AWS Updates C2.16 Guide for Thermal Spray Industry

thermal spray

The American Welding Society has updated their C2.16/C2.16M:2017, Guide for Thermal Spray Operator Qualification Programs. 

The purpose of the technical publication is to provide a guide for companies, agencies, and institutions, to create a program for qualifying thermal spray operators. Such qualification programs are frequently specific to the employer or testing site.

Information related to training, knowledge and skill testing, and coating system inspection methods is provided. Example thermal spray operator qualification tests (TSOQT) parameters and forms are provided, to address common engineering and corrosion control applications using arc, flame, atmospheric plasma, and high velocity oxygen fuel (HVOF) spray processes.

Previous editions of the document are as follows:

  • ANSI/AWS C2.16-78, Guide for Thermal Spray Operator and Equipment Qualification
  • ANSI/AWS C2.16-92, Guide for Thermal Spray Operator Qualification
  • AWS C2.16/C2.16M:2002, Guide for Thermal Spray Operator Qualification

This edition has been extensively revised and reformatted to clarify the intent and readability. Because of this, the vertical line in the margin or underlined text in clauses, tables, or figures common to AWS standard revisions has not been applied to indicate editorial or all technical changes from the previous edition.

Comments and suggestions for the improvement of this standard are welcome. They should be sent to the Secretary, AWS C2 Committee on Thermal Spraying, American Welding Society, 8669 NW 36 St, # 130, Miami, FL 33166.
