Abstract
Изобретение относится к сварочному производству и может найти применение в разных отраслях промышленности при изготовлении сварных конструкций из закаленных сталей. Способ крепления прихваточным швом деталей из закаленных сталей заключается в прерывистой дуговой сварке коротких временных швов длиной, во много раз меньше промежутков между ними, с дуговыми нагревами их во время и/или после охлаждения, преимущественно вне этих коротких швов. Такие нагревы выполняют, дополнительно сваривая короткие швы на участках, прилегающих к ним, преимущественно без повторного расплавления. Достигается повышение трещиностойкости прихваточного шва и надежности крепления закаленных сталей сваркой прихваточного шва перед сваркой основного шва.
