**Coursera welding course summary:** This Coursera course focuses on preparing candidates for the American Welding Society (AWS) Certified Welding Inspector (CWI) exam, specifically Part B (Practical) and Part C (Code Book Applications), with a strong emphasis on key welding processes. **Key Learning Areas:** * **Welding Processes:** Comprehensive understanding and practical knowledge of Submerged Arc Welding (SAW), Gas Metal Arc Welding (GMAW), Flux-Cored Arc Welding (FCAW), Electroslag Welding (ESW), and others like PAW, RW, SMAW, GTAW, etc. This includes details on power sources, welding guns, wire feeding, electrode selection, flux types, transfer modes (GMAW), and specific applications. * **Non-Destructive Testing (NDT):** Fundamental principles of Visual Testing (VT), Magnetic Particle Testing (MT), Ultrasonic Testing (UT), Penetrant Testing (PT), Radiographic Testing (RT), and Leak Testing (LT). * **Quality Assurance:** Knowledge of quality procedures, audits, and surveillance. * **Welding Metallurgy:** Understanding the fundamental principles of welding metallurgy. * **Technical Documentation:** Familiarity with welding symbols, engineering drawings, report preparation, and compliance verification of base material, filler metal, documentation, procedure qualification records, and NDE procedures. * **Safety:** Applicable safety requirements in the workplace as per international standards. **Exam Preparation:** The course aims to equip learners with the skills and knowledge required to pass the CWI exam, where a minimum of 72% is required for each part (A, B, and C). It emphasizes studying AWS documents like QC1:2016-AMD1 and B5.1:2013-AMD1 for thorough preparation. **Upon Completion:** Learners will gain the skills of a Certified Welding Inspector and a comprehensive understanding of the covered welding processes and inspection techniques.
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 and 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.After completing the course learners can achieve the full knowledge of the following subjects:The skills of a Certified Welding Inspector of the American Welding Society.Submerge Arc Welding (SAW) Power Sources.
