какую нагрузку выдержит сварной шов

Таблицы несущей способности угловых швов

Таблицы несущей способности сварных швов составлены на основании НиТУ 121-55 при расчете конструкций по предельному состоянию. Расчетные сопротивления швов приняты как произведения нормативных сопротивлений на соответствующие коэфициенты однородности (с округлениями ) в соответствии с табл. 12 (13) НИТУ 121-55

Таблицы составлены для угловых (валиковых) швов (лобовых, фланговых и втавр) Работающих на напряженное состояние сжатия растяжение и среза.

Таблицы составлены на 6 случаев сочетания марок стали со сваркой определенными электродами в соответствии с табл. 12(13) НИТУ 121-55

Сварные швы рассчитаны по формуле на сжатие, растяжение и срез угловых швов.
