GOST 7122-81

ГОСТ 7122-81

Weld seams and all-weld metal. Methods of sample selection for determination of chemical composition

Швы сварные и металл наплавленный. Методы отбора проб для определения химического состава

Status: Effective. The limitation of effectiveness has been lifted: Resolution of the State Standard No. 1417 of 09/03/91

The standard establishes sampling methods for determining the average, layer-by-layer and roll-on chemical composition of welds or weld metal obtained by fusion welding of single-layer and multi-layer metallic materials and alloys with uniform and dissimilar welding materials. The standard does not apply to welds made without the use of filler metal by diffusion, contact welding, friction welding, etc.

Стандарт устанавливает методы отбора проб для определения среднего, послойного и поваликового химического состава сварных швов или наплавленного металла, полученных сваркой плавлением однослойных и многослойных металлических материалов и сплавов однородными и разнородными сварочными материалами. Стандарт не распространяется на сварные швы, выполненные без применения присадочного металла диффузионной, контактной сваркой, сваркой трением и т. п.
