Laser cutting machine equipment as a new type of tool is now more and more mature to use in various industries? Including laser cutting machine, laser engraving machine, laser marking machine, laser welding machine and so on. So how does laser cutting work? How does laser cutting differ? First, the energy of the laser is concentrated in the form of light into a high-density beam. The beam is delivered to the work surface, generates enough heat, melts the material, and removes the molten metal directly from the high-pressure gas coaxial to the beam. This shows that the laser cutting process is essentially different from the machining of machine tools. It uses the laser beam emitted from the laser generator? Through the optical system? Focusing on the laser beam irradiation conditions of high power density? Laser heat is absorbed by the workpiece material? The temperature of the workpiece rises sharply? After reaching the boiling point, the material begins to vaporize and form holes • The flow of air with high pressure? As the beam moves relative to the workpiece, the material eventually forms a slit. The process parameters (cutting speed, laser power, gas pressure, etc.) and trajectory during the slitting are all controlled by the numerical control system. The slag at the kerf is blown by the auxiliary gas with a certain pressure. In general, the quality of laser cutting can be measured by the following six criteria. 1. Cutting surface roughness Rz 2. Cutting slag size 3. Trimming perpendicularity and slope u 4 cutting edge corner size r 5. After the stripe drag n 6.

A variety of CNC cutting machine and CNC cutting equipment, a variety of cutting machine models, let the optional! Official website: / PTA Powder
Main application:Repair and
strengthen workpiece surface, significantly
Welding method:PTA welding
Main equipment:PTA welding
machine
Flame core temperature: about 10000℃
Technological characteristics:PTA has high
temperature, concentrated energy, stable combustion, small heat affected zone,
fast welding speed, high production efficiency, easy to obtain low dilution
rate of surfacing layer, surfacing layer and workpiece matrix are metallurgical
bonding,, bonding strength is high.
PTA welding technology is one of surface
strengthening methods, which has high deposition rate, low dilution rate, and
could be applied with many kinds of powder. The manufacturing craft of PTA
powder is normally gas atomization, which reduces satellite of powder. We
supply 4 main categories of PTA powder: Nickel-based alloy powder, Iron-based
alloy powder, Cobalt-based alloy powder and Mixed Powder.
Nickel Based Alloy Powder possesses high
temperature resistance and wear resistance, it is the most popular alloy powder
applied by PTA welding both domestically and internationally. Coating hardness
is within the range of HRC 30-60. It could be applied to various industries
like agriculture, plastic, paper, marine and steel making where wear and
corrosion protection needed. Some examples are plunger, moulds, pump leaf and
screw.
Iron Based Alloy Powder is more widely used
and a more economic choice. With high abrasive resistance, it is more commonly
applied to mining tools, drilling tools and mixers of iron and steel making
industry, coal industry, shaft, oil and energy industry.
Cobalt Based Alloy Powder is recommended
for corrosion and oxidation resistance, with better hot hardness values than
equivalent Nickel based alloy powder. It is widely applied to steel making
industry, coal industry and mining industry.
Mixed powder mainly refers to NiCrBSi
mixing with other hard-phase powder such as cast tungsten carbide and other cemented
alloy powder, which allows the powder better hardness around HRC60 and
excellent abrasion resistance.
Mixed powder is more often used for mining
equipment for oil sands, lignite, oil drilling tools, excavator buckets,
extrusion screws for plastic processing, grain and oil processing, etc.
