    Automated welding redefines industrial productivity

    Innovation is once again at the forefront of the metal fabrication sector. GOSAN, an international benchmark for lifting solutions, has taken a decisive step into the future thanks to ARCUS project, which significantly increases the productivity of automated arc welding in its production cells.

    The result is a true paradigm shift: faster, more productive and cost-effective processes, reinforcing the company’s position as a leader in technology applied to industry.

    A revolution within the plant

    The implementation of the innovative HW-GMAW (Hot Wire-Gas Metal Arc Welding) technology, validated and certified in GOSAN production centres, allows the incorporation of a second hot wire in each robotic arc welding cell. This increases productivity, eliminates downtime and ensures a level of repeatability and uniformity that would be impossible to achieve with manual processes.

    This integration makes a difference in welding automation, achieving maximum productivity with continuous cycles, higher deposition volume and zero human fatigue.

    • Quality assured: consistent seams, full traceability and fewer defects.
    • Eefficiency and cost-effectiveness: optimisation of consumables and energy consumption thanks to automation.

    With ARCUS, GOSAN is strengthening its commitment to innovation and operational excellence, consolidating a more efficient, reliable and competitive production model in the global market.
