The biggest deposit of chromium in the world is Bush weld igneous complex in south Africa.
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
yes because the zinc melts and causes it to weld

Argon is used in welding to prevent oxygen from entering the weld site. Oxygen is basicly bad for the weld and Argon displaces the oxygen which results in a better weld (less heat stress, less air pockets (imperfections in the weld) etc.)
The biggest deposit of chromium in the world is Bush weld igneous complex in south Africa.
At first, the area of cross section of the weld, length of the weld, volume of the weld in cubic inches, weight of weld in cubic inches. To express in formula: Weight of Weld Metal = _ Êx ÊBase Êx ÊHeight Êx ÊLength Êx ÊWeight of Material.
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.
Full penetration.
Porosity is the formation of bubbles in the weld.
Tig is always done in straight polarity, i.e. electrode negative. reason: almost 2/3rd of the heat is generated in positive terminal of weld, in this case the base metal and the rest in the negative terminal, in this case the tungsten electrode. Also you don't want to deposit the tungsten electrode in the weld, do you?
seam welding is a process that produces a weld at the faying surfaces of two similar metals where its used depends on which metal you look to weld
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
Depends on what you are welding, but generaly welds can meet, or even weld on top of a weld.

A TCU4a weld is a Corner Jount (TC), Unlimited Thickness Full Joint Penetration (U), Single Bevel Groove (4), and (a) is the welding process.
