What is the principle of laser welding machine
Laser welding machines emit a high-intensity light beam that creates a concentrated heat source, enabling narrow, deep welds and quick welding speeds when focused into a single point.
The 1500w laser welding machine employs high-octane laser pulse to heat one particular area of tiny areas on a work material. The powerful energy of laser radiation diffuses into materials' internal parts through heat conduction, and then the melting material will form a specific molten bath to facilitate the laser welding.
Using a laser beam, a laser welder machine can join together micro-plastics.The laser beam does not scatter like light bulb light, and it is directed in parallel in the same direction. A laser beam has a high energy density as a result of this. So, high energy can be obtained by focusing the parallel light on a single point using a lens. This energy is used in the welding process. What it's all about is the theory that electrons can be excited by taking in energy. It then decays to its ground state and emits a light photon. Stimulated radiation emission increased photon concentration, resulting in a high-energy laser beam.
Features of laser welding
Laser beams can be focused to a very small point compared with arcs used in arc welding. Increasing the energy density using a converging lens makes it possible to use laser welding for localized welding and for joining materials with different melting points. This type of welding is also suitable for detailed welding applications thanks to reduced heat effects, a thin bead, and no generation of processing reaction forces.
■ Characteristic
Because laser beams can be transmitted at atmospheric pressures, laser welding equipment does not require* a vacuum chamber like electron beam welding. The laser beam equipment in laser welding is smaller than the beam equipment in electron beam welding, and automation and precise control using a computer or robot are possible. Fibers and transmission path mirrors also make it possible to perform welding at a distance from the exciter. These advantages make laser welding highly adaptable to various applications, and the ability to utilize remote laser welding, fiber laser welding, and beam scan welding make it possible to meet a variety of welding process needs.
Advantage of laser welding machine
(1) The amount of heat input can be minimized, the metallographic range of the heat affected zone is small, and the deformation due to heat conduction is also the lowest.
(2) The welding process parameters of 32mm plate thickness single pass welding have been qualified, which can reduce the time required for thick plate welding and even eliminate the use of filler metal.
(3) There is no need to use electrodes, no concerns about electrode contamination or damage. And because it is not a contact welding process, the wear and deformation of the machine can be minimized.
(4) The laser beam is easy to focus, align, and guided by the optical instrument. It can be placed at an appropriate distance from the workpiece and can be redirected between the implements or obstacles around the workpiece. Other welding methods are subject to the above space limitations. Can't play.
(5) The workpiece can be placed in a closed space (with vacuum or internal gas environment under control).
(6) The laser beam can be focused on a small area to weld small and closely spaced parts.
(7) The range of weldable materials is large, and various heterogeneous materials can be joined to each other.
(8) It is easy to automate high-speed welding, and it can also be controlled by digital or computer.
(9) When welding thin materials or thin-diameter wires, it is not easy to remelt like arc welding.
(10) It is not affected by the magnetic field (easy for arc welding and electron beam welding) and can accurately align the weldment.
(11) Two metals that can be soldered with different physical properties (such as different resistances).
(12) No vacuum is reauired and X-rav nrotection is not reauired
Disadvantage of laser welding machine :
(1) The position of the weldment must be very precise and must be within the focus of the laser beam.
(2) When the fixture is to be used with a fixture, it must be ensured that the final position of the weldment is aligned with the weld point that the laser beam will impact.
(3) The maximum weldable thickness is limited by the penetration of the workpiece with a thickness of more than 19 mm. The laser welding machine is not suitable for use on the production line.
(4) High reflectivity and high thermal conductivity materials such as aluminum, copper and their alloys, etc., the weldability will be changed by the laser.
(5) When performing medium-to-high-energy laser beam welding, a plasma controller is used to drive out the ionized gas around the molten pool to ensure re-emergence of the weld bead.
(6) The energy conversion efficiency is too low, usually less than 10%.
(7) The weld bead is rapidly solidified and may have pores and embrittlement concems.
(8) The equipment is expensive.

In 2012, after the woodworking machinery and panel furniture production line is used for 4 years, we were deeply troubled by the high price and low quality of the woodworking machinery market. After-sales problems such as precision inaccuracy and flying dust often occur during using, so iGOLDENCNC was created. iGOLDENCNC hired a team of engineers with 20 years of industry experience. Each accessory was tested and screened more than 30 times to produce the first whole-house custom furniture production line. And in the same year, the production line was brought to the CIFM exhibition, and got more attention and praise from professional customers and received dozens of orders.
Our products include: co2 laser engraving machine, co2 laser cutting machine, laser marking machine, fiber laser cutting machine, cnc router machine, metal plasma cutting machine and so on .
iGOLDENCNC was officially established, achieving breakthrough from 0 to 1, and 1 to 100.
Do I need to calibrate the CNC router?
Yes. The CNC router must be calibrated on a regular basis to avoid any potential error in the machining process, in order to meet the customer’s demands as always. In accordance with the manufacturer’s original specifications, CNC machine calibration aims to diagnose and correct errors that may deviate over time.
How to choose between the linear ATC or carousel ATC?
Carousel ATC tool change action more fast. And the linear ATC structure is simple and reliable, but spend more time on tool change.
Do I need to replace the collets of the CNC router?
Yes. The collet is a small part used to physically secure a CNC router cutter to the spindle motor shaft of the CNC router. The collets fall into multiple types and sizes according to the design of CNC router spindle motor shaft and the cutter holder. It is necessary to replace the collets regularly in the daily maintenance of the CNC router. This can ensure better performance, longer service life and better results of the CNC router cutters. If you use your CNC router every day, you may need to replace the collets every three months.
