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.

Let each harvester “safe†to ensure the summer harvest is completed smoothly
[China Agricultural Machinery Industry News] Now is in the busy season of summer harvest, we must do a good job in the supervision and management of agricultural machinery safety production, especially during the summer harvest period, we must effectively prevent and contain the occurrence of agricultural machinery safety accidents. In order to effectively improve the safety technology status of the seventh division, the second and third group of combine harvesters, reduce the hidden dangers of agricultural machinery safety, and ensure the safe completion of the harvest of the 10,000-mu wheat harvest. On the morning of June 17, the first two-third group agricultural machinery department to the whole group 8 The combined harvester will carry out centralized inspection and verification to ensure that each harvester achieves a good working condition and guarantees the successful completion of the summer harvest.
In the trial, the supervision agencies of the No.1 and No.3 Agricultural Machinery Supervision Department strictly carried out the inspection according to the "Technical Specifications for Safety Supervision and Inspection of Combine Harvesters". The inspection and inspection items include locomotive steering, braking, lighting, safety shields, complete fire protection facilities, and transmission. The reliability, sensitivity, etc. of the organization. Through inspection and examination, the first is to ensure that each locomotive participating in the summer harvest work has a good working condition and safe and reliable working performance, ensuring the safe operation of the locomotive in the summer harvest work. Under the premise of short time and heavy tasks, the warranty is guaranteed. The amount of completion of this summer's harvest work. The second is to strengthen the safety education of large-scale agricultural machinery drivers and to improve the safety of drivers in production and production. The third is to strengthen the service awareness of large-scale agricultural machinery personnel to ensure that the fruit harvest of the workers' harvest is returned.
In the inspection and inspection, we can see that the combine harvesters of the first two or three regiments have been inspected and maintained in place, ready to be delivered, and fully prepared for the successful completion of the wheat harvest work of this group this year.
Liang Deqing, the driver of the two-three group combine harvester, said with confidence: "The summer harvest has started immediately. Now that all of our harvesters are in place, we can go to the ground at any time, and we will do a good job in this summer's harvest."
