摘要：

In making weld joints the necessity arises of heat treatment of weld joints to improve the structure in the metal and relieve stresses occurring in welding. Such a heat treatment is normally done in special furnaces requiring large power expenditures. This work experimentally showed the possibility of using for this purpose pyrothermal treatment of a weld joint by a flexible thermochemical strip. Such a heat treatment of weld joints is especially effective in laying of main line pipe and construction of metal structures under field conditions.
