The height alignment and rail crown must be set using either a 1 m straight edge or the crown
check unit according to data sheet.
The final alignment on the rail must be checked after the weld has cooled down and, if necessary,
the amount of crown adjusted for further welds.
Horizontal alignment must be carried out on the running edge using a 1-m straight edge.

10.1.2 Dimensional check : All welds shall be inspected using standard 1 m and 10 cm straight edges and feeler gauges, as shown in figure 8 (a) to 8 (j) for compliance of geometrical standards as given, in. Annexure-IV. Welds not meeting these standards,, if rectifiable by grinding, can be re-ground, failing which they shall be rejected - http://www.indianrailways.gov.in/railwayboard/uploads/codesm...
Repairs can be done by welding of worn rails on the top and side surfaces, in curves and straight sections of any length, while keeping the original geometric shapes of rail crown, high quality of weld layer of parameters close to those of the base material being taken for granted. - http://www.kmt.cz/en/technologie-navarovani-vyhybkovych-souc...
