What is brazing? How is brazing classified? What are the characteristics of the brazed joint form? Brazing is to use a metal whose melting point is lower than that of the base material as a brazing ma...

The electric welder uses the high-temperature arc generated by the positive and negative poles in an instant short circuit to melt the solder and the material to be welded on the electrode to achieve ...

1. Reasonable design and free adjustment. The electric welder can select different discharge frequencies according to different metal materials to achieve the best repair effect. 2. The heat affected ...

Direct cause analysis The kiln system Q235-A is made of steel and has good electrical conductivity. The main responsibility of the accident is that He has no special operation qualification certificat...

There are three reasons for this deformation: 1). The body and the desired fusion or cover cannot match each other due to angle or curvature. 2). The product wall thickness is thin (within 2m/m) and t...

In the case of tungsten argon arc welding, since the argon protective layer is flexible, it is easily damaged by external factors and its protection effect is mainly related to the following factors: ...

Many of the properties of welds can be tested by weld inspection, some of which are related to weld size and others to weld defects. Weld size is often extremely important because it is usually direct...

The reason for the internal original damage is that the high-intensity ultrasonic energy is directly or indirectly transmitted to the damaged part. The solution is as follows: 1. Early ultrasonic vibr...

Ultrasonic non-woven mask spot welding machine principle The non-woven mask spot welder converts 50/60 Hz current into 20 kHz by ultrasonic generator. The transducer is again converted into a mechani...
