Gas Tungsten Arc Welding Gas Metal Arc Welding Flux Cored Arc 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.
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 .
Gas welding basically used for weaker joints(in sheets) and arc welding for stronger one(plates). mobile welding (not in a shop)is the ideal time for arc welding . gas welding is the way to go as far as production is concerned , but requires environment with little air circulation or wind , plus gas bottle , machine , and a short lead , which makes it ideal for shop work answer Gas welding - generally use for welding of thin plates/pipes. Less heat input and less likely to burn off the edge of the plates (undercut). It is a more expensive process because of gas shielding. Arc welding - use for thicker plates usually with larger size electrodes. Higher weld production rate. Shielding by means of electrode coating.

Larger in Gas Welding. In all arc processes the HAZ is concentrated in a couple inches around your bead. In gas welding it can be double or triple that size.
Gas Tungsten Arc Welding Gas Metal Arc Welding Flux Cored Arc 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.
Argon is the most common gas used in gas metal arc 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.
The gas acts as the flux would, in shielding the molten steel from the oxygen in the air.
Carbon Dioxide iswidely used for MIG welding but I never heard of carbon monoxide and it is definitely not used in the industry as shielding gas. The purpose of the shielding gas is not just shielding the weld pool but offer arc stability with an adequate ionization potential. The heat and electrical conducctivity of the gas at the arc temperature are a huge factor as well.
No, that would defeat the purpose. Shielding gases must be inert (e.g. argon, helium).
Carbon dioxide, Argon, Helium, but not Nitrogen, can be used as 'shielding' gas in Gas Metal Arc Welding.

These inert gases are used in gas tungsten arc welding, and also in gas metal arc welding for the welding of non-ferrous metals. Semi-inert shielding gases, or activeshield gases, include carbon dioxide, oxygen, nitrogen, and hydrogen. These active gases are used with GMAW on ferrous metals.
