中文名称: 焊件接触式超声波检测规程 | 英文名称:Standard Practice for Contact Ultrasonic Testing of Weldments |
中标分类:J33 | ICS分类:25.160.40 | 标准分类编号:AS | 页数:24 |
发布日期: | 实施日期:2008-07-01 | 作废日期: | 被替代标准: | 代替标准:ASTM E164-2003 | 引用标准: | 采用标准: | 起草单位: | 归口单位: |
标引依据: | 补充修订: | 备注: | 范围:1.1 This practice covers techniques for the ultrasonic A-scan examination of specific weld configurations joining wrought ferrous or aluminum alloy materials to detect weld discontinuities (Note 1). The reflection method using pulsed waves is specified. Manual techniques are described employing contact of the search unit through a couplant film or water column. 1.2 This practice utilizes angle beams or straight beams, or both, depending upon the specific weld configurations. Practices for special geometries such as fillet welds and spot welds are not included. The practice is intended to be used on thicknesses of 0.250 to 8 in. (6.4 to 203 mm). Note 1—This practice is based on experience with ferrous and aluminum alloys. Other metallic materials can be examined using this practice provided reference standards can be developed that demonstrate that the particular material and weld can be successfully penetrated by an ultrasonic beam. Note 2—For additional pertinent inf
