Abstract
1. Способ исправления дефектов металлоконструкций, включающий механическую разделку дефектного места, установку в нее вставки из сплава, близкого по химическому составу с основным металлом, локальный нагрев и заполнение разделки расплавленным металлом вставки, отличающийся тем, что вставку, соответствующую по форме и размерам разделке, плотно вставляют в указанную разделку, а затем осуществляют локальный нагрев методом контактной точечной сварки с перекрытием литым ядром границы между поверхностями вставки и основного металла, причем образующая контактной поверхности между вставкой и основным металлом совпадает с направлением сварочного тока.2. Способ по п.1, отличающийся тем, что увеличивают площадь сплавления вставки и основного металла, используя технологические накладки в процессе контактной точечной сварки.1. A method for correcting defects in metal structures, including mechanical cutting of a defective place, installation of an insert of an alloy of a similar chemical composition to the base metal, local heating and filling of the cutting with molten metal of the insert, characterized in that the insert is suitable in shape and size for cutting, tightly inserted into the specified grooves, and then carry out local heating by the method of contact spot welding with overlapping cast core the boundary between the surfaces of the insert and the base metal, and forming the contact surface between the insert and the base metal coincides with the direction of the welding current. 2. The method according to claim 1, characterized in that the fusion area of the insert and the base metal is increased using technological overlays in the process of contact spot welding.
