AWS J1.3:2020 pdf download.Specification for Materials Used in Resistance Welding Electrodes and Tooling
1.1 Scope.
AWS J1.3 addresses common copper alloy and composite materials employed in the manufacture of resistance welding electrodes, resistance welding dies, and related components such as adapters. holders, and structural components of the welding circuit.
This standard addresses bar, rod (straight lengths and coils), plate, and casting forms of select materials. The standard does not address material in sheet form.
The standard does not include all copper and copper base materials that may be applied in the construction of resistance welding machines or tooling. Examples of materials not currently covered are: electrolytic tough pitch (ETP) copper, brass, and bronze.
Unique, specialized, and new materials exist in domestic and international marketplaces and their absence here should not be interpreted as a commentary on their suitability for a particular application.
1.2 Units of Measurement. This guide makes use of both the U.S. Customary Units and 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 must 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:
(I) ANSI Z49. I, Safi’tv in Welding. Cuiting. and A I/led Pnwe.v.ces
(2) AWS Safety and Health Fact Sheets
(3) Other safety and health information on the AWS website Material or Equipment Manufacturers:
(1) Safety Data Sheets (SDS), or Product Safety Data Sheets (PSDS), 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. I should be considered when developing the safety program.AWS J1.3 pdf download.
