金属材料的焊接工艺规程及认证标准(EN288)与焊工考试标准(EN287)一样,是欧洲标准组织委员会(CEN)最早制定的焊接标准之一.该系列标准规定了焊接过程的基本控制,包括两个基本部分:①应用WPS的焊接工艺规程;②对于不同组别的材料和不同的应用,提供了几种焊接工艺试验方法.这样,就可以确保在限定的应用领域内使用合格的焊接工艺.另外,EN288作为欧洲最早的焊接标准,在使用中也遇到了一些问题,由于 The Welding Procedure Specification and Certification Standard for Metallic Materials (EN288), like the Welder Examination Standard (EN 287), is one of the earliest CEN welding standards developed by the European Organization for Standardization (CEN), which sets the basic controls for the welding process including two A basic part: ① application of WPS welding process procedures; ② for different groups of materials and different applications, provides several welding test methods, so that you can ensure that the limited application areas using qualified welding process. In addition, EN288 as Europe’s earliest welding standards, in use also encountered some problems, due to
