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 is weld log?
A weld log is a Quality Managment tool that acts as a database used to keep an ongoing record of welds made during construction fabrication type projects. The Weld log is used to record Important information recorded as "weld number" Welders Stencils", "Weld Procedure", "Weld Type" Material Type" "Project#" and any other important information to ensure the traceability and Quality Assurance of each welded junction during fabrication or repair activities. The best example can be found here: http://sites.google.com/site/masterweldtracker/
What is girth weld?
circumfrencial weld is sometimes referred to as Girth weld. its just another term.
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.
Who is better astm a 105 or astm 197?
ASTM A105 is a Carbon Steel material spec used in forged fittings, such as 2000# or higher socket weld or threaded fittings, forged flanges, etc.. ASTM A197 is a Malleable iron material spec used in 150# socket weld or threaded fittings.
What inches you can weld with one electrode?
It varies from 3 inches to 13 inches. The electrode type, type of weld, and position of weld all determine how far you can get done with a single rod
What welding process is used to weld cast iron?
arc welding such as SMAW (stick), GMAW (mig). Some cast metals may be brazed for certain applications. The actual properties of the Cast metal will be needed for the type of electrode and/or process.
Three condition of electrode that could affect weld bead shape in sheilded metal arc welding?
The angle of the electrode, the speed of the electrode used to weld and the size of the electrode.
How can you weld the pump case which is made with cast iron?
== ==
What is a leading electrode angle for in welding?
what characteristics does the weld bead have when weaving the electrode
One should never cut or weld directly against?
You should not weld on concrete, as it can explode if heated
What characteristics of the weld bead does the weaving of the electrode cause?
motion of the electrode causes different pattterns in th formation ofthe cooling weld puddle. You can alter the weld patter by changing the electrode motion,,ex: motion straight across the weld zone and dropping electrode position say (1/8th inch) produces given pattern..same pattern with a slight upward motion at edges of weld zone another pattern...etc etc
What electrode is mainly used for a root pass in structural steel applications?
Usually the same type that is used for the rest of the weld.
If electrode use in welding has moisture what effect will it have on the weld?
Electrodes with too much moisture may lead to cracking or porosity.
Which electrode is using for cs and ss combination weld?
309l
What is a straight weld bead on the surface of a plate with little or no side to side electrode movement called?
A narrow, straight weld bead that is created by moving the SMAW electrode straight along the weld joint. A quality stringer bead should have good tie-in on both sides of the weld.
What metal is not used to weld the gas tungsten welding process?
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.
