Tubular tungsten carbide welding rods are a type of welding consumable used for hardfacing applications. They are made by filling a tubular steel rod with a mixture of tungsten carbide particles and a binder material.

“I also have statistics on the quality of Weichai, and if I provide it to the media, I can write more sensational reports. The quality of the machinery production process is unavoidable. Competitors should not exaggerate their words. Smashing each other."
Yesterday (20th) afternoon, Liu Wei, Director of the Technology Center of China National Heavy Duty Truck Group Co., Ltd. (a listed company: GSI, 000951, SZ) held a quality monthly report from Weichai Power (2338.HK). "First Financial Daily".
The previous day, a media report titled "China's heavy-duty engine batch failure investigation and firewood separation is the root cause" of the report caused China's heavy truck angry. China National Heavy Duty Truck believes that this is the role played by rival Weifang Diesel.
According to the aforementioned report, CNHTC has caused nearly 500 engines to be scrapped due to defects in the engine connecting rod processing technology, and the engine may become the weak point of China National Heavy Duty Truck.
Cai Dong, general manager of China National Heavy Duty Truck Co., Ltd. did not deny the problem of the engine connecting rod breaking when answering this reporter's question. But he said that it is not like the 500 in the media report. In fact, as of now, a total of 31 links have broken. Each engine has six connecting rods. In the first half of the year, it produced a total of more than 30,000 engines, and there were nearly 200,000 connecting rods. The percentage of fractures was very low. Now the connecting rod process has been properly solved.
Cai Dong said that last year Sinotruk had hosted the Hangzhou engine plant in Weichai. At that time, the Hangzhou engine plant had been using the "tapping" process for the connecting rod process, and Weichai had adopted the "squeeze" process because it was chopped wood at that time. As a leader, Hangfa has changed to a "squeeze" method. After the heavy-duty engine was produced in Jinan at the same time, the process was docked on March 29 this year. As of April 2, the process conversion process discovered that a certain percentage of connecting rods were in trouble. We found that we took measures in time and changed it back. The "tapping" process.
According to the data provided by China National Heavy Duty Truck, China National Heavy Duty Truck produced and sold 31,000 various types of automobiles in the first half of this year, an increase of nearly 35% compared with the same period of last year. The market share increased by 4.5 percentage points and exceeded 20%.
"If our engine has quality problems, will there be such a good sales performance?" Cai Dong asked.

The tungsten carbide particles provide exceptional hardness and wear resistance, making them suitable for applications where the welded surface needs to withstand high levels of abrasion, erosion, or impact. The binder material helps to hold the tungsten carbide particles together and facilitate the welding process.
Tubular tungsten carbide welding rods are typically used in industries such as mining, construction, oil and gas, and agriculture, where equipment and machinery are subjected to harsh operating conditions. They can be used for hardfacing various components, such as drill bits, crusher hammers, wear plates, and cutting tools.
The welding process for tubular tungsten carbide rods is similar to other types of welding, such as shielded metal arc welding (SMAW) or gas tungsten arc welding (GTAW). The rods are typically welded using a high heat source, such as an electric arc, to melt the rod and create a strong bond with the base metal.
Overall, tubular tungsten carbide welding rods are a popular choice for hardfacing applications due to their exceptional hardness and wear resistance properties. They help extend the lifespan of equipment and machinery, reducing maintenance costs and downtime.
