Abstract
The processes at the weld joint in local heat treatment are simulated. At heating rates typical of shop conditions, the critical points of low-carbon low-alloy steel are determined for pipe of strength class K52. Local heat treatment of such pipe welded by high-frequency current is proposed to increase the impact strength and resistance to brittle failure of the weld seam at negative temperatures.
