By observing the four basics. Correct/consistent travel speed. Correct amperage setting. Correct/consistent arc length. Correct electrode angle.
Silicon is used to lower the viscosity of the weld puddle. This allows better flow of the molten weld puddle.
mig welding is Metal Inert Gas welding. it typically uses Constant voltage DC+ current. It uses a wire feeder that supplies the electrode to the weld puddle and shields the molten weld puddle with inert gas (argon/co2 blend). Filler wire and shielding gas depend on the metal being welded.
Welding is fusing two metals together. Welders do the welding. Welding is the melting of two metals and also sometimes the addition of extra metal to make up for shrinkage that occurs in the process. With "heat" caused by gas or electricity or both the welder creates a small pool of melted together surfaces and then moves this small puddle in circular or "S" shaped patterns until the weld is complete. Controlling the heat and puddle is crucial to good penitration and thusly a good weld. welders do not "glue" the two surfaces together, they melt them.
Actually I usually crowd the puddle when welding vertical up. The longer the arc length the more the arc can wander.
Yes .... but most welds will not be as good as those using flux. SMAW with bare electrodes produces poor results. GTAW and GMAW are done without flux when an inert gas is used to protect the puddle. Some Oxy-fuel welding can be done with out it. In most applications flux is used not only to protect the molten puddle but also add ingredients to the weld.
Wind! By disrupting the protective atmosphere around the puddle provided by the shielding gas.
When welding on AC on a TIG welder you have to option to adjust how your arc passes from your torch to your metal and vice versa. This allows you to clawed your puddle clean of contaminants or burn your weld deeper while welding. When set on balanced, the arc equally passes in both directions.
Welding rods are fillers that add to the molten pool of metal. They are usually stronger than the metals being fused. In arc welding, they have a coating that burns and creates a shield around the puddle. welding rods are used for weld two pieces of metal together, or to cut metal if you have big enough rods and enough amps.
Shielded Metal Arc Welding, commonly called Stick welding. A shielded electrode passes a current between itself and the workpiece. Both the base-metal and the electrode are melted by the current and the electrode is consumed and deposited into the melted puddle forming the weldment.
Maybe maybe not. The gas has to flow to the weld area to protect the weld puddle. This may be what is happening. If you have a long cable to the gun this is a good feature. Check with a welding rep/salesman from your local welding supplier.
To my knowledge there is no process called Argon Welding. Argon is an inert gas used to protect the weld puddle when using the GTAW (TIG/Heliarc) and GMAW (MIG) process. Almost all welding processes utilize electricity. OAW (Oxy-Acetylene now called Oxy-Fuel) being the exception.
Flux means to clean The flux becomes liquid, mixes with the molten puddle, picks up impurities and floats them to the surface.
