浅谈对WPS和PQR的理解和分析技术质量部伍磊摘要:焊接工艺评定报告(英文缩写PQR,取自英文焊接工艺评定报告Welding procedure qualification record)中后三词的词头,70年代自国外引进以来,已是压力容器、压力管道制造、安装、修理中必不可少的工作程序,是评定制造、安装、修理单位焊接技术水平(资格)的依据。
由于其科学、合理、严格的评定过程,也被钢结构、贮罐制造和安装等行业采用。
虽然叫法有些不同(有的叫焊接工艺试验),但方法和要求是基本一致的。
焊接工艺规程(英文缩写WPS取自英文Welding procedure specification的词头)50年代自苏联引进。
改革开放以来,引进西方的WPS经过多年消化、创新,目前我国焊接生产、工程安装中已广泛编制WPS用于指导生产。
WPS与PQR的关系,前者是后者的编制依据。
关键词:焊接工艺评定报告;焊接工艺规程;材料;焊接;试验0、前言在压力管道、船舶等产品的制造中,经常会遇到两种形式的焊接文件,即焊接工艺文件(WPS)和焊接工艺评定报告(PQR)。
在一个工程开工之前,监理和业主往往要求制造商出示此类文件。
然而很多厂家和部门常常为其所困,采用模糊、拖延的方法来应付,也有的部门说不清对方到底需要的是什么资料,使生产和经营处于非常被动的地位。
国内外焊接制造规范都要求企业进行焊接工艺评定,以验证企业焊制符合标准接头的基本能力(最低门槛指标) 。
一般情况下,焊接工艺评定由企业的技术部门编制,根据产品需求,按照有关标准如美国的ASME 第Ⅸ篇、欧洲EN 288—3及我国的JB 4708-2000等标准执行.遵照标准每种重要参数的改变,如焊接方法、母材类别(组号)、预热温度、热处理温度、焊接热输入超出规定的范围,都要进行焊接工艺评定试验。
由于影响焊接接头力学性能的工艺参数众多,很多企业都积累了大量的焊接工艺评定报告。
中海金洲一直致力于研究有效利用和管理焊接工艺文件及焊接工艺评定报告的方法,以此来提高公司产品的焊接质量及生产效率,降低生产成本,从而大幅度提高企业的经济效益。

This is in respect of specific types of products and if, forexample, a works requests approval for both plates and sections or bars, it will benecessary to carry out tests on two casts rolled into plates and two different castsrolled into sections or bars.3.2.2 Subsequently, and at works where an extension of approval is requested to coveradditional steel grades, only one cast for each type of product need be submitted for tests.approval3.2.3 The dimensions of the products from each cast submitted for approval tests are to berepresentative of the range which will be manufactured and should include at least one batch of material of the maximum thickness and width or diameter which it is proposed to supply, i.e. material where the amount of hot working is at the minimum valueproposed by the manufacturer.3.2.4 With the exception of hot coiled strip, approval tests are to be carried out on two rolledproducts of different thickness or diameter from each cast. For plate, wherever possible these tests are to be carried out on one plate 12 mm to 20 mm thick and on another ofthe maximum thickness that will be produced. For ingot cast material, one plate is to be representative of the top of the first ingot and the other is to be representative of the last ingot from the ladle. Similarly for continuous casting, one plate is to be representative of the beginning of the cast and the other of material poured when the ladle is nearlyempty.3.2.5 For hot coiled strip, materials for approval are to be taken from two coils (as defined in3.1.1 and 3.1.2) selected from different casts. The coils selected are to berepresentative of material from an ingot top end and an ingot bottom end or, in the case of continuously cast material, from the beginning of one cast and from the end of theother. Additionally one coil should be of the maximum thickness that it is proposed tosupply.3.3 Specific product approval information3.3.1 For each cast submitted for approval tests, the steelmaker is to provide the followinginformation:(a) Ladle analysis including residualelements, aluminium (either total orA B CDacid soluble), other grain refiningelements (niobium, titanium andvanadium), where applicable, nitrogenand calculated carbon equivalent value.For steel made by a bottom blownoxygen process, the hydrogen contentis to be stated.(b) Dimensions of ingots, method ofcasting and discards during rolling.

