激光焊接有其独特的优势和激光扫描焊接的定义
 

激光焊接有其一起的优势:能量密度高、焊接速度快、焊接质量高(深宽比可达2—2)、焊缝组织细密、强度高;2.热影响区小、焊后资料变形小;简单完结自动化,前进生产率;可焊接难以接近部位,实施远距离焊接;与数控作业合协作,可完结凌乱曲面和薄壁异形管的焊接;污染与任何腐蚀;激光还可用于不同类型、异种金属之间的焊接。

激光焊接有其独特的优势和激光扫描焊接的定义

激光扫描焊接的定义: 在机器人的第六轴上装置一个振镜扫描头,从激光源宣告的激光光缆的结尾直接连接到扫描头上,在扫描头中两到三个可调镜片可以将反射的激光射到工件上。当镜片摇晃时,激光束从一个点到另一个点进行跳动,实施焊接。关于机器人手臂来说,不必在每一个焊点初步和间断,可以直接运用扫描头精确定位。激光扫描头到工件表面的距离可以逾越500mm,当焦点直径为0.6mm的时分,加工区域大约为190mm×320mm的椭圆形区域。


这也是最有可能用于该系统的作业距离和作业范围。由于机械臂在焊接进程中有一个大于90度的重定位动作,如果作业距离过大,会导致在重定位进程中不必要的时间浪费。如果缩小作业距离,也意味着小的作业区域,焊接工艺的连续性和激光的利用率都会被大大约束。大作业距离的另一个长处是延伸了镜头的维护玻璃的运用寿数,气幕改善之后,维护玻璃的运用寿数更是大大延伸,可用于逾越15000件的焊接。

Laser welding together has its advantages: high energy density, high welding speed, high welding quality (aspect ratio can reach 2 - 2), weld fine microstructure and high strength; 2. small heat affected zone and welding deformation data; end simple automation, can advance productivity; welding is difficult to close position, the implementation of long-distance welding; numerical control operations and collaboration, welding end surfaces and thin messy shaped pipe; any pollution and corrosion; also can be used for laser welding of dissimilar metals between different types.


The definition of laser scanning welding: a scanning head device in sixth axis robot, at the end of the laser from the laser source of the cable that is directly connected to the scanning head, in a scanning head two to three adjustable lens can be reflected laser light onto the workpiece. When the lens is shaken, the laser beam runs from one point to another, and the welding is carried out. For robot arm, it is not necessary to use the scanning head to precisely locate each spot. The distance between the laser scanning head and the workpiece surface can exceed 500mm, and when the focal diameter is 0.6mm, the processing area is about 190mm * 320mm elliptic region.


This is also the most likely to be used for the operating distance and operating range of the system. Because the manipulator has a repositioning action greater than 90 degrees in the welding process, if the distance is too large, it will lead to unnecessary waste of time in the relocation process. If the operation distance is reduced, it also means that the small operation area, the continuity of welding process and the utilization rate of laser will be greatly restrained. Another advantage of large operating distance is the extension of the lens glass using his maintenance, improve maintenance after the air curtain, using his glass is greatly extended, can be used for welding over 15000 pieces.
