Welding Electrodes & Filler Metals

Tungsten Electrodes Tungsten Electrodes Non-consumable tungsten electrodes for GTAW (Gas Tungsten Arc Welding) or TIG (Tungsten Inert Gas) welding, generally are of several types. Tungsten electrodes types and their typical application can be identified by color-coded end marks as follows. Pure Tungsten: Green 2% Ceriated : Gray 2% Thoriated: Red… Tungsten Electrode Selection Tungsten Electrode … Read more

Arc Welding Electrodes

Arc Welding Electrodes. When molten metal is exposed to air, it absorbs oxygen and nitrogen, and becomes brittle or is otherwise adversely affected. A slag cover is needed to protect molten or solidifying weld metal from the atmosphere. This cover can be obtained from the electrode coating, which protects the metal from damage, stabilizes the … Read more

Tungsten Electrode Selection

The selection and preparation of tungsten electrodes for TIG Welding or Gas Tungsten Arc Welding (GTAW) to use for a particular application depends on many variables, including the type of material to be welded, the welding amperage, and the type of weld, among other factors. Tungsten Electrode Diameters And Lengths Tungsten Electrodes are available in a variety of … Read more

Flux-cored Arc Welding Electrodes

The electrodes used for flux-cored arc welding provide the filler metal to the weld puddle and shielding for the arc. Shielding is required for sane electrode types. The purpose of the shielding gas is to provide protection from the atmosphere to the arc and molten weld puddle. The chemical composition of the electrode wire and flux core, … Read more

Solid Electrode Wires

Bare or solid electrode wires are made of wire compositions required for specific applications and have no coatings other than those required in wire drawing. These wire drawing coatings have a slight stabilizing effect on the arc but are otherwise of no consequence. Bare electrodes are used for welding manganese steels and for other purposes … Read more

Non-Consumable Electrodes and Other Filler Metals

There are other filler metals and special items normally used in making welds. These include the non-consumable electrodes (tungsten and carbon), and other materials, including backing tapes, backing devices, flux additives, solders, and brazing alloys. Another type of material consumed in making a weld is the consumable rings used for root pass welding of pipe. There are … Read more

Arc Welding Electrode Classification System

The SMAW electrode classification code contains an E and three numbers, followed by a dash and either “15” or “16” (EXXX15). The E designates that the material is an electrode and the three digits indicate composition. Sometimes there are letters following the three digits; these letters indicate a modification of the standard composition. The “15” or “16” … Read more
