Specification for resistance welding for aerospace applications
|Publication Date:||1 January 2013|
|ICS Code (Aircraft and space vehicles in general):||49.020|
|ICS Code (Welding processes):||25.160.10|
This specification covers requirements for resistance spot and seam welding of the following metals and their alloys 1.1.1 Material Groups Group 1-Aluminum and magnesium Group 2-Steel, nickel, and cobalt Group 3-Titanium 1.1.2 Classification. Classification is based on the following: Class A-A welded joint, whose failure during any operating condition would cause loss of the equipment or system or one of its major components. Class B-A welded joint whose failure would reduce the overall strength of the equipment or system or limit the intended functioning or use of equipment. Class C-A welded joint for which no stress analysis is required and whose failure would not affect the performance of the equipment or system. 1.2 Units of Measure. This standard makes use of both U.S. Customary Units and the International System of Units (SI). The latter are shown within brackets ([ ]) or in appropriate columns in tables and figures. The measurements may not be exact equivalents; therefore, each system shall be used independently.1.3 Safety. Safety and health issues and concerns are beyond the scope of this standard and therefore 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 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.

This specification provides the general resistance welding requirements for aerospace hardware. It includes, but is not limited to, resistance spot and resistance seam welding of aluminum, magnesium, iron, nickel, cobalt, and titaniumbased alloys. There are requirements for machine and procedure qualification, production witness samples, and inspection and acceptance criteria for aerospace hardware.View Less
