The so-called heavy rail is a common rail product in the market today. It is the key steel product that our company provides for the market all year round. The basic production of the heavy rail is also mastered by the maintenance skills company. The following are the details of the basic virtual welding basics of heavy rail.

Crane rail virtual soldering and false welding are both the surface of welding parts not fully coated with tin, not to be fixed by tin. This phenomenon is caused by the fact that the surface of the welding parts is not cleaned or used too little and the welding time is too short.

There is no fault in the whole machine installed in the workshop, but after the user uses it for a period of time, the malfunction caused by poor welding and poor electrical conductivity often occurs, which is one of the reasons for the high repair rate in the early stage, which is called "virtual welding".

So what is the cause of heavy rail virtual welding?

1. The thixotropy of solder paste is too poor, or the viscosity of solder paste recovers too slowly after shear.

2. The heating rate is too fast and the particle size of the powder is too wide.

3. The metal load or solid content is too low, the surface tension of the flux is too small.

Knowledge is the basic virtual welding crane rails above details, hope the broad masses of customers friend easy to understand, to improve enterprise efficiency, to ensure the safety of enterprise production to provide support to help.
