Abstract:
High carbon welding electrode is used in the welding of high strength steel using gas shielded arc welding techniques whereby a plurality of beads of molten weld material join together rail ends or fill a slot in a rail for repair purposes, the high carbon electrode avoiding adjacent soft and brittle areas across a weld fusion line which result from migration of carbon from the carbon rich high strength steel to the lower carbon weld deposit.
