Do you know why alloy heads on bullet teeth tend to fall off?

Do you know why carbide tips of bullet teeth tend to fall off early and midway through the process?

What causes tungsten carbide tips to fall off easily late in the process in mining tunneling construction?

The alloy head is always falling off, mainly caused by brazing process and pre-welding treatment is not in place.It is mainly divided into the case that the carbide tips falls off in the early, middle and late stages of the use process of bullet teeth.

The main reasons for the alloy head falling off in the early and middle stages of the cutting picks usage

 Poor weld quality, low strength

Cutting teeth body processing size control is not strict, resulting in weld gap is too large or too small, leading to solder flow difficulties, resulting in alloy head squeeze, lack of welding.

How to solve this problem?

In response to the situation of early falling off, Zhuzhou Xinda Machienry Technology Co Ltd firstly, strictly control the diameter of the inner hole of the cutting pick body to ensure the right size of the weld, and secondly, adopt a unique welding process to ensure the even flow of flux.

As you can see, the alloy saturation of our cutting teeth reaches more than 98.5%, which is exceed much than the highest industry standard at present.

To solve the problem of falling off at the later stage of the cutting tooth

It is because of the excessive wear of the front end of the tooth body, which makes the carbide tip protruding too much, and the weld area decreases, which leads to insufficient strength of the brazing weld, resulting in the falling off of the alloy head, so to solve the problem of falling off at the later stage of the alloy head, in addition to improving the quality of the brazing and weld strength, more importantly, it is to improve the front end of the body of the tooth cut-off wear resistance, the wear-resistant welding technology of the Zhuzhou Xinda Machinery Technology Co Ltd cutting tooth has obtained the national patent, and has greatly improved the wear-resistant performance of the bullet teeth Enhance the wear-resistant performance of the cutting teeth, can ensure the synchronous wear of the wear-resistant layer and the alloy head, ensure that the alloy head will not fall off.
