The handheld laser welding machine is a simple and easy-to-operate portable device. It is also a new type of precision welding equipment, which is suitable for various environments including outdoor welding. The hand-held laser welding machine replaces the traditional fixed welding torch optical path, which is more flexible and convenient, realizes the outdoor long-distance welding of the laser, and overcomes the limitation of the working space; The external handheld welding head is equipped with 5 meters of imported optical fiber, which is flexible and convenient for outdoor welding. The workpiece can be welded at any angle, the dual optical paths are intelligently switched, and the time-sharing energy is evenly distributed. It can also be easily welded for polygonal materials. It is suitable for all kinds of messy welding and spot welding of equipment. So how thick can the hand-held laser welding machine weld?
The depth of laser welding is related to the properties of the material, and of course the thickness of the material. It is impossible to use the same parameters for welding carbon steel and titanium.
Different metal materials have different melting points:
The parameter settings of different types of materials are more complicated, and the thermal properties of welding materials vary with temperature; the difference in laser absorptivity of different types of metals and their characteristics with temperature changes; the formation and evolution mechanism of molten pool; Microstructure evolution; formation of laser welding joint defects, welding residual stress and deformation, etc. However, the key problems can be attributed to the influence of material property differences on the microstructure and macroscopic properties of the weld; the formation and evolution mechanism of the weld pool, and the formation of welding defects and residual stress during the solidification of the weld pool.
Does the welding of different powers of the laser welding machine have anything to do with the thickness of the plate?
Handheld laser welding machine is currently a widely used model on the market. Due to its cost-effective model and longevity application, it is generally recognized by the public. Therefore, the issue of price has always been an important point of attention. Handheld laser welding machines are currently sold at this stage. With the price of cabbage, fool-like operation, it has become a general-purpose device.
The depth of laser welding is related to the properties of the material, including the thickness of the material, of course. It is impossible to use the same parameters for welding carbon steel and titanium. The higher the laser power, the thicker the welding thickness.
The welding material is different, and the effect of welding thickness is different. For example, 1000w for welding stainless steel can be welded to 3 mm, and 1500w for welding copper iron may only reach 2 mm.
For example, welding: 2mm thick stainless steel plate requires penetration, and the thinner the weld, the better. It is recommended to use 1000W fiber laser welding, the speed can reach more than 1 m/min, 500W can also be used but the speed is slower.
For example, welding: 500W laser welding is used to weld a stainless steel plate with a thickness of 3mm. A single-sided welding can penetrate a material with a thickness of 1.5mm. If both sides are welded, each 1.5mm is used, and the material with a thickness of 3mm is fully welded;
For example, welding: 1000 watt welding of 10mm stainless steel plate can also be welded, and the molten pool can be 3mm on one side. The tensile force requirements of some production ports are not high, but they can also meet the requirements. If the speed is slowed down, the welding may be deep enough 5mm.
People generally think that the higher the power of the laser welding machine, the better, because the higher power is more expensive than the lower power. The welding effect of fiber laser welding machine is not only related to its power, but also closely related to its accessories, production quality of the whole machine, software control system, optical system and many other factors.
