What does it mean by the crown of the weld?
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.
What is a fusion weld?
A fusion weld has no filler material. The pieces to be joined are touching and heat is applied at the joint. The edges melt and "fuse/weld" together. TIG or Oxy-fuel Welding is used. This type of welding is considered to be pure as nothing is added to the weld.
What is the material used for tac welding?
Tac welding is not a specific material. Tac welding is a form of welding, that welder's use in order to hold two pieces' of metal together to get a proper fit. The tac weld can be easily broken if the two pieces' of metal aren't in the right place. So if you tac weld anything, the filler is going to be whatever material you are welding.
What is the weld reinforcement shall fair smoothly from the weld to the base metal?
It means, that the Weld Bead/ Weld Metal must be very well blended with the Parent Material/ Base Metal. There shall be a smooth transition between the Base Metal and the Weld ( Face or Root ) Reinforcement without any sharp or sudden changes ( e.g. Sharp Edges- commonly seen on the weld toes-, Peaks, Metal Inclusions- filler wire/metal/material inclusion-, dents, sudden variations or deviations in the weld dimensions...). ..You're gonna be able to see more of this requirements in the aerospace industry.

How do you calculate welding filler metal in mig welding?
A number of factors go into this: base material thickness, joining material thickness, wire thickness, shielding gas composition, angle of weld, etc. The best way to determine this is to measure your material, then open your MIG welder, find the wire size of the spool, and read the chart inside of the MIG Welder door.

What filler metal is used to weld 308 stainless steel to 316 stainless steel material?
You can use the 308 or 316.

What is the purpose of a filler rod in welding?
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
What is a Autogenous weld joint?
It is a weld made by melting the edges of the materials to be joined, but adding no filler metal to the weld.
What filler metal is used to weld 304 stainless to 316 stainless?
Most material being welded to 2205 including itself, should be welded with 2209 filler wire.
The two types of welds are?
TIG uses tungsten in a gun and electricity to melt the material, the user must manually add filler rod. Needs shielding gas Mig uses a gun, but the filler rod flows out of the gun. Electricity flows from tip of wire into material. needs shielding gas except with flux-cored wire. SMAW uses pre fluxed electrodes. electricity flows trough electrode holder, into material when material is scraped by electrode. No shielding gas. Oxy-fuel. Flame welding. Oxygen and a fuel (acetylene, propane, mapp, etc.) are mixed in a torch, ignited, and used to melt material. filler wire is manually added. There are more indepth explanations, and advanced machines, but that is the basics.
What are homogenous heterogenous and autogenous welding processe s?
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.

What filler metal is used to weld 316 to Monel 400?
You would use 316 as the filler, it is the more pertinent metal of the two.
What filler metal is used to weld inconel 625 to stainless steel?
inconel
