B863 – 10 lengths are normally 10 to 12 ft long (random). Exact lengths may be specified by the purchaser when necessary. 4.4 Filler Metal or Weld Wire—Wire for welding filler metal application has special requirements for more restrictive chemistry that allows for oxygen increase inherent in most welding processes used for titanium, and has tighter limits on iron, carbon, nitrogen, and hydrogen. AWS ER Ti-XX grades are specifically designed for welding the corresponding ASTM XX wrought or cast material grades. In addition, special requirements for spooling, such as layer winding, cast, and helix,...
