In this work is presented a comparison between Pulsed MIG and Short-circuit MAG processes concerning economical and operational aspects. A systematic experimental procedure was carried-out so that the response to variation of travel speed, mean current and contact tip-to-work distance could be assessed within the same range. The operational envelopes were built taking into account lack of fusion and lack of penetration. Deposition rate and deposition efficiency were raised to evaluate productivity. The results showed that short-circuit MAG has a broader operational envelop than Pulsed MIG, but the latter, despite the narrower range, provides more productivity.
