Stainless steel laser welding machine is a new welding method, which is widely used in precision processing industries such as automobile industry, metal processing industry, ship and aircraft manufacturing, Furniture and kitchenware processing, electronic products processing, metal parts maintenance, etc. It is mainly aimed at the welding of thin-walled materials and precision parts. It can realize spot welding, butt welding, overlap welding and seal welding. 1500w laser welder for titanium alloy, galvanized sheet, aluminum material and copper material can accurately weld
This process overturns the working mode of the traditional hand laser welder. It has the advantages of simple operation, beautiful welding seam, fast welding speed, and no consumables. It can be perfect for welding thin stainless steel plates, iron plates, galvanized plates and other metal materials. It replaces traditional argon arc welding of stainless steel plate, iron plate, aluminum plate and other metal materials welding.
Optical fiber continuous automatic laser welding machine in a given optical system, the laser spot size of higher output beam quality is smaller, so the processing efficiency can be improved. For most materials, through laser wire filling, laser-MIG hybrid welding, dual-spot laser welding and other processes, the forming effect of aluminum alloy welding can be significantly improved. The rough metal surface has a high degree of sandblasting, light reflectivity and a clean surface. , Which indicates that the laser energy input is less and the welding quality is improved.
The welding of steel and aluminum alloy itself can be very problematic. The typical problem is that the strength of the welded joint drops sharply. The more serious problem is that there is no tin connection at all. The melting temperature of steel is generally about 1600°C, while the melting temperature of aluminum alloy is about 600°C.
Therefore, the welding heat source is very critical. In fusion welding, the butt joint of steel and aluminum is not easy to melt at the same time. The coefficient of thermal expansion and thermal conductivity of steel and aluminum are very different. Aluminum is more likely to cause greater thermal deformation and thermal stress, and it is also easier to conduct heat.
The melting of aluminum alloy requires a higher power density of the heat source. Another serious problem in the welding of steel and aluminum is the production of iron-aluminum intermetallic compounds, which are brittle phases, which will severely reduce the strength of the welded joint in the weld.
(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 required and X-ray protection is not required.
(13) If the hole is welded, the width of the weld bead can reach 10:1.(14) The switching device can transmit the laser beam to a plurality of workstations.
