Please help translate the following text regarding the manufacturing method of production test plates (PTPS)
Thread Content
PTPs for longitudinal welds are to be produced as a direct extension of one of the welds within the coverage, whereas PTPs covering circumferential welds must be made in parallel with one of the welds by the same operator(s), using the same equipment and process parameters.
It’s really a matter of different fields – are PTPs process/production testing plates? It seems to refer to two scenarios: one vertical and the other tangential. Vertical test plates need to be extensions of the material being tested, while tangential test plates require parallel samples under identical conditions (personnel, equipment, parameter settings). . What I don’t understand are: the purpose of PTP, the meaning of coverage, and whether \"weld\" refers to a welded part or a weld seam.
Is a test board a type of circuit board? If that’s the case, \"weld\" can be translated as the circuit welded onto it.

It is speculated that the original poster is not very familiar with pressure vessels and the relevant standards in the United States. These are the provisions in the ASME standards regarding the inspection procedures for pressure vessel equipment. PTP: Welding of \"product inspection test samples\", which are to be delivered to the customer for inspection. Longitudinal welds: Welds that are straight in shape. Circumferential welds: Welds that form a circle, such as those on the lids of pressure vessels. This test sample must be prepared by the same welder who welded the container, using the same welding equipment and the same welding parameters (current, voltage, welding rod, etc.). In this way, completing the translation isn’t difficult.