通常通过对于船舶监造和定期检查来确保航海设备满⾜其规范。
责任船级社设定技术规范,确认船舶和其他航海设备设计满⾜规范要求。
在船舶建造和调试期间进⾏监控,并在设备和船舶运营期内进⾏持续检查以确保船舶和设施持续符合规范要求。
船级社同样对于⽯油平台,离岸设施和潜艇进⾏船检。
船检过程涉及的柴油发动机,重要的舰载泵和其他重要机械。
验船师进⾏船检以确保该船舶,其设备和机械建造以及维护符合其⼊级船级社的规范要求。
历史⼗⼋世纪中,伦敦的商⼈,船东和船长经常聚集在爱德华劳埃德(Edward Lloyds)咖啡馆谈论⼋卦,分享航⾏见闻已经从事交易。
⼤部分的船舶和货物保险都在此地办理。
不久,保险业就意识到需要对于船舶的质量进⾏了解。
在1760年注册协会成⽴,发展成世界上第⼀个船级社劳⽒船级社,并开始对船舶开始检验和登记⼊级,并开始对于船舶和设备进⾏分类。
当时将船体技术状况划分为五类:A(最好)、E(较好)、I(中等)、O(较坏)、U(最坏);⼜将所帆、锚等设备分为三类:G(好)、 M(中)、B(坏)。
随着时间的推移,G、M和B被1,2,3所替代。
这也是现在众所周知的代表最⾼等级的 A1的由来。
该系统的⽬的是,对船舶安全性,适航性的风险评估。
劳⽒船级社在1764年出版了第⼀版船舶登记簿,并在1764年到1766年间使⽤。
必维船级社(Bureau Veritas)与1828年在安特卫普成⽴,并与1832年搬迁到巴黎。

The society will also validate that construction is according to these standards and carry out regular surveys in service to ensure compliance with the standards.ResponsibilityClassification societies set technical rules, confirm that designs and calculations meet these rules, survey ships and structures during the process of construction and commissioning, and periodically survey vessels to ensure that they continue to meet the rules. Classification societies are also responsible for classing oil platform, other offshore structures, and submarines. This survey process covers diesel engines, important shipboard pumps and other vital machinery. Classification surveyors inspect ships to make sure that the ship, its components and machinery are built and maintained according to the standards required for their class.HistoryIn the second half of the 18th century, London merchants, ship-owners, and captains often gathered at Edward Llord coffee house to gossip and make deals including sharing the risks and rewards of individual voyages. This became known as underwriting after the practice of signing one's name to the bottom of a document pledging to make good a portion of the losses if the ship didn’t make it in return for a portion of the profits. It did not take long to realize that the underwriters needed a way of assessing the quality of the ships that they were being asked to insure. In 1760, the Register Society was formed —the first classification society and which would subsequently become Llord's Register — to publish an annual register of ships. This publication attempted to classify the condition of the ship’s hull and equipment. At that time, an attempt was made to classify the condition of each ship on an annual basis. The condition of the hull was classified A, E, I, O or U, according to the state of its construction and its adjudged continuing soundness (or lack thereof). Equipment was G, M, or B: simply, good, middling or bad. In time, G, M and B were replaced by 1, 2 and 3, which is the origin of the well-known expression 'A1', meaning 'first or highest class'. The purpose of this system was not to assess safety, fitness for purpose or seaworthiness of the ship. It was to evaluate risk.Samuel Plimsoll pointed out the obvious downside of insurance:The ability of ship-owners to insure themselves against the risks they take not only with their property, but with other peoples’lives, is itself the greatest threat to the safe operation of ships.The first edition of the Register of Ships was published by Lloyd's Register in 1764 and was for use in the years 1764 to 1766.Bureau Veritas (BV) was founded in Anwert in 1828, moving to Paris in 1832. Lloyd's Register reconstituted in 1834 to become 'Lloyd's Register of British and Foreign Shipping'. Where previously surveys had been undertaken by retired sea captains, from this time surveyors started to be employed and Lloyd's Register formed a General Committee for the running of the Society and for the Rules regarding ship construction and maintenance, which began to be published from this time.In 1834, the Register Society published the first Rules for the survey and classification of vessels, and changed its name to Lloyds Register of Shipping. A full time bureaucracy of surveyors (inspectors) and support people was put in place. Similar developments were taking place in the other major maritime nations.Adoption of common rules for ship construction by Norwegian insurance societies in the late 1850s led to the establishment of Det Norske veritas (DNV) in 1864. Then after RINA was founded in Genoa, Italy in 1861 under the name Registro Italiano, to meet the needs of Italian maritime operators. Six years later Germanischer Lloyd (GL) was formed in 1867 and Nippon Kaiji Kyokai (ClassNK) in 1899. The Russian Maritime Register of Shipping (RS) was an early offshoot of the River Register of 1913.As the classification profession evolved, the practice of assigning different classifications has been superseded, with some exceptions. Today a ship either meets the relevant class society’s rules or it does not. As a consequence it is either 'in' or'out' of 'class'. Classification societies do not issue statements or certifications that a vessel is 'fit to sail' or 'unfit to sail', merely that the vessel is in compliance with the required codes. This is in part related to legal liability of the classification society.However, each of the classification societies has developed a series of notations that may be granted to a vessel to indicate that it is in compliance with some additional criteria that may be either specific to that vessel type or that are in excess of the standard classification requirements. See Ice class as an example.。

