Description
I am an international welding inspector, comprehensive level (IWI-C).
My field of activity as a welding inspector is:
-Techniques of non-destructive testing, mechanical testing and visual inspection of welding
-Inspection procedures and acceptance criteria
-Material specifications and metallurgy
-Specifications of consumables
-Engineering drawings, joint adjustment and workshop tolerances
-Development and implementation of welding technology procedures and specifications
-Development and implementation of inspection procedures and acceptance criteria
-Quality control programs
-Welding equipment functionality and application/limitations
-International and national standards of qualification of welders
-Identification of defects in welded joints
-Inspection requirements based on national standards and regulations
Depending of requirements in ITP document, the main tasks of the welding inspector are:
-Interpretation of documentation and specifications
-Qualification of welding technology, welders and operators
-Checking the application of approed welding technologies
-Inspection before welding
-Chemical analysis
-Mechanical properties
-Base material defects
-Double layer and cracks
-Surface defects (errors)
-Flatness
-Edge preparation (including root and leveling)
-Dimensions
-Root opening (gap)
-Merger
-Inspection during welding
-Preheating and interlayer temperature
-Root passage
-Welding the root before welding the other passes
-Cleaning between passes
-Appearance of joints (sometimes comparison with workshop standard)
-Deviations from approved technology welding (current strength, etc
-Inspection after welding
-Post Weld Heat Treatment control
-Visual testing
-Appearance of the joint surface
-Compliance of joints with documentation
-Magnetic particles testing (MT)
-Liquid penetrant testing (PT)
-Radiography testing (RT)
-Ultrasonic testing (UT)
-Leakage test
-Destructive testing
-Metallographic testing
-Making welding inspection report
