The three kinds of leak detector leak port, all the SF6 gas bottle with a rate of 1 cm / sec measurement results in the following table. Due to experimental conditions, the moving speed of the sensor can not be fully consistent with the amount of gas leakage is not necessarily exactly the same, but the experimental results can be seen the following conclusions: even if the static sensitivity is up to 0.001ppm, the response time of less than 1.5 seconds, selective good using laser photoacoustic spectroscopy detection technique, LLD-100 and its dynamic sensitivity also 1ppm. The sensitivity of 1ppm response time of 5 seconds of infrared leak detector test results is much smaller than the actual value. The laser beam emitted from  waterproof flashlight   is clear and visible.
The head of the strip before the volume of the end of the strip and roll it in place, both the rise in import / export segment Looper roll, strip formed Looper, as shown in Figure .3-2. MCD strip welder comes on the device before and after the strip to adjust import and export plate to compress the strip before and after volume, as shown in Figure 3-3. Double-cut shear, under the blade volume strip tail and the head of the latter half of the volume strip shearing and punching, as shown in Figure 3-3. Laser welding the head to drop the compression strip welding, Figure .3-5 shown. Figure .3-6 crescent shearing strip welds. Strip running to the crescent cut the cut edge of the weld, as shown in Figure .3-6. Automatic includes the process of laser welding work. It is not suggested that the customer use waterproof flashlight continuously for a long time.
The manufacturing process is the most important aspects of the quality and level of C-GIS products, the gap between domestic products and foreign products is also reflected in the process. The welding of the C-GIS product box affect product quality and production efficiency of key processes, welding is necessary to ensure the strength and precision of the box, but also to ensure air tightness. The commonly used argon arc or gas welding, heat input and slower welding, stainless steel plate heat transfer quickly, there is always welding deformation. Welding deformation of the existence of assembly debugging adversely affect the tightness of welding can not be effectively guaranteed.  waterproof flashlight  is straight and powerful, especially the waterproof flashlights.
The laser welding machine, Shenzhen Laser Marking Machine, Dongguan, laser marking machine. A current trend is to use the "U" shaped ribs, laser welded together through the cabinet side panels. With this welding can minimize the deformation of the stainless steel side panels, while reducing the difficulty of fixture design and manufacturing. Laser welding of stiffeners. Laser welding inflatable cabinet box. Inflatable cabinet box before laser welding, TIG welding of the way the various stainless steel side panels stitching together, then the laser seam welding to ensure air tightness and welding strength. Most enterprises to adopt carbon dioxide laser average power of 4kW, welding depth is 3 ~ 4mm, welding speed 2.5m/min - 4m/min. The green  waterproof flashlight  is easier to be affected by the environment.
