1. 目的 Intent
本工艺是根据LR规范及IACS焊接质量和无损探伤检测指南要求制定的焊缝渗透检测质量控制程序。
The workmanship is bad on the quality control procedure of am penetrate testing of the rule of LR and IACS guideline of welding quality and NDT of ship steel welds.
2. 适用范围 Scope
本工艺适用于所有铁质材料和非铁质材料(非多孔性)表面开口缺陷的检测。
This standard applies to all ferrous and nonferrous materials (non-porosity) for detecting open flaw on the surface.
3. 职责 Obligation
3.1 参照程序 The standards cited in this Standard are as follows:
(a) LR 新建船入级及建造规范
(b) EN ISO5817(2003)
(c) 船舶钢焊缝渗透检测工艺和质量分级 CB3958-2004
(d) IACS Guideline Non-destructive testing of ship hull steel welds
3.2合格标准 Acceptance criteria
(a) LR船舶入级规范和规则
(a) LR steel a going ship classification and building rule
(b)IACS焊接质量和无损探伤检测指南
(b) IACS Guideline Non-destructive testing of ship hull steel welds
4. 检测时机 Test time
4.1 渗透检测安排在焊缝冷却至环境温度并且在采用焊后热处理之后进行。
Test shall be arranged until welding am is cooled down to environmental temperature and after welding heat treatment is executed.
4.2 对有延迟裂纹倾向的焊缝或材料应在焊后24(强度大于400MPa或碳当量大于0.41的钢应在焊后48小时)小时以后进行。
Test shall be proceeded in 24(steel that бs>400MPa or Cev>0.41 should be 48) hours after welding for the welding ams or material intended to delayed crack.
5. 检测人员 Inspector
5.1 从事渗透检测人员应具有必要的专业知识,并经过技术培训,必须持有中国船级社或有关部门颁发的并与其工作相适应等级的无损检测技术资格证书,在有效期范围内。
The inspectors who perform the test shall have the required qualification or sufficient knowledge, skill, and experience equal to that of the qualified engineer and shall hold non destructive testing qualified certificate issued by CCS or relative authorities, it should be in valid time.
无损检测人员应取得按有关规程或技术条件的规定严格的培训和考核,并持有国家有关部门(CCS等)颁发的并与其工作相适应的等级资格证书。进行检测的人员应当根据国家公认的认证计划或按照等同于ISO 9712, SNT-TC-1A, EN473或ASNT ACCP 进行二级资格鉴定和认证。一级资质的操作人员可以二级或三级资质人员的管理下进行测试。
获得国家公认的认证计划或按照等同于ISO 9712, SNT-TC-1A, EN473或ASNT ACCP 认证的三级资质人员有责任准备和认可无损探伤操作程序。
Operators should be qualified according to a nationally recognid scheme with a grade equivalent to level II qualification of ISO 9712, SNT-TC-1A, EN 473 or ASNT Central Certification Program (ACCP). Operators qualified to level I may be engaged in the tests under the supervision of personnel qualified to level II or III.
Personnel responsible for the preparation and approval of NDT procedures should be qualified according to a nationally recognid scheme with a grade equivalent to level III qualification of ISO 9712, SNT-TC-1A, EN 473 or ASNT Central Certification Program (ACCP).
5.2 检测人员的视力应每年检查一次,矫正视力不低于1.0,无色盲和色弱。 The inspectors shall test eyesight annually. Their corrected vision shall not less than 1.0, no achromatopsia or color weakness.
6. 检测材料 inspection material
6.1 探伤剂包括渗透剂(着色)、清洗剂、显像剂。应具有足够的缺陷检测能力,对被检
件无腐蚀作用、对人体无害。 Test agent includes penetrant (dyeing), rin and obrvation. It should be sufficiently able to detect the flaws.
6.2 对奥氏体不锈钢制件检测时,每种探伤剂的氯和氟含量之和不得大于1%。 Testing the austenitic stainless steel elements, the content of chlorine and fluorine shall not more than 1% for each type of test agent.
6.3 探伤剂应配套使用,不同厂家、不同型号的探伤剂不能混用。 Test agent shall be applied according to the specified and shall not mixed with other types or other maker’s.
6.4 探伤剂应放在温度为10℃~50℃的暗处保存,并应避免阳光照射。 Test agent shall be kept in shadow place at temperature between 10℃~50℃ and to avoid from sunshine.
