• stainless steel tig welding wire Winding Requirements

  The filler metal shallbe wound so that kinks. waves.sharp bends.or wedging are not encountered leaving the filler metal free to unwind without restriction.The outside end of the filler metal(the end with which welding is to begin)shall be identified so that it can be readily located and shall be fastened to avoid unwinding.

  The cast and helix of all filler metal in coils and spools shall be such that the filler metal will feed in an uninterrupted manner in automatic and semiautomatic equipment.

  The cast and helix of drawn,solid filler metal on 4 in.[100mm]spools shall be such that a specimen long enough to produce a single loop,when cut from the spool and laid unrestrained on a flat surface, will do the following:

  1. Form a circle not less than 2.5 in.[65 mm]nor more than 15 in [380mm] in diameter

  2. Rise above the flat surface no more than 1/2 in.[13 mm] at any location.

• stainless steel welding wire chart Filler Metal Identification

   

  The product information and the precautionaryinformation required in Clause 17Marking ofPackages, shall also appear on each coil and each spool.

  Each bare straight filler rod shall be durably marked with identification traceable to the unique product type of the manufacturer or supplier. Suitable methods of identification could include stamping,coining,embossing, imprinting flag-tagging,or color coding.(If color coding is usedthe choice of color shall be as agreed between supplier and purchaser and the color shall be identified on the packaging.)When the AWS classification designation is used the“ER” may be omitted;for example“308L”for classification ER308L.Additional identification shall be as agreed upon between the purchaser and supplier

•  welding steel with stainless wire Packaging

  Filler metal shall be suitably packaged to ensure against damage during shipment and storage under normal conditions.

  The following product information (as a minimum of low temperature aluminum welding wire)

  shall be legibly marked so as to be visible from the outside of each unit package:

  (1) AWS specification and classification designation (year of issue may be excluded best wire for welding aluminum)

  (2) Supplier’s name and trade designation

  (3) Size and net weight

  (4) Lot, control, or heat number

1.  Oil, dirt and rust on the welding stainless with mild steel wire surface should be removed before welding. Surface impurities such as oil, rust and water should be thoroughly removed in the welding place, so as to prevent blowhole, crack and so on during welding. The surface of the groove and its surroundings should be polished with metallic gloss.
2. In order to obtain good mechanical properties of welding seam, suggest protect gas Ar+2%O2 and shield gas flow rate 20-25 L/min for gasless stainless steel welding wire. For TIG welding,suggest protect gas pure Ar and shield gas flow rate 8-15 L/min ,Arc length 1～3 mm; wind speed limit ≤ 1.0m/s，argon protection at the back of welding area .
3.  In the stainless steel welding wire flux core process, the welding line energy directly affects the mechanical properties and crack resistance of weld metal, and should be paid more attention to.
4. The above welding methods, conditions and specifications are for reference only. Users should evaluate the welding process according to their own welding characteristics before using the welding stainless steel with mild steel wire for the formal product welding.
