This part comprises principles in terms of the qualification of welding and brazing tactics as required through different Code Sections for part manufacture. It additionally covers principles on the subject of the qualification and requalification of welders, brazers, and welding and brazing operators so they may well practice welding or brazing as required by means of different Code Sections within the manufacture of parts. Welding and brazing information disguise crucial and nonessential variables particular to the welding or brazing method used

Sample text

B) Position 2FR. Pipe with its axis horizontal and the axis of the deposited weld in the vertical plane. The pipe is rotated during welding. 6, illustration (c). 1 Stud Welding. 1). In all cases, the stud shall be perpendicular to the surface of the plate or pipe. 8. 3 Overhead Position 4F. Pipe with its axis vertical so that the weld is deposited on the underside of the horizontal surface and against the vertical surface. The axis of the weld will be horizontal and the pipe is not to be rotated during welding.

4(c). The test coupon for plate-to-plate shall be cut transversely to provide a center section approximately 4 in. (100 mm) long and two end sections, each approximately 1 in. (25 mm) long. For pipeto-plate or pipe-to-pipe, the test coupon shall be cut to provide two quarter sections test specimens opposite to each other. One of the test specimens shall be fracture tested in accordance with QW-182 and the other macroexamined to the requirements of QW-184. 2(h). 2 Acceptance. The acceptance criteria shall be in accordance with that Section specifying impact requirements.

1(b) may be used for tension tests on all thicknesses of pipe having an outside diameter greater than 3 in. (75 mm). (a) For thicknesses up to and including 1 in. (25 mm), a full thickness specimen shall be used for each required tension test. (b) For pipe thicknesses greater than 1 in. 2(d) are complied with. (c) When multiple specimens are used, in lieu of full thickness specimens, each set shall represent a single tension test of the full pipe thickness. Collectively, all of the specimens required to represent the full thickness of the weld at one location shall comprise a set.
