Exothermic Electrodes: Cutting Techniques, Cast Iron, Stainless Steel, and Non-Ferrous Metals.

Cast iron, stainless steel, and non-ferrous metals do not oxidize; therefore, underwater cutting becomes a melting process. The exothermic process develops tip temperatures in excess of 10,000 degrees F, which is sufficient to melt these materials with ease. The following technique is recommended: a. Keep the tip firmly buried in the puddle. Using a sawing … Read more

Trouble Shooting Exothermic Electrodes

Oxy-arc cutting, especially exothermic cutting relies on an unobstructed oxygen flow to be most effective. With inadequate oxygen flow, the rod will burn but not produce the desired cutting effect. Since the actual cutting result is derived from the volume of oxygen reaching the target, any restriction in oxygen flow will decrease efficiency. Symptoms. The … Read more

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… Underwater Shielded Metal Arc Welding … Read more

Types of 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. The composition of the electrode coating determines its usability, as well … 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

Oxygen Arc Cutting Steel-Tubular Electrodes

The oxygen arc cutting steel-tubular electrode consists of a steel tube with a waterproofed flux coating which is applied during the manufacturing process. The electrode is 14 inches long with a 5/16-inch outer diameter and a bore diameter of slightly less than 1/8 inch. The waterproof flux coating is similar in composition to the coating … Read more

Exothermic Electrodes

The BROCO Ultrathermic electrode consists of seven small rods inside a thin steel tube. One of the seven rods is a special alloy that will burn independently after an arc is struck and oxygen is flowing through the tube. The remaining six rods are made of mild steel. The electrode is insulated with electrical tape. … Read more
