AWS C7.2:2010

This document presents recommended practices for laser beam welding, cutting, drilling, and transformation hardening. It is intended to cover common applications of the process. Processes definitions, safe practices, general process requirements and inspection criteria are provided.
Scope : These recommended practices present a description of laser beam equipment and procedures that can be used for welding, cutting, drilling, and transformation hardening of various materials. These recommended practices stress the process basics, parameters, and applications. Practical information has been included in the form of figures, tables, and graphs which should prove useful in determining capabilities and limitations in the processing of various materials. Readers who desire additional information about lasers and laser materials processing should consult the Reference Documents shown in Annex A, as well as the various references given throughout this document. Any specific manufacturer product depicted in any sketch, figure, table, or product description in the document, shall not be construed as an endorsement of that particular manufacturer or product by AWS. This standard makes sole use of the International System of Units (SI). Safety and health issues may not be fully addressed by this standard. Users of this standard should consult ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes, applicable federal, state, and local regulations, and other relevant documents concerning safety and health issues not addressed herein. ANSI Z136.1, Safe Use of Lasers, is another important source for safe operation of laser equipment. Please consult Clause 4 for more information.
