What is the upsetting amount of rail?
The data is an important parameter in welding process adjustment in, although the parameters according to different parameters change with the pre process space is relatively loose, but upset the amount is too small, too much will not be able to form the quality of welded joints.
Upsetting is the amount of deformation produced during the top upsetting of the two rail to be welded.
Top forging is a very important link in the welding process of rails. The link is to increase the feeding force, so that rail rapid delivery, so as to achieve the elimination of debris, eliminate defects, forming a good welding process.
