You would use 316 as the filler, it is the more pertinent metal of the two.
inconel
It is a weld made by melting the edges of the materials to be joined, but adding no filler metal to the weld.
A heterogeneous weld corresponds to a weld that is realized with a different filler alloy than the base metal. At the opposite, a homogeneous weld is realized with same filler alloy than the base metal. Finally, an autogenous weld is done without filler alloy. The joining is realized by melting only the base metal. A.B.
The crown of the weld is the material of the filler metal that projects above the surface of the parts being joined by the weld.
You can use the 308 or 316.
Filler rods are used to add metal to a molten weld pool during the welding process and electrodes actually have electricity running through them to deposit metal into the weld with the exception of TIG welding where the tungsten electrode is used solely for heat.... Hope this was helpful
A form of arc welding in which the electrical energy used to weld the metal is conducted through a wire that is fed from a spool to act as a filler metal.
while doing the welding ,the weld metal should be deposit in the weld pool of parent material and electrode.In some type of welding like TIG ,the electode is not consumable ,it is used to create arc betwenn the electode and the parent material.In such cases,the filler metal or wire is used to join the parent material
Most material being welded to 2205 including itself, should be welded with 2209 filler wire.
The tungsteng electrode, because this one not is a filler metal in this process. The individual may be asking what metal can you not weld using the TIG process. In that case cast iron, zinc (including zinc coated metals), lead and any metal with a low melting temperature would be the answer.
filler rod Almost all metals produced can be welded. Electrodes/rods of similar or compatible metals are manufactured to weld these metals.
