Description
Technical field
The utility model relates to a kind of measuring system that is used for small breach, relates in particular to a kind of drop-hammer test piece measuring system.
Background technology
As everyone knows, drop-weight test is to be used for the measurement structure steel to produce a kind of test method of brittle fracture, is one of metals such as nuclear power generating equipment, member important means of judging the bead welding performances.Single track welding bead with certain-length, width and thickness of drop-hammer test piece surface overlaying is called the fragility welding bead, and its main effect is to form a little physical rupture defective when drop-weight test in base metal test specimen.Because drop-hammer test piece representative is the material that is in final condition of heat treatment, thereby the cutting, prepare and selecting for use of surfacing welding electrode all had quite high requirement of mother metal; Except that selecting for use surfacing welding electrode should have the good welding technology, the performance index of the hardness of its overlay cladding, deposit metal tensile strength, mechanics all have strict requirement.Drop-weight test data declaration many times: the nil-ductility temperature TNDT of steel, not only relevant with the material that uses, and substantial connection is also arranged with the thickness of sample.
For general square body, cylinder, its size can select for use slide calliper rule directly to measure, and for some breach, slide calliper rule also can directly be measured.But because of when noticing, when some gap widths were very tiny, the card base of general slide calliper rule also can't go deep into breach directly to be measured, thereby can't record true value.For example, for drop-hammer test piece, its structure can be as shown in Figure 1, and it comprises mother metal 1 ' and be arranged on the bead-on-plate weld 2 ' of mother metal 1 ' upper surface that wherein, the upper surface of bead-on-plate weld 2 ' is provided with weld seam breach 3 '; Use correct overlaying process, the bottom physical property of fragility weld seam breach 3 ' fracture in the time of promptly will guaranteeing drop-weight test just must be strengthened the measurement to the distance X of mother metal 1 ' upper surface of the flatness of fragility weld seam breach 3 ' and weld seam breach 3 ' bottom; Yet, the width of weld seam breach 3 ' and have only 1.5mm and 1.8mm highly respectively according to the shape of drop-hammer test piece weld seam breach 3 ' and the requirement of required measurement data, is selected for use existing measurement instrument to measure then and can't be detected, true value can't be obtained, also measurement data can't be obtained; If can't measure this weld seam breach 3 ' and weld seam breach 3 ' the bottom distance X to mother metal 1 ' upper surface accurately, that just can't calculate the actual value of drop-hammer test piece at all accurately; An approximate value bigger than normal or less than normal all will directly influence the metal collection of illustrative plates of drop-hammer test piece and the test findings of mechanical property; Thereby, just can not be analyzed and researched to the micro-crack, the stomata sensitivity that occur in the bead-on-plate weld 2 '; To the not enough reason that produces such as deposit metal plasticity, just can not in addition correct comparison affirmation.These cause-effect relationshiies all will directly influence the physics error at measurment of drop-weight test.Be used for reality as the physics error at measurment with erroneous judgement, this will cause great nuclear safety accident.
The utility model content
