Micro welding or micro-dimensional welding is a widely used and accepted process in today’s industry. The process is carried out under a welding microscope which helps to weld small areas with maximum accuracy.
Welding microscopes are specially designed to offer great control of part positioning and welding placement. They are provided with fine internal crosshairs, which helps to align the hardware element and the filler at the exact position. The weld speed of microscopic welding can range between 10 and 30 inches/minute. In laser micro welding, the microscopes help to focus the laser beam at a specific point.
There are many advantages of using microscopes in welding. Microscopic welding often results in a low-distortion and accurate joining process. It can also minimize contamination of the web joint. The microscopic images of welding can be captured by connecting the welding microscope to a video or photo camera using a photo-adapter. The microscope can also be plugged into a computer to record and process the images.
Almost all the laser welding systems come with in-built microscopes. Usually, a high quality stereo microscope – with a magnification factor ranging between x16 and x25 – is used. It offers clear viewing for precise welding. An optional projection microscope can also be used.
Many models of micro welders are also available, which use low-amp welders and welding microscopes. The welders can be placed on the desired location of the weld, without affecting the shape or size of the material. Micro welders are mainly used for precision welding of jewelry. Some micro welders can be used to repair molds such as plastic injection molds, die cast molds, and rubber processing molds.