该规范旨在加强对无损检测人员的管理,提高无损检测人员的专业素质,确保无损检测工作的质量和安全。
二、中国船级社无损检测人员资格鉴定与认证规范的制定目的和适用范围中国船级社无损检测人员资格鉴定与认证规范的制定目的是为了规范无损检测人员的资格鉴定和认证工作,确保无损检测人员具备必要的专业知识和技能。
该规范适用于在中国境内从事船舶、海洋工程、钢结构等领域无损检测工作的人员。
同时,对于从事这些领域无损检测工作的企业,也需要按照该规范的要求进行无损检测人员的资格鉴定和认证。
三、中国船级社无损检测人员资格鉴定与认证规范的主要内容中国船级社无损检测人员资格鉴定与认证规范主要包括以下内容:1.无损检测人员的分类和级别。
根据无损检测人员的技能水平和专业能力,将无损检测人员分为不同的级别,包括初级、中级、高级等。
2.无损检测人员的资格鉴定和认证程序。
包括报名、考试、实习、评审等环节,以及对应的资格证书和认证标志。

四、中国船级社无损检测人员资格认证委员会的组织与职责中国船级社无损检测人员资格认证委员会是负责无损检测人员资格鉴定和认证工作的专门机构。
其主要职责包括:1.制定和修改无损检测人员资格鉴定和认证规范。
2.组织实施无损检测人员资格鉴定和认证工作。
1.要先做PWPS。
也就是预WPS,这个要根据自己的需要设计。
我们一般都是总结出来需要的板厚、材质、坡口、焊接方法以后,找以前别人做过的WPS作为参考,由此生成PWPS,交由船检审核签字。
2.船检认可PWPS后,要请船检确认钢板的厚度、材质,同时提供钢板证书,以便船检核对钢印号。
确认完毕后船检敲钢印。
3.加工试板,这个一般都有专业人员加工了。
不同的船级社要求试板尺寸不太一样,事先查好规范就行了。
不过一般专业的验船师也不会太计较,只要够切实验试块儿就可以了。
4.焊接。
有焊工证的资深焊工,按照PWPS的设计进行焊接,不过也不能完全照搬,焊工的经验蛮重要的。
此时要提供焊工的焊工证,身份证,焊材证书,最好还有焊机的校验证书。
同时记录所有实验数据,结束后请验船师签字。
此过程一般验船师都要在旁边观察的。
试板焊接结束后,验船师要检查外观,然后敲钢印。
钢印一定要清楚密集,保证接下来加工成试块以后,每块试块上都有钢印。
5.接下来是做无损检测了。
一般都要求做RT和MT,做完后探伤机构出具合格的探伤报告就可以了。
将探伤报告给验船师审核签字。
6.无损检测合格后,将试板按照相应船级社的规范加工成若干试块(查阅相关船级社规范的材料与焊接部分,然后与验船师沟通确认),以进行接下来的机械性能试验。
7.机械性能试验。
验船师在场,在专业的理化实验室进行,不用操心,等着出报告就是了。
8.合格的机械性能试验报告拿到以后,交验船师审核签字。
9.以上实验部分已经完成,接下来准备相关文件了。
根据各种数据生成WPS和PQR(尽量把所有信息集中在一页之内),交船检签字盖章就OK了。
至于WPS和PQR的样式,每个船级社不尽相同,实在找不到,向船检要好了。
10。
最后把之前所有的文件整理好,生成目录存档保存,就是一份完整的WPS了。
我们公司的WPS包括:1.目录2.PWPS3.PQR4.焊接试验记录表5.无损检测报告(RT/MT)6.机械性能试验报告(宏观,硬度,弯曲,拉伸,冲击)7.钢板证书9.焊材证书10.焊工证复印件以上是我个人做焊评的一点儿经验。
