One such method is extrusion of billets withsubsequent cold working, by drawing, swaging, or rocking,wi

35、th intermediate anneals until the final dimensions arereached.5.4 Unless otherwise agreed upon between the manufacturerand purchaser, welded tubing shall be made from flat-rolledproducts by an automatic or semiautomatic welding processwith no addition of filler metal in the welding operation. Otherm

36、ethods of welding, such as the addition of filler metal or handwelding, may be employed if approved by the purchaser andtested by methods agreed upon between the manufacturer andthe purchaser. If filler wire is used, it must meet the chemicalrequirements of the appropriate grade as shown in Table 4.

37、Welded tube is normally cold reduced to the desired dimen-sions by such methods as drawing, swaging, or rocking.

The strength values listed above arefor alloys that contain oxygen concentrations in the range

45、900 to 1400 ppm. For alloys with other oxygen concentrations, the tensile properties are to be agreed uponbetween the manufacturer and the purchaser.BTo be agreed upon between the manufacturer and the purchaser.CThe tensile test is to be carried out at one or more of the temperatures listed in Table
