Laser welding machine has become a new industrial technology in the process of industrial welding because of its advantages of fast welding speed, high precision, high efficiency and smooth and beautiful weld. Laser welding machine has been widely used, but many people do not know what materials laser welding machine can weld.

1.模具钢

1. Die steel

激光焊机可用于各种模具钢的焊接，焊接效果良好。

Laser welding machine can be used for welding various die steels with good welding effect.

2.碳钢

2. Carbon steel

钢是用激光焊接机焊接的，焊接质量取决于杂质含量。为了获得良好的焊接质量，需要在碳含量超过0.25%时进行预热。当不同含碳量的钢焊接在一起时，焊枪可以稍微倾斜到低碳材料的一侧，以保证接头的质量。由于激光焊机的加热速度和冷却速度都很快，所以在焊接碳素钢时。随着碳含量的增加，焊接裂纹和缺口的敏性也随之增加。中、高碳钢和普通合金钢可以用激光焊接，但需要预热和焊后处理，以解决应力，避免裂纹。

Steel is welded by laser welding machine, and the welding quality depends on the impurity content. In order to obtain good welding quality, preheating is required when the carbon content exceeds 0.25%. When steels with different carbon contents are welded together, the welding gun can be slightly tilted to the side of low-carbon material to ensure the quality of the joint. Because the heating speed and cooling speed of laser welding machine are very fast, when welding carbon steel. With the increase of carbon content, the sensitivity of welding crack and notch also increases. Medium and high carbon steel and ordinary alloy steel can be welded by laser, but preheating and post weld treatment are required to solve the stress and avoid cracks.

3.合金钢

3. Alloy steel

只要选择合适的焊接参数，低合金钢和高强度钢的激光焊接就能获得具有母材力学性能的接头。

As long as appropriate welding parameters are selected, the joints with mechanical properties of base metal can be obtained by laser welding of low alloy steel and high strength steel.

4.不锈钢

4. Stainless steel

一般来说，不锈钢焊接比常规焊接更容易获得高质量的焊接接头。由于激光焊接的高焊接速度和热影响区很小，减轻了过热和线膨胀系数对不锈钢焊接的不利影响，不存在气孔、夹杂物等缺陷，与碳钢相比，不锈钢具有低的导热性、高的吸收和熔化效率，更容易获得深熔深焊接。通过低功率激光焊接机厂家，可以获得外观良好、焊缝光滑、美观的接头。

Generally speaking, stainless steel welding is easier to obtain high-quality welded joints than conventional welding. Due to the high welding speed and small heat affected zone of laser welding, the adverse effects of overheating and linear expansion coefficient on stainless steel welding are reduced, and there are no defects such as pores and inclusions. Compared with carbon steel, stainless steel has low thermal conductivity, high absorption and melting efficiency, and it is easier to obtain deep penetration welding. Through the manufacturer of low-power laser welding machine, the joint with good appearance, smooth weld and beautiful appearance can be obtained.

5.铜和铜合金

5. Copper and copper alloys

铜和铜合金焊接容易引起熔透问题，应采用集中大功率热源和预热措施；当工件厚度较薄或结构刚度较小时，没有防止变形的措施，焊接后容易产生较大变形，但焊接接头受到较大的刚性约束时，容易产生焊接应力；铜和铜合金焊接时也容易出现热裂纹。气孔是铜和铜合金焊接中常见的缺陷之一。

The welding of copper and copper alloy is easy to cause penetration problems, so centralized high-power heat source and preheating measures should be adopted; When the thickness of the workpiece is thin or the structural stiffness is small, and there are no measures to prevent deformation, it is easy to produce large deformation after welding, but when the welded joint is subject to large rigid constraints, it is easy to produce welding stress; Copper and copper alloys are also prone to thermal cracks during welding. Porosity is one of the common defects in copper and copper alloy welding.

6.铝和铝合金

6. Aluminum and aluminum alloys

铝和铝合金是一种高度反射材料。随着温度的升高，氢在铝中的溶解度急剧增加，溶解氢成为焊缝的缺陷源，焊缝中有许多气孔，但深熔焊根部可能会出现空洞，焊缝成形不良。

Aluminum and aluminum alloys are highly reflective materials. With the increase of temperature, the solubility of hydrogen in aluminum increases sharply. Dissolved hydrogen becomes the defect source of the weld. There are many pores in the weld, but there may be cavities at the root of deep penetration welding and poor weld formation.

激光焊接机材料远远超过这些材料。激光焊接厂家可以在各种不同的金属之间进行。结果表明，在一定条件下，激光焊接厂家可以在铜-镍、镍-钛、铜-钛、钛-钼、黄铜、低碳钢-铜和其他不同金属之间进行。

Laser welding machine materials far exceed these materials. Laser welding can be carried out between different metals by manufacturers. The results show that under certain conditions, laser welding manufacturers can carry out between copper nickel, nickel titanium, copper titanium, titanium molybdenum, brass, low carbon steel copper and other different metals.
