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.

[China Agricultural Machinery Industry News] UAVs were first used in the military field. With the development, more and more are used in the civilian sector. Nowadays, the term aerial photography of drones has gradually ringed more and more people's doors and walked into our side, becoming a new world of photography after SLR and sports cameras. The drone is not only used in the college entrance examination, but also on the Dragon Boat Festival. It is also used to assist the traffic police to carry out road duty enforcement on the highways in the province.
Dragon Boat Festival Holiday: Traffic Police Assistant arrives at the drone to open the road monitoring mode
During the "Dragon Boat Festival" small holiday, the Sichuan Public Security (Weibo) traffic police will enable the drone to carry out road enforcement on the highways in the province. Including the use of drones to view road traffic congestion, fixed-point monitoring of highway traffic, to provide timely and accurate information support for the highway to block the smooth. The traffic police will also use drones to capture traffic violations such as emergency lanes.
Sichuan police traffic police reminded that in the event of traffic congestion, accidents and other emergencies, the highway emergency lane is the "life channel" for rescuing the wounded, quickly handling accidents and timely recovering traffic. Please consciously abide by the traffic laws and regulations, and drive safely and safely. The traffic-intensive road sections should be lined up in order according to the order. Do not occupy the emergency lanes at will. For illegally occupying the emergency lane, a fine of 200 yuan will be imposed on it and a penalty of 6 points will be imposed.
