Product Introduction
SINCHOLD thermite welding main working principle: by light flux, producing high temperature liquid metal steel in a short time, fusing with preheating rail end , after natural cooling to form a whole. The quality after welding meets the mechanical property of the thermal welding joint. We offer a full range of rail welding kits to suit all rail sections including Worn Rail Welding and Wide Gap Welding.(The quality indicators of thermite welding joint can be referenced to TB/T1632.3-2014 Standard)


Product Feature and Application
The rails in China using thermite welding technology to make seamless connection is developed with the acceleration of railway. This new technology has been rapidly extended to the seamless welding of crane rails in various fields, such as mining, coking industry, goods yard ,port ,wharf and so on. It has solved the damage of the crane equipment, track, bed and girder for a long time.

Characteristics and Advantages of Thermite Welding:

The current of the welding point is equal to the wire.Welding points are permanent and will not cause high resistance due to loose or corrosion.Welding points are like copper, which is more tenacious than copper itself, and is not affected by corrosive products.Welding points can withstand repeated surges (failure) current without degradation.The welding operation method is simple and easy to handle.Portable and convenient to carry.When welding, no external power source or heat source is required.The quality of the welding can be checked from the outside.It can be used for welding copper, copper alloy, copper plated steel, various alloy steel including stainless steel and high resistance heating heat source material.
