Details
This specification on electron beam welding discusses applicable specifications, safety, requirements, fabrication, quality examination, equipment calibration and maintenance, approval of work, and delivery of work.
Scope : 1.1 Scope. This specification addresses processing and quality control requirements for electron beam welding. Processing includes both high- and low-voltage welding equipment and high and medium vacuum variations. 1.1.1 Materials. This specification covers all major engineering metals and alloys. 1.1.2 Qualification Categories. There are three categories to which welds may be qualified: Class A, B, or C. 1.1.2.1 Class A: Critical Applications. Critical weldments include those where a failure of any portion would cause loss of system, loss of major component, loss of control, unintentional release of critical stores (such as fuel or cargo), or endangerment of personnel. 1.1.2.2 Class B: Semicritical Applications. Semicritical weldments include those where a failure would reduce the overall efficiency of the system but loss of the system or endangerment of personnel would not be experienced. 1.1.2.3 Class C: Noncritical Applications. Noncritical weldments include those where a failure would not affect the efficiency of the system or endanger personnel. 1.2 Units of Measure. This standard does not require units of measure. Therefore, no equivalents or conversions arecontained except when they are cited in examples. 1.3 Safety. Safety issues and concerns are addressed in this standard, although health issues and concerns are beyond the scope of this standard. 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) 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.
