The battery needed for this kind of laser pointer is cell button.
5kW transverse flow CO2 lasers on a single channel or multi-channel scanning preset at the Co-based matrix alloy powder. Correlation, obtained by the melt layer and plasma welding and laser melting layer defects in low yield. Organized crime, uniform, fine grain size and composition of the dilution rate is smaller, hot little effect on the matrix, the melt layer hardness and higher strength and toughness. The performance test proved that laser melting layer has a higher corrosion resistance. A large number of petrochemical reactors and nuclear power plants use a variety of acid-resistant stainless steel valves. Various media in the production process with a strong caustic and even radioactive corrosion results not only makes the valve sealing surface is damaged, significantly shorten valve life, and the media leakage may cause downtime. Two pieces of laser pointer are needed for this kind of laser pointer .
Pollute the environment or cause a serious accident. The quality of the sealing surface is an important indicator of assessment of the basic performance of the valve, stainless steel valve sealing surface requirement is even higher. The stainless steel valve sealing surface of the high-parameter general intensive surfacing directly on the body, and not a mosaic structure. High-power laser beam and the special role of the material allows the substrate surface alloy layer to meet the designers requirements, the performance of this alloy layer is not only much better than the stainless steel substrate, and superior to the traditional plasma spray welding layer and a variety of heap The performance of the solder layer. This kind of laser pointer is in the pen shape.
We 20HJ63-20P stainless steel nuclear valves and urea production line the methylamine combination valve sealing surface with a laser cladding processing, and a comparative analysis with conventional plasma spray welding. Test with the valve closed for 20HJ63-20P valve materials for 1Cr18Ni9Ti steel; 3W-2BJ1 methylamine pump inlet and outlet valve, the material for Cr18Ni12Mo3Ti steel. Sample box specimens (19mm × 15mm × 10mm) ring specimens (38 × 28mm × 10mm) two kinds. HGL-90 the 5kW cross flow CO2 laser laser cladding alloy powder 2132 phenolic resin powder + ethanol reconcile the pre-coating and drying on the machined surface, pre-deposited layer thickness of about 3mm. The appearance color of laser pointer can be customized as red.The body color of laser pointer is white
Laser cladding, CNC two-dimensional simultaneous machining stage box specimen using multi-channel scanning, each amount of overlap is 50% of the laser spot diameter. Ring specimens in CNC rotary table, the single-channel scanning. Cladding process parameters: laser power P = 3000 ~ 3400W, scan speed v = 8 ~ 12mm / s, spot size ≈ 5mm. The facula energy form of Gaussian distribution. Plasma spray made the DP-500 powder plasma arc welding machines, welding torch LFH type, powder feeding method, the surfacing layer of about 3mm. The material color of laser pointer is black.
