Resistance welding electrode selection is one of the challenges when starting out in Resistance welding. Electrode materials vary and include Copper, Tungsten, and Molybdenum; as well as various alloys of each of the above materials. Electrode size and shape are important factors in achieving the weld spot that you would like. What Does RWMA Mean?
On a large firewater system for an offshore platform, orbital welding was able to reduce welding time to one half that of manual welding and cut reject rate from 15% to 5% The joint design tolerances must be tightly controlled and are crucial for successful orbital welding. The recommended joint design for most pipe sizes is a J-groove with a

Pure helium or high percentages of helium (He-90%, Ar-10%) shielding gas are used primarily for gas tungsten arc machine welding with direct current electrode negative (DCEN). Often designed as seam welders, the coination of GTAW - DCEN and the high heat input from the gas used can provide fast welding speeds and outstanding penetration.
Material Selection. For quite some time, tungsten manufacturers have added an oxide to pure tungsten to improve the arc starting characteristics and the longevity of pure tungsten electrodes. Below is a chart that lists the major commercially sold tungsten types, their American Welding Society (AWS) and International Standards Organization (ISO

Carbon Dioxide (CO2) is a tasteless, colorless, odorless, nonflammable gas. It is commonly utilized with argon (Ar) as a shielding gas during welding or in some cases it is used in pure vapor state. This prevents atmospheric contamination of molten weld metal during gas shielded electric arc welding process. Helium. GENERAL FACTS:
Welding alloys are also designed for specific welding processes. Each welding process may require a specific alloy form; e.g. stick or wire, and may require a flux core or coated flux to isolate the weld. Common welding processes include: Stick electrode welding or shielded metal arc welding (SMAW) is a common welding process. The flux covering

Aluminum Weld. For welding aluminum, Argon gas is mainly used materials as it is very sensitive to contamination and it pure argon helps to produce better results while marrying aluminum, but it is also important to remeer if the aluminum material is more than half an inch thick, it might be a good idea to have some Helium (25%) added to the mix to produce optimal results.

World class welding wire for critical appliions. United States Welding Corporation is a recognized leader in the welding industry of filler metal development since 1960.Improvements in the reliability of repair welding and increased use of “recycled” gas turbine components have been accomplished by specifying lower trace elements and vacuum melting in Aerospace Material Specifiion (AMS).
MIG and Flux-Cored Wire In Gas Metal Arc Welding (GMAW), you won''t be using a stick electrode or a filler rod. Instead, everything you need to deposit a weld comes from a spool of metal wire. In this welding process, more popularly known as MIG, a tank of gas (typically CO2 or argon) provides the shielding while the wire melts into the base metal.
For thinner metals and jobs performed out of the wind, solid wire electrodes can work quite well. Solid wire electrodes used in MIG welding are not as portable as flux-cored wires. This is due to the necessity of a shielding gas in MIGW. Both solid wire electrodes and flux-cored wire …

ERTi-2 (Commercially pure) Titanium is a TIG, MIG and submerged arc filler metal used for welding commercial pure titanium alloys commonly found in appliions requiring high temperature resistance and resistance to chemical reagents. Although there are four grades of Commercial Pure Titanium filler metals, C.P. Grade 2 (ERTi-2) is the most popular because of its good balance of strength
Selection of a welding process may also be affected by the availability of consumables. For example, for welding a specific aluminium alloy it may not be possible to acquire appropriate flux-cored wire thus limiting the use of FCAW process. Easy availability and regular supply are essential for un-interrupted use of the process and therefore
