AWS C2.20/C2.20M, 2nd Edition, 2016 - Specificatiopn for Thermal Spraying Zinc Anodes on Steel Reinforced Concrete
This standard covers the application of zinc thermal spray coatings to steel reinforced concrete using arc and flame spray equipment. The application of the zinc on steel reinforced concrete requires an electrical connection to the steel reinforcement. Although other metals can also be applied with these methods and equipment, at this time the standard only covers zinc and zinc alloys. This standard is formatted as an industrial process instruction: job description, safety, Pass/Fail Job Reference Standard, feedstock materials, equipment, a step-by-step process instruction for surface preparation, thermal spraying, quality control (QC), and a Job Control Record.
This standard is based on the literature, equipment, process developments, and industrial practices known at the time of publication. This standard does not cover the design standards or recommended practices for cathodic protection (CP) systems. The design of a CP system for reinforced concrete structures, including the connection of the zinc coating to the steel reinforcement, should be undertaken by an experienced and qualified Corrosion Engineer. Table 1 summarizes inspection, test methods, and acceptance criteria that shall be employed.

AWS C2.19/C2.19M, 1st Edition, 2013 - Specification for the Application of Thermal Spray Coatings to Machine Elements for OEM and Repair
This specification covers thermal spray processes for original equipment manufacturers (OEMs) and the repair of machinery components. The scope includes (1) recommended applications, (2) management and engineering requirements, (3) equipment and facility requirements, (4) feedstock materials, and (5) application processes for thermal spray coatings.
The thermal spray processes covered by this standard are combustion and high velocity oxygen fuel powder, electric arc, and plasma processes that use either powder or wire as feedstock.
Development of this standard was initiated at the request of the U.S. Navy to replace MIL-STD-1687A (SH), Thermal Spray Processes for Naval Ship Machinery Applications. It contains Annex B that the Navy may still use as their guide for surface ship applications. Annex B also lists Navy applications that are permitted and those that are prohibited, including the certification, approval requirements and protocols for handling U.S. Navy components.
Others may use this standard and annexes as a guide to establishing contract document requirements between equipment owners (purchaser) and thermal spray coating contractors where they may choose to invoke all or only a portion of this specification's requirements as fits the needs of their work.

This guide contains recommendations for establishing, conducting, and maintaining a thermal spray operator qualification program. Such programs generally include training, knowledge and skill testing, and documentation requirements. The skill tests described in this guide relate to flame spraying, arc spraying, atmospheric plasma spraying, and high velocity oxygen fuel (HVOF) spraying.
While this guide does not preclude the possibility to establish a qualification program for operators of automatic thermal spray equipment, the examples in this guide assume the objective is to qualify operators who develop process parameters, apply the thermal spray process, and evaluate the effectiveness of the coating process.
This document is not to be used as a stand-alone document for operator qualification or certification. An operator would not be “qualified in accordance with AWS C2.16/C2.16M” as this document does not address relevant acceptance standards. However, a qualification program can state that it follows the guidelines of AWS C2.16/C2.16M.
Although this guide is not written with mandatory requirements, mandatory language, such as the use of “shall,” will be found in those portions of the document where failure to follow the instructions or procedures could produce inferior, misleading, or unsafe results.

AWS APG-DISC- POCKET GUIDE FOR VISUAL EXAMINATION OF WELDS – DISCONTINUITY CAUSES AND REMEDIES
| Size: 4.3 MB| Format:PDF| Quality:Scanner| Publisher: American Welding Society, Inc. (AWS) | Year: 2018| pages: 45
Visual examination (abbreviation: VT) is the primary method for identifying welding discontinuities. It is fundamental to any effective quality control program. It is also fundamental to assuring weld repair operations are effective and comply with the approved contract documents. For convenience and brevity, all rework and repair activities in this pocket guide are called repairs. As a minimum, various steps in any repair are always examined and evaluated. Welders and inspectors, alike, will examine the repair efforts and compare them with project requirements. Even "close enough" is an evaluation. It has been proven time and time again that integrating quality control actions into fabrication and installation operations reduces labor efforts and repair costs. Early detection of welding discontinuities and other quality failures saves money and time.
