scope:

This specification provides requirements for the design and manufacture of welded joints of hydraulic cylinders. When specified in the purchasing documents, compliance with all the requirements shall be required. This specification does not apply to the manufacture of welded tubing used for hydraulic cylinders which is covered under ASTM and other recognized specifications. This specification does not specify load determination, design assumptions, safety factors, or calculation methods for non-weld related areas of the hydraulic cylinder. 1.1.2 The Manufacturer's adherence to this specification shall include responsibility for the following: (1) welding, as defined in 1.1.1, in accordance with this specification; (2) producing welds as designated on drawings by appropriate symbols and notes, with sufficient detail to show joint preparation compatible with applied processes; (3) providing written welding procedure specifications (WPSs); (4) recording and maintaining results of all welding procedure and welder performance qualification tests; (5) controlling use of designated base metals and welding consumables; (6) inspecting the welds to the requirements of this specification; (7) having a welding quality program in place. The requirements of AWS B5.17, Specification for the Qualification of Welding Fabricators may be used as a guide in establishing this welding quality program. Accreditation of quality systems of welding fabricators may be obtained through the AWS Certified Welding Fabricator (CWF) or equivalent programs. 1.2 Units of Measure. This specification makes use of both U.S. Customary Units and the International System of Units (SI). The measurements may not be exact equivalents; therefore each system must be used independently of the other without combining them in any way. The specification with the designation D14.9 uses U.S. Customary Units. The specification D14.9M uses SI Units. The latter are shown in appropriate columns in tables and figures or within brackets [ ] when used in the text. Detailed dimensions on figures are in inches. A separate tabular form that relates the U.S. Customary Units with SI units may be used in tables and figures. 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. 1.4 Symbols. Welding symbols shown on drawings shall be compatible with those shown in AWS A2.4, Standard Symbols for Welding, Brazing, and Nondestructive Examination. In addition, welding symbols not conforming to the requirements of AWS A2.4, but conforming to the requirements of this specification may be allowed on drawings. Special conditions or deviations shall be fully explained by added notes, details, or definitions on the drawings.
