CWI Part A - Part 2 ( Clause 1 to 4)

AWS CWI Part A - Module 1  

Welding Inspection and Certification  

Module 1 (Chapter 1) - Part 2

 

An important aspect of the welding inspector's job is that of communication. 

  • An effective communication is often the key to avoid errors
  • The inspector should be able to express thoughts to others and be ready to listen to a reply. 
  • To be effective, this communication sequence must be a continuous loop so that both parties have an opportunity to express their thoughts or interpretations as shown in the figure.

 

Let us study The Welding Inspector Must Communicate With Various Groups

  • The welding inspector has to communicate with several different people involved in the fabrication sequence  as shown in figure
  • The communication between the welder and inspector is important to the attainment of quality work.
  • If there is Welders can discuss problems they encounter, or ask about specific requirements. 


Let us study NDE Personnel

The welding inspector must have the knowledge of

Knowledge of NDE methods, he should have a clear understanding of Nondestructive examination methods to perform his tasks.

Knowledge of NDE certification, ASNT & AWS.
There are several programs presently available to determine whether an individual possesses the necessary experience and knowledge to perform welding inspection effectively. The American Society for Nondestructive Testing has issued guidelines for certification of NDE personnel in ASNT SNT-TC-1A. ASNT recognizes three levels of certification: Levels I, II, and III.
 

AWS has also initiated an NDE Certification Program. 
There are three levels of certification in AWS QC1. 
The Senior Certified Welding Inspector (SCWI) is a person with at least 15 years of experience, including 6 years of experience while certified as a Certified Welding Inspector (CWI).
The next certification level is the CWI and the third level is the Certified Associate Welding Inspector (CAWI). Both of these certifications are covered in this course. 

 

The American Society for Nondestructive  Testing has issued guidelines for certification of NDE personnel in ASNT SNT-TC-1A.

This document describes the recommended procedures for certifying inspectors performing nondestructive testing.

Let us study AWS CWI & NDE Certification

▪          Available Through AWS

▪          SCWI, CWI, CAWI

▪          PT, MT, UT, RI

▪          Contact Certification Department

 

AWS CWI & NDE certification

  • The first step toward certification is the documentation of relevant education and work experience.
  • To qualify for the Certified Welding Inspector (CWI) examination, the individual must document his or her educational background.
  • In addition, the candidate's years of welding-related experience according to some code or specification must be documented. 
  • AWS has also initiated an NDE Certification Program. Presently, AWS can certify one Level of Radiographic Interpreter (RI). 
  • For visual inspection of welds, AWS has developed the Certified Welding Inspector program.

(SCWI) is Senior Certified Welding Inspector. 

(CWI) is Certified Welding Inspector.

(CAWI) is Certified Associate Welding Inspector. 

 

AWS QC1 is  the Standard for AWS Certification of Welding Inspectors as shown in figure

AWS QC1 describes how personal are qualified and certified, lists the principles of conduct, and notes the practice by which certification may be maintained. 

 

Required experience for different courses

  • SCWI, The Senior Certified Welding Inspector  is a person with at least 15 years experience, including 6 years experience while certified as a Certified Welding Inspector (CWI). 
  • CWI, Certified welding inspector, Candidates with high school education, either by diploma or state or military equivalence, must have at least 5 years experience. Individuals with eighth-grade schooling are required to have not less than 9 years of job experience to qualify for the examination. For individuals with less than eighth-grade schooling, not less than 12 years is required.
  • CAWI, A subordinate level of qualification is the Certified Associate Welding Inspector (CAWI), which requires fewer (2) years of experience for each educational level.

  • Beyond completion of the examination, the test candidate must undergo an eye examination to assure that the individual possesses adequate vision, whether natural or corrected.
  • After all test results are successfully completed, the individual is considered qualified to perform visual inspection of welds. 

 

The important aspect of every course is the exam, so we should know about the exam pattern before attempting it.

  • Part A-Fundamentals. The Fundamental examination is a closed book test consisting of 150 multiple-choice questions.
  • Part B-Practical. The Practical examination consists of 46 questions. It requires measurement of weld replicas with provided measuring tools, and evaluation in accordance with a supplied "Book of Specifications."
  • Part C-Open Book Code. This portion consists of questions on the code the individual has selected for this part of the examination. 

For each part, 2 hrs would be provided to complete the exam.

 

Code options for CWI exam

As discussed earlier Part C-Open Book Code. This portion consists of questions on the code the individual has selected for this part of the examination. The following codes are applicable to this portion of the examination: 

  •  AWS D1.1, Structural Welding Code-Steel, 
  •  AWS D1.5, Bridge Welding Code,
  •  AWS D15.1, Railroad Welding Specification for Cars and Locomotives
  •  API 1104, Welding of Pipelines and Related Facilities, 
  • ASME Section VIII and ASME Section IX, ASME B31.1, ASME B31.3

 

AWS Papers and Score to Qualify

Let us study CWI Exam – Comprise of three papers

Part A- Fundamentals - 2 hrs. - 150 questions closed book

Part B - Practical - 2 hrs.   - 46 questions, measurements, calculations

Part C - Code - 2 hrs.  - 60 questions, open book

To qualify for the AWS CWI Exam Success, The candidate must

▪          Must Pass All Three Parts With:

▪          72% Minimum for CWI  ( 71.7% )

▪           50% Minimum for CAWI

 

AWS realizes the need for standardized terms and definitions for use by those involved in the fabrication of welded products.
