One such method is extrusion of bill

Othermethods 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
39、 chemicalrequirements of the appropriate grade as shown in Table 4.Welded tube is normally cold reduced to the desired dimen-sions by such methods as drawing, swaging, or rocking.
