| Size: 18.2 MB| Format: PDF| Quality: Scanner| Year: 1st Edition, 2013| pages: 64

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.

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.
