The AWS Certification Program for Robotic Arc Welding - Operators and Technicians (CRAW) allows many welding personnel employed in various welding sectors to measure themselves against standards for their occupation. It also signifies that the CRAW Operator or Technician has demonstrated the capability of working with various codes, standards, and specifications. Since proof of active practice or re-examination is required every three years, certification also signifies that the CRAW Operator or Technician is current with the welding industry.
CRAW Approved Testing Centers
AWS CRAW Approved Testing Centers (ATCs) prepare individuals for certification and administer both the practical and written exams at their respective facilities.
Do you have the necessary arc welding equipment to test individuals to the requirements of the Certified Robotic Arc Welding (CRAW) program? If so, consider applying for AWS Approved Testing Center (ATC) designation. As a designated CRAW ATC, your facility enjoys valuable industry recognition, including your AWS website listing and periodic Welding Journal magazine advertising. Visit the ATC Facility Accreditation information page: CRAW APPROVED TESTING CENTER.
Requirements for CRAW Exam Qualification
The AWS D16.4:2005 Specification for the Qualification of Robotic Arc Welding Personnel and the QC19, Specification for AWS Certification of Robotic Arc Welding Personnel sets the experience and education requirements for taking the CRAW examination and provides training recommendations:
High school graduate or have achieved a state or military approved high school equivalency (e.g., GED).
Operator and Technician
MANUAL OR SEMIAUTOMATIC ARC WELDING PROCESSES AS A WELDER
At least 6 months.
Operator and Technician
EXPERIENCE AS A WELDER (INCLUDING ROBOTIC AND AUTOMATIC OPERATOR)
Includes the before mentioned 6 months of manual or semiautomatic arc welding.
Operator = 12 months
Technician = 18 months
EXPERIENCE IN AN OCCUPATIONAL FUNCTION THAT HAS A DIRECT RELATIONSHIP TO WELDING OR ROBOTICS
Includes welder experience listed above and other functions such as inspector or quality control.
Operator = 3 or more years
Technician = 5 or more years
POST-SECONDARY SUBSTITUTION FOR EXPERIENCE
Post-secondary education in welding, technical, robotic, technology, electrical, or engineering discipline, may be substituted for an equal number of years, but not more than 2 years.
- Post-secondary education may not be substituted for or credited toward the before mentioned experience requirements of (6) months of manual or semiautomatic arc welding processes as a welder.
Operator and Technician
- Post-secondary education may not be substituted for the months of experience as a welder.
Operator = 12 months (including robotic and automatic operator)
Technician = 18 months (including robotic and automatic operator)
Hold current CWI (Certified Welding Inspector) certification. Current CWI certification is a requirement for the CRAW-T certification. Failure to achieve and/or maintain CWI certification will result in the CRAW-O certification ONLY.
Operator: Completion of original equipment manufacturer or equivalent Robotic Programming Course.
Technician: Receive instruction in the operation of quality measuring tools including applicable computer software for measuring the weld cross section. Also, be familiar with personal computers.

Training is offered by several AWS Approved Testing Centers (ATCs). Be sure to contact an ATC representative to submit your application and schedule your CRAW training and exam.
|Examination||Minimum number of questions|
|Part A: CRAW FUNDAMENTALS||136|
|Part B: CRAW PRACTICAL||30|
Each of the two examinations shall not have an individual score less than 75%. The examination is two hours long. Part A exam consists of 136 multiple choice questions. The exam will be given in a closed book format. The Part B practical exam is performance based and consists of 30 tasks that cover the practical demonstration of knowledge and ability involving a robotic system and are completed in sequential order. The CRAW written examination subjects are listed in AWS QC19, Specification for AWS Certification of Robotic Arc Welding Personnel. In preparation for the practical examination, candidates may use the CRAW Performance Test- Candidate Information Booklet. Both parts of the exam will be conducted at the same AWS Approved Testing Center.
Registration/Application for Training and Exams
Welding personnel who wish to be trained and tested for CRAW certification can do so by contacting an ATC representative at any of the AWS CRAW Approved Testing Centers (ATCs).
If an individual fails any portion of the CRAW exam, contact the AWS Approved Testing Center (ATC) representative to schedule a date to retest.
If you're a veteran with G.I. Bill Benefits, and you're looking for a good job, or you want to change jobs, or if you want to move ahead in your present job, licensing or certification may hold the key for you!

A CRAW Renewal Application must be submitted with the appropriate fees to the AWS. The CRAW Operator or Technician shall renew his/her certification every three years by reexamination.
Alternatively, the CRAW Operator or Technician can meet the following requirements for renewal without examination:
- Attest to two years activity, of their three-year certification period, in the practice of welding or related activities.
- One of the two years of activity may be fulfilled by satisfactory documentation of the completion or teaching of a minimum of forty (40) contact hours of training courses whose content must be in the occupational skill of welding, or subjects related to welding, its application, control, materials, and processes as indicated in QC19, Specification for AWS Certification of Robotic Arc Welding Personnel.
After nine years from the date of initial certification, and each nine years thereafter, recertification shall be granted by meeting one of the following requirements:
- Completing the current performance test of the CRAW Operator or Technician examination (current test at the time of application for re¬certification)
- Documenting two (2) years of continued activity in inspection, welding, design, production, construction, or repair, during the last three years of certification, and by presenting evidence of participation in one or more of the activities listed in QC19, Specification for AWS Certification of Robotic Arc Welding Personnel totaling 80 contact hours and documented as 8 CEUs, or 80 PDHs in combination.
