焊缝展示

铝和铝合金都具有非常优良的性能，比如比强度高、耐腐蚀性强，在许多的产业中都具有非常广泛的应用，尤其在***工业、机械等产业，并且铝合金属于有色金属，在应用的过程中需要进行焊接，所以随着科学技术的飞速发展，铝合金的焊接技术的研究也越来越深入。因此，激光焊接技术是科学技术的一大进步。

抛光：

激光焊接作为一种新型的焊接技术，焊接热源直接是激光，既可以避免能源的浪费，又可以***提高焊接的效率。同时，激光焊接把机器人或者是数控机床作为运动系统，减少人员的参与，可以减少劳动力的浪费，提高焊接的效率。激光热源除了具有可再生性和清洁***的优点之外，还可以高度的聚焦和良好性能的传输，因此可以将能量全部汇聚集中于一点，避免热量的散失和浪费。所以，激光焊接能够提高焊接的效率和速度以及焊接的质量。因为激光焊接的光束是通过脉冲或者连续的激光束来实现的，因此当激光束直接照射铝合金的表面时，能够把金属表面的热量迅速扩散到铝合金的内部，使铝合金快速的熔化形成一条焊缝，同时在融化后的金属上形成一种反作用力，最终将熔化的铝合金表面向下凹陷形成小孔。这个小孔具有强大的功效，可以全部吸收激光光束照射时产生的能量，并同时产生高温蒸汽，蒸汽压力与壁层表面的张力形成一种动态的平衡。

1、激光焊接的功率　　激光焊接具有一定的功率，只有当焊接功率达到一定的高度时，才能让焊接得以稳定、持续的进行，否则焊接只能在铝合金的表面进行工作，使得铝合金表面发生熔化，从而焊接不能成功的进行。激光焊接的功率可以达到将铝合金表面以及内部全部焊接的高度，甚至比此还要高，所以激光焊接铝合金级可以提高效率和速度以及质量。　

2、激光焊接的速度　　因激光焊接功***，所以焊接时速度也相应得到提高，焊接的速度不断提高能够使得熔深不断减小，相反，如果速度减慢，就会使铝合金被过度的焊接甚至被焊接穿透，因此，选择激光焊接可以降低焊接失败的比例从而大大降低焊接成本。　　

3、激光焊接的优势　　提高能量密度、提高焊接质量、增加焊接的精度和密度、焊接的效率速度高、焊接成本较低、可以在特殊条件下进行焊接、焊接时对铝合金其他部位影响小。　　

激光焊接在各个领域中的应用　　

1、在石油管道中的应用　　在石油管道中，应用铝合金管道可以增加管道的口径、增厚石油管道的管道壁，让管道能够在一定时间内运输更多的石油。石油的运输具有非常高的危险性，如石油发生泄漏，会造成难以估计的财产损失、人员伤亡以及环境的污染和地下水的污染，因此铝合金管道在焊接时一定要特别注意，提高焊接的质量，激光焊接在此时就可以发挥巨大作用，通过激光焊接，可以控制符合焊接的工艺，可以在不用开坡口的前提下进行焊接的操作，焊接时一次成型，焊缝的质量高，充分的避免了石油泄漏的风险，提高了石油运输的安全性。　　

2、在汽车制造业中的应用　　随着时代的高速发展和人们生活水平的日益高速化，出门乘坐汽车已经习以为常了，并且人们对于汽车的质量要求也越来越高，因此汽车工业也在不断地寻找新型的材料和技术手段提高汽车的质量，激光焊接技术在汽车工业中的到了越来越广泛地应用。美国*将激光焊接铝合金技术引入到汽车制造业当中来，经过一系列的实验，激光焊接的铝合金制造出来的汽车，将薄铝合金激光焊接之后制造成型，不仅大大减轻了车身的重量，而且减少了制造汽车的工序，提高了制作效率，得到了广大汽车制造业的欢迎与青睐。　　

激光焊接加工成为一种成熟的无接触的焊接方式已经多年，极高的能量密度使得高速加工和低热输入量成为可能，焊接强度高，焊缝窄，热影响区小，并且工件变形量小。不断变化的用户需求和高度的国际竞争造成了钣金激光焊接加工领域的向个性化需求转变的趋势。对于用户来说，这意味着产品线的细分程度加大。因此，生产大量相同部件的需求减少，而对于各个产品的准备时间越来越多，而整个加工过程特别是焊接过程，必须适应这个趋势，最合适满足这个需求的设备就是六轴机器人自动激光焊接系统。机器人激光焊接技术会带来很多优点：

