The Art of Narrow-groove Welding
Narrow-groove (NG) welding is defined, in part, by the American Welding Society (AWS) as “a variation of a multiple-pass welding process with filler metal, using a small root opening and a V-groove with a small groove angle”. This yields a weld with a high ratio of depth to width. Narrow-groove welding techniques are well-established for […]

Material Properties for Arc-Based Additive Manufacturing of Ti 6-4 ELI
An area where EWI is expanding its knowledge is in characterizing and cataloging mechanical properties of additively manufactured metals (metals AM). The work described here was performed to obtain baseline mechanical property data for Ti 6-4 ELI weld metal buildups that were produced using hot-wire gas tungsten arc welding (GTAW-HW). The equipment used to weld […]

Arc Welding Aluminum at High Speed
Gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW) are both regularly used for welding aluminum. GTAW is a slow process when compared to GMAW and GMAW is typically used when extremely high weld quality (with respect to porosity) is not required. GMAW works well for welding aluminum in structural, automotive, or thick […]

Get it Right – It’s Movember!
Well folks, Movember is upon us. Some of you call this no-shave November and use it as an excuse to grow a beard or a goatee or something like that. It is officially called Movember and growing a sweet moustache is the proper way to raise awareness and money for men’s health issues. Prostate cancer […]

Increasing Productivity with Submerged Arc Welding
Submerged arc welding (SAW) is a high deposition rate process when compared to gas metal arc welding (GMAW) or gas tungsten arc welding (GTAW). Certain applications such as large flat panels, girth welds in pipe, or spiral pipe mills can benefit from techniques used to increase the deposition rate, and consequently, the productivity of the […]

Cladding with Plasma Arc Welding (PAW)
Plasma arc welding (PAW) is very similar to gas tungsten arc welding (GTAW). If you look at the schematic shown in Figure 1 you can see that the arc in PAW is created between a non-consumable tungsten electrode and is constricted by passing through an orifice. This provides a more columnar arc with a higher […]
