Inquire

  Laser welding is to use high-energy laser pulse to heat the material in a small area. The energy radiated by laser is diffused through the heat transfer to guide the internal diffusion of the material, and the material is melted to form a specific molten pool to achieve the purpose of welding. With the development of technology, laser welding machine can weld many kinds of metals, and the welding effect is very satisfactory.

  Laser welding can be used in many dissimilar metals, such as copper nickel, nickel titanium, copper titanium, titanium molybdenum, brass copper, low carbon steel copper and so on.

  The welding spot of laser welding machine is small, the welding seam is narrow, neat and beautiful, and there is no need to deal with or simply deal with the process after welding. In order to obtain satisfactory welding quality, preheating is needed when the carbon content is more than 0.25%. When the steels with different carbon content are welded with each other, the welding torch can be slightly inclined to the side of the low carbon material to ensure the joint quality. The laser welding machine has uniform weld structure, few pores and defects, which can reduce and optimize the parent material miscellaneous. The mechanical strength of the weld is often higher than that of the parent material.

  The laser welding effect of 4mm carbon steel stack welding carbon steel is good, and its welding quality depends on the impurity content. Medium and high carbon steel and common alloy steel can be laser welded well, but preheating and post welding treatment are needed to eliminate stress and avoid crack formation. Like other welding processes, sulfur and phosphorus are the sensitive factors to produce welding cracks. How much is the price of a hand-held laser welder?

  When the steels with different carbon content are welded with each other, the welding torch can be slightly inclined to the side of the low carbon material to ensure the joint quality. Low carbon rimmed steel is not suitable for laser welding because of its high content of sulfur and phosphorus. Low carbon killed steel has a good welding effect because of its low content of impurities.
