Reciprocating Wire Feed GMAW – An Advanced Short Circuit GMAW Mode

Reciprocating wire feed gas metal arc welding (RWF-GMAW) is a low heat input, precisely controlled variation of the GMAW process.  With the RWF-GMAW process the wire is reciprocated in and out of the weld pool.  The wire motion is synchronized with the current waveform to produce a weld that is characterized as having minimal if […]

GTAW for Additive Manufacturing of Ti 6-4 Components

Components made from titanium are candidates for additive manufacturing due to both the high material cost and the long lead times on material purchases.  Electron Beam Freeform Fabrication (EBFFF) is the most widely used method for additive manufacturing of large scale titanium parts.  This process is well established but is expensive and requires the parts […]
