Advantages of stainless steel, laser welding machine: Compared with conventional welding, low-power pulsed laser seam welding with high power density, energy concentration, heat input is small, narrow and weld distortion, etc, and focusing the laser beam can be obtained after a small spot, can be precise positioning, these features make a laser welding seam welding method is more suitable than the other for welding the small size of the workpiece. For the laser welding of thin stainless steel material, because the material is very thin, it is easy to vaporize perforated, to obtain a continuous, non-burn-through weld. The key is accurate control of the parameters. The main parameters affecting the quality of the welding laser welding current, pulse width, pulse frequency, etc., which mainly affect the results as follows: (1) as the current increases, the weld width increases, the gradual emergence of spatter during welding, the weld the surface oxidation, and a rough sense. (2) increases with the pulse width of the weld width also increases. Impact of changes in pulse width laser welding of stainless steel thin plate effect is very significant. Small pulse width is increased, the sample may lead to oxidation and burn. (3) increasing the rate of spot overlap with the pulse frequency increases, the first weld width increases. After essentially unchanged. Under the microscope, more smooth and beautiful weld. However, the pulse frequency is increased to a certain value, welding spatter seriously, weld becomes rough, and the upper and lower surfaces of the weldment appear oxidation. Laser welding (4) thin plate material appropriate to adopt a positive defocus, in the case of the same amount of defocus, being away from the weld surface confocal laser welding to get smooth and beautiful than when negative defocus. Stainless steel are the following: Model 301 - scalability for molding products. It can also be rapidly hardened by mechanical processing. Good weldability. Abrasion resistance and fatigue strength than 304 stainless steel. 302 Model 304 with corrosion resistance, due to relatively high carbon intensity and therefore better. Model 303 - by adding a small amount of sulfur and phosphorus to more than 304 cutting. Model 304- general model; that is 18/8 stainless steel. GB grades 0Cr18Ni9. Model 309 - 304 - better temperature resistance. Model 316 - After 304, the second most widely used of steel, mainly used in the food industry and surgical equipment, add molybdenum to obtain a special corrosion-resistant structure. Than the 304 because it has better resistance to chloride corrosion and thus as "marine steel" to use. SS316 is often used to fuel recovery. 18/10 grade stainless steel is usually in line with the application level Model 321 in addition to the added titanium elements to reduce the risk of material other than the corrosion of the weld performance similar to 304. 400 Series - ferritic and martensitic stainless steel type 408 - good heat resistance, low corrosion resistance, 11% Cr, 8% of Ni. Model 409 - the cheapest model (BAR), commonly used as automobile exhaust pipe, is a ferritic stainless steel (chrome steel).
