AWS C3.7M/C3.7-2011 (R2022): Specification for Aluminum Brazing
| Size: 5.36 MB| Format:PDF| Quality:Scanner| Publisher: American Welding Society, Inc. (AWS) | Year: 4th Edition, 2011| pages: 34
AWS C3.7M/C3.7, 4th Edition, 2011 - Specification for Aluminum Brazing
This specification presents the minimum fabrication and quality requirements for brazing of aluminum and aluminum alloys. Its purpose is to standardize brazing process requirements and control brazed joint quality for all applications for which brazed joints of assured quality are required. This document establishes the minimum requirements for processes and products with a minimum of explanatory information so that sources of ambiguity are minimized. It assigns responsibility for the ultimate quality of the brazed product to a single organization and permits that organization to modify requirements if appropriate to the application. It requires proper documentation of any such modification.

AWS C3.3-2008 (R2016): Recommended Practices for the Design, Manufacture, and Examination of Critical Brazed Components
| Size: 6.05 MB| Format:PDF| Quality:Scanner| Publisher: American Welding Society, Inc. (AWS) | Year: 3rd Edition, 2008 (2016)| pages: 58
AWS C3.3, 3rd Edition, 2008 - Recommended Practices for the Design, Manufacture, and Examination of Critical Brazed Components
These recommended practices encompass those procedures that should be followed in the design, manufacture, and examination of brazed joints for critical components in order to assure their reliability in service.
The procedures recommended represent the best current practice and are necessary to the control of brazed joint quality. These practices are applicable to all products and brazing processes. Whenever any or some of these practices are omitted when producing critical components, the omission should be the result of a rational decision, not the result of a lack of knowledge of the best practice.
This document is divided into clauses addressing materials, design, manufacturing, and examination. These clauses are followed by Annex A, which presents a list of informative references; Annex B, which presents sample specifications that are intended as guides for the preparation of the user’s documents; Annex C, which presents a discussion of brazing risk management; Annex D, which presents a table relating to the quantification of the scope and magnitude of braze-induced discontinuities; Annex E, which presents systematic criteria for design of brazed components; and Annex F, which presents guidelines for the requesting of an official interpretation of an AWS standard.

AWS C3.2M/C3.2-2019: Standard Method for Evaluating the Strength of Brazed Joints
| Size: 6.29 MB| Format:PDF| Quality:Scanner| Publisher: American Welding Society, Inc. (AWS) | Year: 5th Edition, 2019| pages: 48
WS C3.2M/C3.2, 5th Edition, 2019 - Standard Method for Evaluating the Strength of Brazed Joints
The purpose of this standard is to describe the test methods used to obtain reliable data on the strength of metallic-to-metallic, metallic-to-nonmetallic, and nonmetallic-to-nonmetallic brazed joints. Test specimens preparation and testing is described to provide consistent and proper fabrication, brazing practices, and test results. Interpretation of the test results is the responsibility of the user.
Documentation of the materials, brazing parameters, and test conditions are required to allow comparison of results with the joint strengths obtained by others using this standard method. General use of this standard method may permit a compilation of brazed joint strengths and brazing design criteria at some future time.

| Size: 4.21 MB| Format:PDF| Quality:Scanner| Publisher: American Welding Society, Inc. (AWS) | Year: 2nd Edition, 2018| pages: 31
AWS C2.23M/C2.23, 2nd Edition, 2018 - Specification for the Application of Thermal Spray Coatings (Metallizing) of Aluminum, Zinc, and Their Alloys and Composites for the Corrosion Protection of Steel
Included are requirements for surface preparation, coating application, repair of coating defects, measurement of coating thickness, adhesion testing of the applied coating, and application of sealers and topcoats over the thermally sprayed metal coating. Not included in this standard are requirements for design and fabrication, thermal spray equipment qualification, coating selection, and operator and inspector certification. For successful thermal spray application, the steel structure and components should be designed and fabricated in accordance with NACE SP0178.1 Additional consideration should be given to weldments and components, or structures with thermal cut edges, whose hardness may preclude adequate profile depth.

This standard describes the essential elements of a procedure to verify performance of equipment and systems used for thermal spraying. These equipment and systems include the thermal spray gun, gas console, control apparatus, and feedstock supply system. Other external systems and apparatus such as a gas or fuel management system, sound abatement, dust collection, automation, fire suppression, and finishing systems are beyond the scope of this document.
This specification does not address all of the thermal spray process variations or equipment configurations. However, the principles presented may be a starting point for establishing a customized verification procedure.
It is not the intent of this standard to address process validation; to ensure a process is producing, or capable of producing, desired coatings. This specification does not address all of the essential process variables necessary for thermal spray process qualification. This specification does not address equipment design standards, provisions, requirements, codes, or regulations that may apply to the thermal spray equipment or its installation.
The standard can be applied at the time of installation and any other times or intervals the User deems appropriate to ensure the equipment is capable of operating to the manufacturer’s specifications or other specifications deemed applicable by the User.

AWS C2.20/C2.20M-2016: Specificatiopn for Thermal Spraying Zinc Anodes on Steel Reinforced Concrete
| Size: 6.66 MB| Format:PDF| Quality:Scanner| Publisher: American Welding Society, Inc. (AWS) | Year: 2nd Edition, 2016| pages: 48
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.
