AWS C2.16-C2.16M pdf free download.Guide for Thermal-Spray Operator Qualification.
arc spraying (ASP). A thermal-spray process using an arc between two consumable electrodes of surfacing materials as a heat source and a compressed gas to atomize and propel the surfacing material to the substrate.
automatic thermal spraying. Thermal spraying with equipmcnt that requires only occasional or no ohscrvation of the thermal spraying, and no manual adjustment of the equipment controls (see Table 2).
flame spraying (FLSP). The thermal spray process in which an oxyfuel gas flame is the source of heat for melting the surfacing material. Compressed gas may or may not he used for atomizing and propelling the surfacing material to the substrate.
high velocity oxygen fuel (HOF). A thermal spraying process using a high pressure, oxyfuci mixture to heat and propel a powdered surfacing material to a substrate.
manual thermal spraying. Where the spraying gun is manipulated by hand (see Table 2).
mechanized thermal spraying. Thermal spraying with equipment that requires manual adjustment of the equipment controls in response to visual observation of the thermal spraying. Where some aspects of the proccss arc mechanized, with the gun not manipulated by hand (see Table 2).
plasma spraying (PSP). The thermal-spray process in which a non-transferred arc is used to create an arc plasma for melting and propelling the surfacing material to the substrate.

4. Qualification Requirements
4.1 Qualification i’est. The thermal-spray operator applicant should flied the knowledge and skill requirements of the TSOQT for which he or she is to be qualified. The Job Knowledge requirements arc detailed in TSOQT No. JK-l.
The skill requirements are detailed in the specific TSOQT for the qualification classification listed in Table I, for which he or she is being tested.
The applicant should:
(1) Prepare the thermal-spray process and spray paranielers data sheet (Table I of the respective TSOQTs) from the thermal-spray-equipment manufacturers and fecdstock information. The Test Supervisor will review. correct as appropriate, and approve the applicant’s process and parameters data sheet prior to conducting the thermal-spraying test. Section 5 of the TSOQT.
(2) Prepare and thermal-spray the test specimens in accordance Sections 4 and 5 respectively, of the TSOQT.
(3) Meet the examination requirements, Section 6 of the TSOQT.
4.2 Test Supervisor. Qualification testing should be performed under the direction of a person designated as the Test Supervisor by thc managcmdnt of the Thermal- Spray Employer.AWS C2.16-C2.16M pdf download.
