How much do you know about the torque wrench?



Torque wrenches are also called torque wrenches, torque wrenches, and torque adjustable wrenches. They are a type of wrench. According to the power source can be divided into: electric torque wrenches, hydraulic torque wrenches and manual torque wrenches; manual torque wrenches can be divided into: preset type, dial type and digital display.


The main characteristic of the torque wrench is that the torque can be set and the torque can be adjusted.

Torque wrench application:

Torque wrenches are fastening bolts. High-strength bolts can be classified into torsional shear type and large hexagon type. The national standard torsion type high-strength bolts are M16, M20, M22, and M24. Now, there are also non-standard M27 and M30 types. The national standard big hexagonal high-strength bolts are M16, M20, M22, M24, M27, and M30. In general, the tightening of high-strength bolts must be tightened and then tightened, and strict torque requirements must be met at each step. For the initial tightening and final tightening of large hexagonal high strength bolts, constant torque wrenches must be used.

The torque wrench can be tightened and tightened. Its use is to adjust the torque first and then tighten the bolt.

Constant torque electric wrench features:

Easy to operate, save time and effort, adjustable torque.

Torque Wrench Options Reference

1. The ergonomic design of the handle is optimized to hold comfort and greatly reduce the fatigue caused by high-intensity operation.

2, double scale, can accurately set the torque value.


3. When the set torque value is reached, a clear signal is heard and a slight vibration can be felt on the handle.

4, the lock ring close to the tiger's mouth, can avoid misoperation to change the set torque value.

5, wrench length: 990MM.

6, drive the size of 3/4 inches.

7, the minimum scale interval 1.

8. The applied torque should be within 40% to 90% of the torque range of the wrench.

9. Press the lock nut.

Laser Cladding Powder

Nickel Based Laser Cladding Powder

Ni base alloy powder is mainly made of NiCrBSi or NiBSi. Ni-based self-fluxing powder has good wettability, corrosion resistance and high temperature self-lubricating effect, and is used in components with heat resistance, corrosion resistance and thermal fatigue resistance. In general Ni35,Ni45,Ni60 etc can be used for laser cladding, the No means hardness of powder. Inconel 625 and 718 has good corrosion property under higher temperature, also widely used for laser cladding process.


Cobalt based Laser Cladding Powder

Cobalt-based alloy powder is the cemented carbide resistant to various types of wear and corrosion as well as high temperature oxidation. That is, the so-called cobalt-chromium-tungsten (molybdenum) alloy or Stellite alloy cobalt-based alloy is mainly composed of cobalt, containing a considerable amount of nickel, chromium, tungsten and a small amount of molybdenum, niobium, tantalum, titanium, Alloying elements such as lanthanum, and occasionally a class of alloys containing iron.

Co-based self-fluxing alloys have good high temperature performance and wear resistance and corrosion resistance, and are used in petrochemical power, metallurgy and other industrial fields where they are wear-resistant, corrosion-resistant and high-temperature resistant.

Laser Cladding


Iron based Laser Cladding Powder

The work pieces required for laser cladding and manufacturing in the actual industry are mainly carbon steel and cast steel. The Fe-based alloy is close to the base material in composition and has good wettability. The advantage of Fe base powder is lower cost and good wear resistant of cladding layer. As a result, it`s the most widely used for laser cladding process. It is suitable for parts that require local wear resistance and are easily deformed.

Laser Cladding Work Part



WC blended Laser Cladding Powder

Tungsten carbide blended with Ni alloy powder is the best choice for wear resistant work piece. This unique process can bring excellent wear, corrosion and high temperature resistant. Our blend powder can achieve different portion of WC from 35% to 60% without crack under suitable cladding parameter.
