This standard presents a system for indicating
welding, brazing, and nondestructive examination requirements.

The system includes provisions for the graphical
representation of welds, brazes, and nondestructive examination
methods with conventions for specifying, at a
minimum, the location and extent of their application.
Optional elements and supplementary symbols provide a
means for specifying additional requirements.

The figures included with the text are intended to show
how the correct format and applications of symbols may
be used to convey welding, brazing, and nondestructive
examination information. They are not intended to represent
recommended welding, brazing, nondestructive
examination, or design practice.

The clause addressing brazing uses the same symbols
that are used for welding. The clause on nondestructive
examination symbols establishes the symbols to be used
on drawings to specify nondestructive examination for
determining the suitability of components. The nondestructive
examination symbols included in this standard
represent nondestructive examination methods as discussed
in the latest edition of AWS B1.10M/B1.10,
Guide for the Nondestructive Examination of Welds. Definitions
and the details for the use of the various nondestructive
examination methods are found in AWS
B1.10M/B1.10.

The limitations included in specifications and codes are
also beyond the scope of this standard.

welding, flux cored stainless steel rods for root pass welding with the gas tungsten arc process, and metal cored stainless
steel electrodes for gas metal arc welding, gas tungsten arc welding, plasma arc welding, submerged arc welding, and
any other process to which they may be applied.

The chromium content of undiluted weld metal from these electrodes and rods is not less than 10.5% nominal and the
iron content exceeds that of any other element. For purposes of classification, the iron content shall be derived as the balance
element when all other elements are considered to be set at their specified minimum values.

Safety and health issues are beyond the scope of this standard and, therefore, are not fully addressed herein. Some safety
and health information can be found in Annex Clauses A5 and A10. Safety and health information is available from
other sources, including, but not limited to, ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes, and applicable
state and federal regulations.

This specification uses both U.S. Customary Units and the International System of Units (SI). The measurements are not
exact equivalents; therefore, each system must be used independently of the other without combining in any way when
referring to material properties. The specification with the designation A5.22 uses U.S. Customary Units. The specification
A5.22M uses SI Units. The latter are shown within brackets ([ ]) or in appropriate columns in tables. Standard
dimensions based on either system may be used for sizing of filler metals or packaging or both under A5.22 or A5.22M
specifications.

The standard Guide for the Fusion Welding of Zirconium and Zirconium Alloys provides instructional guidance for thewelding of zirconium and zirconium alloys. This guide explains processes, equipment, materials, workshop practices,joint preparation, welding techniques, tests, and the repair of defects.

Scope

1.1 This specification establishes the attributes required for determining the qualification of welding educators.

1.2 In the qualification process, a welding educator shall be capable of performing welding skills and demonstrate their
knowledge of welding processes and fabrication principles. The welding educator shall furnish documentation showing
that they meet the requirements of their training facility with regard to education and instructional methods. The documentation
may be in the form of educational transcripts, certificates, or written recommendation from a senior educational
institution administrator attesting that the welding educator meets the educational requirements of that facility.

1.3 It shall be the responsibility of the employer to determine that a person is capable of performing the duties involved
in their welding educator assignment.

1.4 This specification is intended to supplement the requirements of an employer, or of local, state, or national regulations;
it shall not be construed as a preemption of the employer?s responsibility for the work or the performance of the
work. Hence, it is the responsibility of the employer to determine the welding educator?s qualifications, other than those
stated in 1.2 above, and confirm the capability of the welding educator to perform the duties required by the organization
for the job function assigned to the welding educator. Furthermore, this standard is not intended to supersede, replace, or
contradict the local, state, or national regulations governing the licensing of teachers or instructors and the exemptions, if
any, permitted by such regulations with regard to teaching or instructing welding without a license.

1.5 This specification does not require units of measure. Therefore, no equivalents or conversions are contained herein.

1.6 Safety and Health issues are beyond the scope of this specification and therefore are not fully addressed herein. Safety
and health information is available from other sources, including, but not limited to, ANSI Z49.1, Safety in Welding, Cutting,
and Allied Processes, and applicable federal and state regulations (also see note in 5.1).

1.7 Terminology. As used in this specification, the word shall denotes a requirement; the word should denotes a guideline
or recommendation; and the word may denotes a choice
