Thermit welding of chromium-vanadium railsteel
Abstract:
Thermit welding techniques are discussed with particular reference to short preheat cycles and its suitability to the welding of high-strength chromium vanadium rails. The composition of the Thermit steel used is adjusted to match the phase-transformation characteristics of chromium-vanadium steels. To avoid a martensitic or bainitic structure in the finished weld, the cooling cycle must be controlled.
Keywords:
