Triple 7 is designed for the semi-automatic gas-shielded welding of carbon steel and some higher strength steels where requirements and conditions do not exceed its capabilities. It is intended for single–and multiplepass welding in all positions and has a fast-freezing slag that permits the welder to use higher current to deposit more metal faster and still produce a flat bead in all positions. The slag removes easily even from deep groove weldments and spatter is low, so a welder spends more time welding and less time cleaning up. The X-ray quality surpasses the radiographic specifications of AWS A5.20 and ASME SFA 5.20 when welded with the recommended procedures. Typical applications include shipbuilding, railcar fabrication, general plate fabrication, heavy gauge sheet metal, pressure vessels, and certain pipe weldments. shipbuilding, railcar, general plate fabrication Industries
