AWS C3.11M/C3.11:2011

This specification describes relevant equipment, fabrication procedures, and quality (inspection) requirements for the torch soldering of materials. This document includes criteria for classifying torch-soldered joints based on loading and the consequences of failure and quality assurance criteria defining the limits of acceptability in each class.
Scope : 1.1 Scope. This specification presents the minimum process and quality requirements for the torch soldering of ceramics, precious metals, and refractory metals, as well as the alloys of copper (Cu), iron (Fe), nickel (Ni), aluminum (Al), magnesium (Mg), tin (Sn), lead (Pb), and zinc (Zn). The purpose of this specification is to standardize torch soldering process requirements that will ensure that soldered joints attain the quality level designated by the application. This document establishes the minimum requirements for processes using a minimum amount of explanatory information so as to limit any ambiguity. This document assigns responsibility for soldered joint quality to the Organization Having Quality Responsibility and permits that organization to modify requirements as necessary. However, this specification requires that proper documentation be developed and archived by that organization, which explains the basis and specific details of any such modifications. 1.2 Units of Measurement. This standard makes use of both the International System of Units (SI) and U.S. Customary Units. The latter are shown in brackets ([ ]) or in appropriate columns in tables and figures. The measurements may not be exact equivalents; therefore each system must be used independently. 1.3 Safety. Safety and health issues and concerns are beyond the scope of this standard; some safety and health information is provided, but such issues are not fully addressed herein. Safety and Health information is available from the following sources: American Welding Society: (1) ANSI Z49.1, Safety in Welding, Cutting, and Allied Processes (2) AWS Safety and Health Fact Sheets (3) Other safety and health information on the AWS website Material or Equipment Manufacturers: (1) Material Safety Data Sheets supplied by the materials manufacturers (2) Operating Manuals supplied by equipment manufacturers Applicable Regulatory Agencies Work performed in accordance with this standard may involve the use of materials that have been deemed hazardous, and may involve operations or equipment that may cause injury or death. This standard does not purport to address all safety and health risks that may be encountered. The user of this standard should establish an appropriate safety program to address such risks as well as to meet applicable regulatory requirements. ANSI Z49.1 should be considered when developing the safety program.
