**课程概述：WPS与PQR的理解与准备** 本课程深入探讨了焊接领域一个重要且专业的议题——焊接工艺规程 (WPS) 和焊接工艺评定 (PQR)。课程首先明确了 WPS 和 PQR 的定义，阐述了它们在工业项目中的作用和重要性。 课程区分了预置工艺规程 (pWPS)、WPS 和 PQR，并解释了为何需要这些规范。此外，课程详细介绍了焊接变量，包括其含义、在制定 WPS 中的重要性，并将其分为三大类：**必须变量 (essential variables)、非必须变量 (non-essential variables) 和补充变量 (supplementary variables)**。课程将逐一讲解这些变量的定义及其对 WPS 制定的影响。 课程的学习路径清晰地勾勒出焊接工艺评定的主要步骤：首先理解 WPS 的预期应用场景，随后制定**预置工艺规程 (pWPS)**，接着进行 1G、2G（立焊）、3G（横焊）、4G（仰焊）等模式的**工艺评定焊**，最后对评定焊进行**测试**并撰写 WPS。 在课程的最后一个阶段，我们将重点讲解 **PQR**。内容包括 PQR 的制定目标、准备方法，以及应用于 PQR 的各种**力学性能测试**和相应的**验收标准**。为了加深理解，课程还将提供一个实际的 WPS 范例，其中包含了我们所学的各种焊接变量及其使用范围，以及包含力学测试和验收标准的 PQR。
The course is one of the interesting & specialist topic in welding. The course shed light on the definition of WPS & PQR, which lead to the aim of them and influence of industrial projects. On the other hand, the course offered the different between pWPS, WPS & PQR and why we should go through these expressions.In addition, the course exposed to the welding variables, what do they mean? What are their important in formulating the WPS? Welding variables are classified into three categories; essential, non-essential and supplementary variables so the course explains their definitions and their effect on the establishment of WPS. The course draw main rules to qualify a welding process starting with understand the intended application for which the WPS will be used and develop a draft procedure (Called Preliminarily WPS "pWPS" ( after that make a qualification weld and finally test the qualification weld and write up the WPSThe last step in our course is PQR, what is the aim of PQR, how can it prepare? what are the mechanical tests applied on it and what is the acceptance criteria for each test. In addition, we offered an approved example of WPS for more strong understanding. In this example we show all welding variables which we studied in the course with their ranges and also the PQR with its mechanical tests with acceptance criteria
