各省、自治区、直辖市劳动(劳动人事)厅(局): 压力容器制造单位反映,在确定某些压力容器产品焊接试板数量时,由于对规程、标准理解不一,遇到一些问题,如:压力容器环焊缝是否要制备焊接试板;只有环焊缝没有纵焊缝的压力容器是否要制备焊接试板;由不同钢号或不同板厚范围组成的一台产品,或有不同热处理要求的一台产品应制备几块产品焊接试板等。为此,经有关单位研究,关于压力容器产品焊接试板除必须遵守
Labor Bureau (Bureau): The pressure vessel manufacturing units reflect that when it comes to determining the number of welding test plates for some pressure vessel products, due to different understandings of procedures and standards, some problems have been encountered, such as: Whether the pressure vessel girth weld preparation of welding test panels; only girth welds without longitudinal weld pressure vessel whether to prepare welding test panels; by a different steel or different thickness range of a product, or have different heat treatment requirements A product should be prepared a few pieces of product welding test panels. To this end, the relevant units of research, on the pressure vessel welding products in addition to test panels must comply with
