Tests are performed by licensed welding assessors making use of a variety of instruments and techniques. These exams provide information regarding the dimension and quality of the weld.


These documents include Welding Procedure Specs (WPS), welder credentials, examination documents, project specifications, and suitable welding codes. A good CWI knows and understands the requirements and code. He or she makes certain that the WPS and welder credentials adjust to those needs. Before welding, CWIs evaluate both base steels and filler metals, noting that they abide by the WPS and project specifications.


During construction, CWIs check a selection of items to make sure that the WPS and task specs are being appropriately followed.
