| Abstract | Arc welding boron-containing steel is accompanied by the serious difficulties caused by metal red-short. The acceptable option of automatic welding is developed for ferritic chromic stainless low-carbon steel 04H14T3R1F-Sh (ChS-82Sh) under ceramic gumboil with the use of LFS lining tape. Steel is applied as neutron-absorbing material for production in cooling ponds storage racks of the irradiated nuclear fuel (INF) with the content of uranium U-235 < 5%. It is shown that in metal of a seam structural and phase structures of a matrix and nonmetallic inclusions are well combined, ratios titanium-boron and titanium-boron-chrome are more favorable than for the main metal due to application of ceramic gumboil. Use of lining materials has allowed to reduce tension of welded knot and to avoid formation of cracks during the welding. |
