| Welding Process / Form: | |||
| Your choices are... | |||
| Cutting / Gouging Electrode | Cutting or gouging electrodes are used. | ||
| Flux Coated / Stick | Flux coatings are applied to stick welding electrodes, and to brazing rods or strips. Stick electrode welding or shielded metal arc welding is a common welding process. The flux covering the electrode melts during welding or brazing to forming a gas, which then shields the arc and molten weld pool. The flux also forms a slag that protects the cooling weld pool or braze joint. The slag must be chipped or brushed off the weld bead, however. Flux coating also provides a method of adding scavengers, deoxidizers, and alloying elements to the weld metal. | ||
| Flux Cored Wire | Flux cored wire welding is similar to MIG welding, but uses a flux-filled central core. Most MIG welding equipment can perform flux-cored, arc-welding processes. With flux cored arc welding, the flux eliminates the need for a shielding gas supply. Metal and filler metals with an arc are struck between a consumable metal filler wire and the base alloy workpiece. The metal filler wire or consumable electrode is fed continuously and fused with the workpiece. Brazing rods are also available in flux cored forms. | ||
| MIG Wire (GMAW) | Gas metal arc welding (GMAW) is also known as the metal inert gas (MIG) process. In turn, MIG welding is sometimes referred to as short circuit transfer. With MIG arc welding, metal is joined by melting the base and filler metals with an arc struck between a consumable filler metal wire and the base alloy workpiece. The filler metal wire or consumable electrode is fed continuously fused with the workpiece. An externally-supplied gas or gas mixture provides shielding. Normally, MIG welding does not transfer any metal across the arc. Metal is deposited only when the wire actually touches the work. | ||
| Powder | Products are powders. | ||
| Solid Wire | Products are solid wires. | ||
| Strip / Sheet / Foil | Products are strips, sheets, or foil. | ||
| Thermite Mix | Products are thermite mixes. | ||
| TIG Rod (GTAW) | Gas tungsten arc welding (GTAW) is known also as tungsten inert gas (TIG) rod welding. TIG welding joins metals by melting base and filler metals with an arc struck between a tungsten electrode and the workpiece. Normally, the tungsten electrode does not become part of the completed weld. Typically, filler metal is used. Argon inert gas or inert gas mixtures are used for shielding. | ||
| Tubular Wire | Products are tubular wires. | ||
| Weld Stud / Fastener | Studs, nuts, or other fasteners are designed for welding to a workpiece. The fastener becomes an integral part of the welded assembly. Special welding guns, power sources, and systems may be used in the stud welding process. | ||
| Weld Insert / Backing Ring | Products are weld inserts or backing rings. Weld inserts and backup rings provide several functions such as setting the gap properly aligning or positioning the weld joints , preventing excessive weld root bead (produce smooth root beads) , insuring complete penetration through the weld joint and providing the consumable filler alloy material required. A good weld insert allows smooth tying in of pipe or tube, insert and adjacent fitting, tube, valve or pipe. Weld inserts are produced in coiled, preformed backing ring and solid backing ring forms. The cross sections of the weld inserts are available in several different configurations such as "J", inverted "T", "K" or rectangular shapes. Backing rings can have a performed round, square, rectangular or custom shapes. | ||

| Steel - Carbon | Filler alloys are used for welding carbon steel alloys. These metals include plain carbon, low carbon, and mild steel. | ||
| Steel - Low Alloy Carbon | Filler alloys are used for welding low alloy carbon steel, a metal that is known also as high-strength low alloy (HSLA) steel. | ||
| Steel - Stainless | Filler alloys are used for welding stainless steel alloys. These metals include ferritic (400 series), austenitic (300 series), and other types of stainless steel alloys. | ||
| Steel - Tool / High Alloy | Filler alloys are used for welding tool or high alloy steels. These metals include high speed, hot work, die, shock, air, and oil or water grades. | ||
| Hardfacing / Repair Alloy | Specialized filler alloys are used to join castings, or produce or restore a specialized layer of a work surface. Usually, these filler alloys are highly alloyed to develop required properties. Several variations exist. Proper selection depends upon the application, such as build-up or joining, overlay, high abrasion resistance, high impact and abrasion resistance, and corrosion and heat resistance. Build-up filler alloys are used for repairing or joining castings or cast iron components. | ||
| Titanium Alloy | Filler alloys are used for welding titanium or titanium alloys. | ||
| Zirconium Alloy | Filler alloys are used for welding zirconium or zirconium alloys. | ||
| Other | Other unlisted, specialized, or proprietary metals or alloys. | ||

| |||
| Low Hydrogen Alloy? | Low hydrogen filler alloys are designed to hydrogen embrittlement or hydrogen-assisted cracking in welded steel components. The moisture contamination of electrodes or post-electroplating may also result in hydrogen embrittlement. A low temperature heat treatment of the steel product eliminates the problem on smaller parts. | ||
| Search Logic: | "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice. | ||
