What is Electrode Welding? - Fronius International
In principle, almost all materials can be welded using electrode welding. The process is mainly used in steel and pipeline construction, but is also used in metal trade and industry. Manual metal arc welding allows for any type of weld seam and position, irrespective of whether this involves restricted or overhead positions, vertical up seams or vertical end welding.

MIG Welding vs ARC Welding - Most Inside
The consumable MIG welding wire and the electrode don’t deal with rusts, dirt, stains, corrosion, and other contaminants on the metals you want to join. It made MIG welding process mandate pre-cleaning step where you’ll have to manually remove the rust, stains, and other contaminants before start welding.

Why TIG Welding Is Better Than MIG Welding
TIG welding can achieve this level of precision because the operator has more control over the gun vs. MIG welding. Unlike the MIG gun, which contains both the electrode and filler metal in one system, TIG welding uses a non-consumable tungsten electrode to form the arc.

Key Rules on Welding Angle, Direction, and Speed
For wire (flux-core or MIG) welding, keep a work distance of ⅜ to ½ inch. With stick welding, look to keep that distance ⅛ inch between the rod tip and work piece. “The arc length should not exceed the diameter of the core of the electrode,” Leisner says.
Stick Vs. Wire Welders | Grainews
Wire welding replaces the fixed-length stick electrode, which must be replaced frequently, with a spool of wire fed through a welding gun. Because the wire is fed at a continuous rate, you don’t need to keep moving your hand closer to the weld as the stick burns off.
As an example, they presume that by welding a base metal of Type SAE 4130 (chrome moly steel) with an electrode with a Type SAE 4130 steel core wire, the weld deposit will match exactly the base metal and the weld will perform identically to the base metal.

4/7/2020· MIG welders generate a wire welding electrode on a spool that is automatically fed into the welder at a uniform speed. An arc is generated with the help of the electrical current that flows between the base metal and the wire.
Difference Between Consumable and Non-Consumable …
In some arc welding processes, the electrode is consumed during welding to supply necessary filler; while in other processes, the electrode remains unaffected. Based on the consumption of electrode material during welding, welding electrodes can be classified as consumable electrode and non-consumable electrode.
