Description

用于检查焊缝的方法
技术领域
本发明涉及一种借助于数据处理装置来检查塑料管道的焊缝（weld）的方法，该方法包括：
Figure DEST_PATH_IMAGE001
捕获和存储文档；
Figure DEST_PATH_IMAGE001A
监测和记录接合处的焊缝的安装和实现；
Figure DEST_PATH_IMAGE001AA
产生焊接报告；
Figure DEST_PATH_IMAGE001AAA
超声测试焊缝，其中测试检测和存储处于焊缝中的缺陷。
背景技术
从现有技术已知单独步骤，例如产生相关文档、执行焊接并且产生焊接报告以及测试焊接的接合处。但是，证明文件（documentation）和数据被单独管理，而不允许焊接的接合处的自动生成的鉴定（appraisal）。
这具有尽管并非全部的证明文件为可用时也通常批准焊接的接合处的缺点，并且还具有并非全部的数据都结合在焊接的接合处的评估中的缺点。
发明内容
本发明的目的是要提出一种方法，该方法允许对在塑料管道上现场实现的超声测试的焊接的接合处的评定，该评定从所捕获的文档和数据自动生成。
这个目的按照本发明来实现，因为软件用来捕获和存储文档、焊接报告和缺陷，更特别地捕获和存储关于所述缺陷的数据，其中软件的算法用来评估所存储的文档、报告、缺陷和数据，并且将焊接的接合处分类为符合或者不符合要求。全部记录的文档和数据提供与焊接的接合处质量有关的结论，所述结论然后能够通过算法来评估，以评定焊接的接合处是否满足要求。
按照本发明的用于检查塑料管道之间或者管件与管道之间的焊接的接合处以及使用电熔合耦合器（coupler）的焊缝的方法被执行，并且对应地借助于数据处理装置来评估。
智能电话、平板（要不然（or else）便携计算机）以及其他已知数据处理装置优选地能够用作数据处理装置。
该检查方法除了别的以外还包括为了检验其质量和可接受性的目的而对文档(优选地为材料规范、记录、协议、证书、报告、技术规范等)、与组件以及组件的焊接相关的任何文档的捕获和存储。显然，有可能相应地定义要求哪些文档等以便能够执行评估，以及可选地能够保存哪些文档。
管件和管道或者两个管道之间的焊缝的安装和实现被监测并且借助于数据处理装置适当地记录，优选地通过图像和/或视频以及来自焊接装置的焊接数据来捕获和记录。
焊接报告然后由所捕获的焊接数据来产生，其中所述焊接报告优选地通过软件自主产生，或者焊接报告通过焊接机器已经产生，并且这时被传送给数据处理机器。
作为按照本发明的方法的附加步骤，超声测试焊缝，其中测试检测和存储处于焊缝中的缺陷。
全部所收集的文档、焊接报告、数据和缺陷都保存在软件中，或者被存储，使得软件能够访问全部所收集的文档、焊接报告、数据和缺陷，以及软件的算法评估所存储的文档、报告、缺陷和数据，并且将焊接的接合处分类为符合或者不符合要求。
按照本发明的方法优选地能够适用于熔合对接（butt-fusion）焊缝和电熔合耦合器焊缝。塑料管道相应地能够相互熔合对接焊接，并且还借助于电熔合耦合器来接合。显然，其他管件也能够熔合对接焊接到管道端。
如果逐步指定并且逐步监测和记录安装，则是有利的。例如，软件例如借助于图片或附图来定义耦合器如何打算被推送到管道上，并且这借助于由软件所保存的照片来检验。优选地，焊缝的位置也通过对应坐标来捕获，由此始终有可能准确地跟踪焊缝的位置，即使它位于地下也是如此，正如铺设管线的大多数情况中通常的情况。
算法优选地包括基于待焊接组件来采用初始值。这意味着，例如，如果使用某个直径和材料的电熔合耦合器，则预定义数值由软件用作初始值。另外，值对于所检测的缺陷来计算，并且通过超声测试来存储。然后，从所采用的初始值中减去基于缺陷所计算的值，以得到被测试的焊缝的差值。将这个差值与参考值进行比较，该参考值同样对相关焊缝预先定义。参考值是基于先前破坏性长期测试的经验值，所述测试确定什么最小值必须存在以符合要求。如果差值相等或者高于参考值，则焊缝是可容许的；如果差值低于参考值，则焊缝是不容许的。
如果缺陷基于其尺寸来计算，则是有利的。这意味着，优选地，缺陷的宽度、长度和/或深度被检测并且适当地计算，以及作为对应值而结合在算法中并且从所采用初始值中扣除（deduct）。
已经证明软件采取app的形式是有利的。由此对用户施加并且指定用户必须满足的约束。例如，然后指定，强制文档、报告等打算被输入到app中，否则不批准焊接的接合处，或者通过软件的评定不是可能的。即使例如在测试之后，焊缝中没有缺陷是可检测的，并且焊缝实际被评定为良好，但是用于准许（clearance）的某些文档缺失，则情况也是这样。但是，对于app的这种设定也能够被改变并且是较少约束的。
数据优选地被收集并且例如在云或远程服务器中中央存储，并且通过软件来访问。数据经由WEB平台来访问也是有可能的。因此，数据能够不仅经由WEB平台而且还经由app或其他软件来访问。
优选地通过接收新数据来细化算法，或者系统是自学习的。
附图说明
参照附图来描述本发明的示范实施例，其中本发明并不是仅限制到示范实施例，并且其中：
图1示出按照本发明的方法的示意图以及在其中包含的文档和步骤。
具体实施方式
图1中所呈现的附图示出按照本发明的方法需要评定焊接的接合处是否可容许的全部数据和证明文件。图1示出针对该方法软件和数据处理装置捕获的几个优选文档1。显然有可能在软件中准确定义哪些文档对评定是强制性的，而哪些文档是可选的。这些文档然后被捕获和存储。存储能够在数据处理装置中并且还在外部服务器上或在云中进行。管道和/或管件的安装过程2然后例如通过图像来监测，并且记录焊缝的位置或坐标。这也再次借助于软件来输入和管理。另外，来自超声焊接的数据被捕获3，其中焊接装置将数据传送给按照本发明的方法的软件或者传送给数据处理装置，以及使用软件来产生焊接报告3，或者焊接报告3已经通过焊接机器产生并且被传送给软件。然后超声测试焊缝4，其中测试提供与焊缝中的缺陷有关的信息。在软件中保存的算法5(流程图是纯粹象征性表示)以及所捕获的数据和文档用来产生报告5，该报告5优选地基于焊接的接合处质量来指示焊缝是可容许还是不容许的。
