MFG Guide

At present, in the laser welding machine industry, there are many manufacturers using stainless steel laser welding machines to weld stainless steel materials, so what is the effect of using stainless steel laser welding machines? The welding seam effect is very good. For example, many commonly used 304 stainless steel materials use laser welding machines. Compared with traditional welding, low-power pulse laser welding machine has the advantages of high power density, concentrated energy, small heat input, narrow welding seam, small deformation, small spot after laser focusing, accurate positioning, etc., which makes laser seam welding It is more suitable for welding small metal parts. Laser welding of ultra-thin stainless steel materials, because the material is thin, the perforation is easy to vaporize, and a continuous, non-burn-through weld must be obtained. The point is to control the parameters more precisely. Because of its extremely small thermal conductivity, stainless steel is only about one-third of that of ordinary low-carbon steel. It is less stressed during welding. Therefore, uneven stress and strain will be generated when local heating and cooling are performed. Longitudinal shrinkage produces a certain amount of pressure on its outer edge, and excessive pressure will cause its deformation, which not only affects the appearance, but also affects the quality of the steel plate. In addition, problems such as overburning and wear will occur. Welding current, pulse width, pulse frequency, etc. are the main parameters that affect the quality of laser welding, and their effects are as follows: One: With the increase of current, the width of the welding seam gradually increases, splashes gradually appear during the welding process, and the surface of the welding seam appears oxidized and rough. Two: As the pulse width increases, both methods can get the same result. The change of pulse width has a great influence on the effect of laser welding of ultra-thin stainless steel plates. A slight increase in the pulse width will cause the sample to oxidize and burn through. Three: As the pulse frequency increases, the overlap rate of the solder joints increases, and the width of the solder joints first increases, and then basically remains unchanged; through observation, it becomes more and more smooth and beautiful. However, when the pulse frequency increases to a certain value, the weld spatter is serious, the weld joint becomes rough, and the upper and lower surfaces of the weldment are oxidized. Four: The positive defocusing method should be adopted for laser welding of ultra-thin plates. With the same defocusing amount, the surface of the plate obtained by positive defocusing laser welding is smoother and more beautiful than the negative defocusing surface. Using a high-energy laser beam, a stainless steel laser welding machine locally heats the welding area to melt the material to achieve the purpose of welding. The advantages of this welding method are: non-contact welding, welding more flexible; high welding efficiency and fast speed ; Good welding effect, narrow range, small deformation; easy to realize automatic welding, and beginners can start working after simple training.
