What is shielding gas arc welding?
shielded metal arc welding does not required any shielding gas
What are the 5 different types of welding?
There are far more than 5 types or processes of welding. Currently the American Welding Society (AWS) states that there are more than 80 different welding and joining processes. However, some of the common welding processes include shielded metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), flux cored arc welding (FCAW), and oxyfuel gas welding (OFW).
How can you keep the arc from spattering as you weld?
for mig welding spatter can be reduced by amp, voltage and wire speed adjustment. check shielding gas. stick welding check the recommended voltage, amps and application for the rod you are using keep your arc short. tig welding, be sure you are using the proper tungsten, and shielding gas and filler rod for the metal you are welding, don't dip the tungsten. make sure the metal you are welding is clean .
What are the variable parameters for TIG welding?
The variable parameters for gas tungsten arc welding (GTAW) include; current, arc length, electrode type, electrode size, electrode grind angle, shielding gas type, shielding gas flow rate, and travel speed.
How do you troubleshoot the porosity blow holes burnthrough problems in CO2 MIG welding?
Check the shielding gas & its flow rate.
What is shielding gas arc welding?
shielded metal arc welding does not required any shielding gas
What does oxygen have to do with welding?
Oxygen is an atmospheric gas that is unwanted in almost all welding processes because in it's molten state, metal oxidizes very easily and causes a weak joint. Weld surfaces are protected during the welding process to keep oxygen from contaminating the weld either by a shielding gas, flux, or in torch welding, the torches own exhaust. Occasionally however, oxygen may be added to the shielding gas mix in small amounts to stabilize the arc and reduce undercutting.
What is a welding lead?
the welding lead is the cable coming from the welding machine that either feeds the wire and shielding gas (mig) or or provides current to the electrode through the holder
What happens when argon is burnt?
Argon won't burn. It is used in industrial processes like welding and metal smelting as a shielding gas. Some of those processes will heat the argon to 10,000 degrees Fahrenheit, and it doesn't burn. WRONG Henry Cavendish died when he heated Argon
Definition of argon welding?
A.K.A. Gas Metal Arc Welding -- Semi-automatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas are fed through a welding gun.
Which of the processes joins metals plasticaliy in welding?
The solid-state welding processes. This can include friction and friction stir welding where the base metal never reaches its melting point.

Is O2 also added to shielding gas in tungsten arc welding process?
No, that would defeat the purpose. Shielding gases must be inert (e.g. argon, helium).
What are the ten difference between TIG and MIG welding processes?
ElectrodeTIG welding uses a tungsten electrode that is not consumed during the welding process. MIG welding uses a metal electrode that doubles as filler material for the weld and is consumed during welding.Shielding GasTIG welding primarily uses argon as a shielding gas, with helium occasionally used. Argon is also the primary shielding gas used in MIG welding, but argon mixtures and carbon dioxide are often used for different applications.Filler MaterialTIG welding requires a separate filler material in rod or wire format because the electrode is not consumed. MIG welding delivers the filler material via the electrode.Work Piece MaterialsTIG welding can be applied to just about any metal, from steel to aluminum and exotic alloys. MIG welding was developed for nonferrous metals, but can be applied to steel.DifficultyTIG welding is considered to be more difficult than MIG welding because tighter tolerances have to be maintained between the electrode, the filler rod and the work piece.

Can you prevent parts from being magnetized during resistance welding?
The only way to prevent parts from being magnetized during resistance welding is by using the process of magnetic shielding. With the shielding process, objects are surrounded with material to generate a flow that avoids the opposite poles from becoming magnetized.
