Introduction14:08
Do you want to become a
Certified Welding Inspector?
If yes,
Are you a degree holder or Diploma holder in Engineering with 2 to 3 years of experience in a related field ?
If yes, you can become a Certified Welding Inspector of AWS.
Certified Weld Inspectors are highly valuable assets for International Companies and more beneficial to any organization hiring the Certified Inspectors
Welding is one of the most complex services within the industry and depends upon individual welder skills.
After specialized training in CWI the Certification of CWI brings an un-comparable depth of welding expertise
This gets unlocks the greater levels of consistency and quality to the welding skills.
CWIs are in High demand in the Industry
Because CWIs can understand the intricacies of compliance and welding codes.
Before the welding process, they know which process will be the most favorable for a given task.
They also understand the required presets of machinery, equipment, alignment, and joint positions, etc.,
During the welding, they can identify the proper usage of equipment and assist the welders with welding specifications.
There are plenty of job opportunities waiting for you
Dubai,
Oman,
Saudi Arabia,
Qatar,
Kuwait,
Canada,
USA,
Kazakhstan, and in many other Countries all over the World.
A CWI is a must for every Welding and Fabrication Industry to run its activities with quality and Safety.
A CWI is a must for every QA/QC department if the Company wants to produce quality products as per the International Standards safely.
