Crane rail is a common rail on the market, it is the important product that our company provide for the market, the basic production and maintenance skills of crane rail that our company are also known. The following is baisc welding knowledge details of crane rail.

Crane rail virtual welding and fake welding both refer to that the surface of the welding parts is not fully coated with tin layer, not fixed by tin. The reason for this phenomenon is that the surface of the welding part is not cleaned up or the flux is used too little and the welding time is too short.

In the workshop, the machine is no problem, but when the user use after a period of time, the fault is othen happened due to the poor welding and conductive performance, is one of the reason cause the early repair is high, that is “empty welding”.

So what is the cause of crane rail virtual welding?

1, The thixotropic properties of the solder paste are poor or the viscosity of the solder paste recovers too slowly after shear.

2, The heating speed is too fast and the power particle size is too wide.

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