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.

On May 10, 2011, FAW Jiefang Xichai Engine Factory held a grand ceremony for the first batch of millions of kilometers without overhauling users. Chairman of the FAW Group Corporation, party secretary Xu Jianyi, deputy general manager Dong Chunbo, relevant leaders of the FAW Jiefang Company, and more than 300 people from the Liberation Aowei dealers, service stations and user representatives from all over the country witnessed the liberation of the Aowei engine for a million kilometers without major repairs. miracle. 
On December 20, 2003, Aowei, a four-valve heavy-duty diesel engine with independent intellectual property rights and core technology developed independently by FAW Group, went offline at Xichai. As soon as Aowei appeared, it quickly triggered a vigorous and independent thought of cooperation in the industry.
In 2004, the Liberation Aowei heavy truck equipped with Xichai Aowei Engine was officially put on the market. Since then, it has opened a new era of independent innovation and upgrading of heavy trucks in China. Buy a car to buy a liberation car, choose the machine to choose Aowei machine selling point, has been accepted by the majority of users at home and abroad, Aowei heavy trucks to increase sales at an annual rate of 60% increase in the market, continue to maintain the hot trend of supply in short supply, has so far exceeded 250,000 units.
Under the influence of Aowei Engine's good reputation, FAW Xichai Factory entered a golden period of new development. The scale of production and sales rose from 150,000 units in 2004 to 436,000 units in 2010. 
In the first batch of Aowei Million Kilometer No Overhaul User Awards Ceremony, Jia Cuihua of Wuhan Tianshun Automobile Transportation Co., Ltd., Hainan Da Fu Hao Passenger Transport Co., Ltd. Su Qiongyu and other users were fortunate enough to be among the millions of users without maintenance in Aowei. The top 20 were rewarded with FAW Xichai. Jia Cuihua and Su Qiongyu received super mileage awards, each received 50,000 yuan in prizes, and the remaining 18 users earned excellent mileage awards, each receiving 10,000 yuan.
Su Qiongyu, a user from the southernmost city on the seashore of China, said that he had driven all brands of cars in China, and he still felt that Aowei engines were the best. He has been using the Xicca passenger bus for some years. He has already achieved three million kilometers without major repairs. He believes that the breakthrough can be achieved through the quality and technical level of the product. Aowei’s fuel-efficient, durable and reliable vehicles enable Kai Aowei’s drivers to receive a few hundred yuan per month for fuel-efficient bonuses. This is the benefit Xichai brings to users.
One million kilometers of FAW Xichai Engine is not overhauled. It is the pride of FAW and the expectation of FAW users. Million kilometers without major repairs are the result of FAW's autonomy. It is also the result of the support of customers. Millions of kilometers are not overhauled. It is a milestone for FAW's own products and a new starting point for FAW's product strategy.
Aowei completes the realization of one million kilometers without major repairs. Once again, it demonstrates the strength of FAW's independent products. FAW Jiefang Company Wuxi Diesel Engine Factory will take the one million kilometers without major repairs as a new starting point, in order to accelerate FAW Group's 12th five-year strategy and FAW. Development makes greater contribution.
