**课程名称：** 焊接工艺与焊接检验员（CWI）培训 - 第一部分：SMAW/PAW/GTAW **课程概述：** 本课程是针对焊接检验员（CWI）认证考试的第一部分，专注于焊接基础知识。CWI 考试共分三个部分： * **A 部分：基础知识** - 闭卷考试，涵盖 150 道题目，内容包括焊接基础、术语与定义、焊接工艺、无损检测、焊接规程、焊接符号、计算、安全实践以及 CWI 的职责。 * **B 部分：实践操作** - 动手实践测试，评估学员通过目视识别焊接缺陷并判断焊缝是否合格的能力。 * **C 部分：焊接规程应用** - 开卷考试，旨在考察学员对特定焊接规程的熟悉程度和应用能力。 **考试通过标准：** A、B、C 三部分均需达到 72% 的合格分数。 **课程内容：** 本课程将使学员掌握以下关键知识和技能： * **报告的准备** * **全面的焊接工艺知识：** * SAW (埋弧焊) * PAW (等离子弧焊) * RW (电阻焊) * SMAW (手弧焊) * SW (埋弧焊，与 SAW 可能重复或指代不同变种，此处按原文列出) * FCAW (药芯焊丝电弧焊) * GTAW (钨极惰弧焊) * OFW (氧乙炔焊) * ESW (药芯焊丝电弧焊，可能与 FCAW 重复或指代不同变种，此处按原文列出) * GMAW (气体保护金属电弧焊) * **热喷涂** * **机械切割** * **热切割/坡口** * **钎焊/钎焊焊** * **基本无损检测（NDT）原理：** * VT (目视检测) * MT (磁粉检测) * UT (超声波检测) * PT (渗透检测) * RT (射线检测) * LT (泄漏检测) * **质量程序知识** * **质量审核/监督** * **焊接冶金基础知识** * **所有焊接符号和工程图纸的知识** * **母材合规性** * **焊材合规性** * **焊材的储存与处理** * **检验记录的合规性** * **正确文件的核实与合规性** * **母材与焊材的兼容性** * **文件的认证结果与合规性** * **工艺评定记录的合规性** * **焊接规程的合规性** * **NDE 规程的合规性** * **符合国际标准的适用工作场所安全要求** **重要参考资料：** 建议学员参考 AWS 网站提供的免费文档，以充分准备考试： * QC1:2016-AMD1 - 焊接检验员 AWS 认证规范 * B5.1:2013-AMD1 - 焊接检验员资质规范 （请仔细研读上述文档，为回答相关问题做好充分准备。）
The CWI exam consists of three partsPart A - FundamentalsPart B - Practical,Part C - Code Book Applications.Part A is a closed-book exam that consists of 150 questions on the welding fundamentals, terms and definitions, welding processes, nondestructive examination, procedures, symbols, calculations, safety practices, and duties and responsibilities of a CWI.Part B is a practical hands-on test to find the ability to visually identify welding discontinuities and to determine the acceptance or rejection of a weld.Part C is an open book test of Code application to evaluate the applicant's familiarity and ability with a selected code application.The pass marks for Part- A, B & C is 72%You can refer to the full details of AWS Certification and Qualification Standards in the following documents available at free of cost on the AWS website:QC1:2016-AMD1 - Specification for AWS Certification of Welding InspectorsB5.1:2013-AMD1 - Specification for the Qualification of Welding Inspectors(Study the documents and be prepared well to answer any question from the document.)In this course the candidate will learn the following :Preparation of reportsComplete knowledge and understanding of the following welding processes:SAW - PAW - RW - SMAW - SW- FCAW- GTAW -OFW- ESW- GMAW.Thermal Spraying SolderingMechanical Cutting Thermal Cutting/GougingBrazing/Braze WeldingThe fundamental principles of the following ND Tests:VT, MT, UT, PT, RT, LTHe will acquire knowledge of quality procedures Quality audits/surveillance.Knowledge and understanding of the fundamentals of welding metallurgyKnowledge and understanding of all the welding symbols and engineering drawings.Base material complianceFiller metal complianceFiller metal storage, handlingInspection records complianceVerification of proper documentation complianceBase material and filler metal compatibilityCertification of documented results and complianceProcedure qualification records complianceWelding procedure complianceNDE procedures complianceApplicable safety requirements in the workplace as per the International Standards
