The traditional welding machine process in the case of welding is the use of high temperature characteristics, and then because the temperature and time to control the poor effect of welding, but since the laser welding machine came out, its actual welding effect suffered by our love, and there are more and more companies use laser welding machine to complete production and manufacturing. Laser welding function welding which raw materials?
Laser welding function Which raw materials to weld, alloy structural steel laser welding of high strength steel, as long as the selected welding main parameters are moderate, you can obtain a very physical properties of the original material connection head. In general, the welding of stainless steel plates is easier to obtain high-quality joints than traditional welding.
Because the laser welding high welding rate and the thermal hazard area is not large, it alleviates the overtemperature problem and the negative impact of the large thermal expansion coefficient when welding the stainless steel plate, and the weld has no porosity, impurity and other shortcomings. Compared with carbon steel, stainless steel is very easy to obtain deep weld because of its low thermal conductivity index, high kinetic energy digestibility and melting efficiency. Thin metal plates can be welded by laser welding with low output power, and the joints with good shape and smooth weld can be obtained.
Aluminum and aluminum alloy profiles are highly reflective raw materials, aluminum and aluminum alloy welding, with the rise of temperature, hydrogen solubility in aluminum greatly expanded, melted hydrogen into the weld defect source, there are holes in the weld, and deep arc welding is likely to produce cracks at the root, weld formation is weak.
Carbon steel is welded with laser welding machine, the actual effect is good, and its welding quality is good or bad in the residue content. In order to obtain better welding quality, the carbon content above 0.25% must be heated. When steels with different carbon content are welded to each other, the torch can be slightly tilted to the side of the low-carbon material to ensure the quality of the joint head. Because the heating rate and cooling rate of the laser welding machine are particularly fast, when welding carbon steel.
With the increase of carbon content, the sensitivity of welding cracks and gaps will also increase. Medium and medium carbon steel and general carbon steel can carry out better laser welding, but it is necessary to carry out heating and post-welding processing to remove ground stress and prevent cracks.