1、可以实现激光焦点的功率和大小按加工要求动态地进行调节，同时对加工过程进行实时监控，实现各种各样的应用可能。

2、光束***小，加工精度成倍提高。热影响区极小，焊缝质量高，不易产生收缩、变形、脆化及热裂等热副作用，激光焊接熔池净化效应，能净化焊缝金属，焊缝机械性能相当于或优于母材。

3、采用光纤输送激光，这样一来把能量源和加工设备从空间上分隔可以毫不困难地实现。激光器产生的光能可通过直径很小的光纤传输到距离很远的工位，通过机器人，实现对工件的焊接。

4、一台不锈钢激光焊接机器人可代替3台至4台电阻焊机器人，若充分利用激光焊接技术，加工一个车身，在工装投资、焊件准备、材料消耗、车身密封等方面的费用将减少约200美元，钢材利用率可提高50%。使用不锈钢激光焊接机可省去大量的样板和工装设备，使车间面积减半，节省投资。

目前在金属焊接中出现的一些挑战，比如工件形状越来越复杂，焊接质量要求越来越高，而且加工的个性化需求中的量小样多的订单越来越多，采用机器人自动激光焊接加工系统完全能够应对。

Laser welding has become a mature non-contact welding method for many years. The extremely high energy density has made it possible for high-speed processing and low heat input. The welding strength is high, the weld seam is narrow, the thermal impact area is small, and the workpiece deformation is small. small. The changing demand of users and the high international competition have caused the transformation of sheet metal laser welding to individual demand. For users, this means a greater degree of fragmentation of the product line. Therefore, the demand for the production of a large number of the same components is reduced, and the preparation time for each product is increasing. The entire processing process, especially the welding process, must adapt to this trend. The most suitable equipment to meet this demand is the six-axis robot. Automatic laser welding system. Robot laser welding technology will bring many advantages:
1, the power and size of laser focus can be dynamically adjusted according to the processing requirements, and the processing process can be monitored in real time to achieve a variety of applications.
2, the light beam spots are small, the processing accuracy increases exponentially. The thermal impact area is very small, the weld quality is high, and it is not easy to produce thermal side effects such as contraction, deformation, brittleness, and hot cracking. The laser welding melting pool purifies the weld metal and the weld mechanical properties are equivalent to or superior to the parent material.
5, using fiber optic transmission laser, such a      Laser welding machine principle:
The work of the laser welding machine is to use high-energy pulse lasers to achieve welding. The laser power supply first lights the pulse Xenon lamp and discharges the Xenon lamp through the laser power supply to form a certain frequency and a certain pulse width light wave. The light wave radiates onto the ND3 +: YAG laser crystal through the polymeric cavity, stimulates the Nd3 +: YAG laser crystal to glow, and then after the laser resonant cavity resonates, the wavelength 1064 nm pulse laser is emitted. The pulsed laser is beamed onto the object to be welded after being beamed, reflected,(or focused by fiber optic transmission)
Under the control of PLC or industrial PC, move CNC worktable to complete welding. The pulse laser frequency, pulse width, occupancy ratio, platform speed, and movement direction required for welding can be controlled by single chip microcomputer, PLC or industrial PC, and the pulse laser energy can be controlled by different settings of laser frequency and pulse width.
Laser welding characteristics:

2: Weld formation, aesthetics, no treatment after welding or simply processing process
3: Accurate control, small focal point, high precision positioning, easy to achieve automation
4: Realize welding between heterogeneous materials
5: High weld quality, no air holes, can reduce and optimize the parent material impurities, tissue welding can be refined, weld strength, toughness at least equal to or even more than the parent metal
Application of Weldable Materials and Industry:
Laser welding machines can be used for welding of various metals such as titanium, nickel, zinc, copper, aluminum, Chromium, niobium, gold and silver, and the same materials such as steel and cutting alloys. It can also be used for welding between different kinds of metals such as copper-nickel, nickel-titanium, copper-titanium, titanium-Molybdenum, brass-copper, low carbon steel-copper, etc..
