When using a consumable-electrode process such as gas metal arc welding (GMAW) or submerged arc welding (SAW), the three primary process variables are arc current, wire feed speed (the rate at which the consumable electrode is fed from the welding torch), and arc voltage. Current and wire-feed-speed cannot be varied independently. To maintain the same […]
Read MoreSubmerged 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 […]
Read MorePlasma 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 […]

Read MoreEWI has capability in high productivity strip cladding. If you desire an increase in productivity, strip cladding may be a solution for you. There are two variations of strip cladding, submerged arc and electroslag. Electroslag strip cladding (ESC) can achieve deposition rates of over 75-pounds-per-hour when using a 60-mm wide strip. Compare this to submerged […]
