Free from Expert Skill of Rail Gas Pressure Welding
The heating burner is connected with a coupling rod to the swing part, which is reciprocated by means of a ball screw driving mechanism.
It is possible to set up “swing start time”, “swing amplitude”, “swing speed” of heating burner.
This device also has the mechanism to make the heating burner follow the movement of the weld interface.
Automatic Swing Device
Automatic Swing Device can be applied to gas pressure welding execution and achieve the automation of heating process.
This device can be attached to the gas pressure welding machines which are rail web clamping type.
Example of burner swing pattern for JIS 60kg standard carbon rail
