marking machine has developed the required series. For different series and different data for different work, the integrated cabinet is generally selected for laser marking. This planning makes the laser marking machine small and does not occupy space.
Laser welding equipment
Laser marking machines are generally divided into two types: one is cold processing, the other is hot processing. These two processing technologies are mainly aimed at different data. Generally speaking, thermal processing is for metal work, while processing is for plastic laser welding equipment that cannot be heated.
Difference between laser marking cold working and hot working
Laser marking cold processing: green light marking machine and ultraviolet laser marking machine generally use cold processing. Cold working is a new and high technology developed in recent years. It mainly shines on the workpiece surface through the laser beam with high energy density, and the data surface absorbs laser energy, causing non thermal harm to the data. Due to cold working, the laser welding equipment will not burn out and damage the black edge and deformation of the workpiece.
Laser marking thermal processing: select the high-energy laser beam for thermal processing to irradiate the surface of the workpiece, produce thermal response in the irradiation area, raise its temperature to, and reach the phenomenon of incineration, dissolution and evaporation, and then reach our predetermined policy role. This laser beam is mainly used in optical fiber laser marking machine, CO2 laser marking machine and semiconductor laser marking machine.
Whether cold processing or hot processing is selected, the contribution of laser marking machine to industrial marking cannot be replaced. The laser marking machine has the advantages of high quality, durability, inorganic pressure processing, no consumables, no pollution, no noise and assembly line production, which makes it an indispensable member in industrial processing. Especially in today's electronic and electrical work, the traditional marking method is simple to fade and erase, which may lead to not knowing what type of product this product is. If the retest needs a lot of manpower and material resources, it is doomed to use laser marking machine to replace the traditional marking method.
