Laser welding is a method of joining materials using the heat generated by lasers. Laser welding can be used to join metals, ceramics, glass and other materials. The basic concept of a laser welding machine is similar to that of conventional electric arc welding, in which a filler metal is melted as it is drawn into the joint by capillary action. The difference between laser and electric arc welding is that in laser-beam welding, the filler metal does not need to be heated before it is deposited, because the beam melts it on contact.
Laser beams can be focused so tightly that they will melt materials on contact. A laser beam creates intense heat through selective absorption of light at a specific wavelength by an absorbing material. This process can be used for high-speed material processing or for cutting or drilling holes in metal or other types of materials.
Laser welding has many advantages over other welding processes:
• It can be used on almost all metals and alloys, including stainless steel and titanium alloys (which are difficult to weld with conventional methods).
• It can be used with any shape of part because it works on only a very small area at a time (less than 1mm).
• It can be used with thin sheets of material (down to 0.1mm thick) which would otherwise be impossible using conventional processes such as gas welding or flame spraying.
Main Features of Laser Welding Machines
The main components of a laser welding machine are as follows:
Laser beam source
The laser beam source generates high-quality beams that are focused on a particular area. The laser beam source is usually made up of several parts such as mirrors, lenses and diffraction gratings. The quality of the laser beam depends on the quality of these components.
Laser power supply unit
The laser power supply unit provides electrical energy to the entire system and contains an inverter that converts AC power into DC power. The inverter unit also converts voltage levels so that they can be compatible with other components in the system. A transformer may be included in this unit so that electricity can be supplied from different sources such as batteries or generators.
Control panel
Controlling all operations within a laser welding machine is done via a control panel which consists of buttons, switches and meters for displaying data readings from various sensors within the system. These sensors monitor temperature levels in different parts of the laser welding machine such as lens housings and mirrors, air flow rates through ventilation systems and much more!
Final Words
Laser welding is a great process for joining materials together, whether it be metals, plastics or any other type of material. It has many advantages over other methods and can be used in a wide range of applications. If you need to weld something, then a laser welding machine is the way to go!
