GB/T 35085-2018 Destructive tests on welds in metallic materials—Vickers and Knoop Hardness testing of joints welded by laser and electron beam
Abstract
This standard specifies the Vickers and Knoop hardness tests for the cross-section of narrow welds in metal materials by laser and electron beam. The Vickers hardness test force range specified in this standard is typically 0.098 N to ≤98 N (HV 0.01 to ≤HV 10), and the Knoop hardness test force range is typically no more than 9.8 N (HK 1). This standard applies to hardness tests on weld samples with or without filler wire. This standard does not apply to hardness tests on samples with laser/arc composite wide welds. Hardness tests on non-narrow welds shall be conducted in accordance with GB/T 2654 and GB/T 27552.
