POSCO
Innovative PosZET® Welding Technology for Eco-friendly/ Lightweight/ Cost-effective Auto Parts
As a company, POSCO offers products and solutions that help to mitigate direct and embedded carbon emissions. The company’s solutions are designed to reduce total GHG emissions across the life cycle of a product through direct reduction of the carbon footprint and also by offering positive tools, or handprint solutions, which will help users of products and solutions to reach their own sustainability goals.
PosZET® is a handprint solution offered through our proprietary welding technology. When applied, this packaged steel and welding technology produces eco-friendly, lightweight, and cost-effective automotive parts.
A leading benefit of PosZET® is that the weight of parts is made lighter owing to the enhanced durability of the welded parts, resulting in reduced steel gauge and weight. Additionally, the parts manufacturing process is made more sustainable and cost-efficient.
First, because PosZET® technology enhances welding efficiency and productivity, less power and heat are required, thereby improving part durability and reducing total CO2 produced per component manufactured. Secondly, acid descaling, a key pre-treatment process that improves the welded part’s resistance to corrosion, can be omitted, helping to prevent emissions and to save production costs. Finally, PosZET® is immediately applicable in existing facilities; hence, customers can benefit from instant impact without the burden of heavy CAPEX.
POSCO has launched PosZET® GIGA, a welding technology customised for giga steel that offers unrivalled performance. Nissan, a global OEM, recently approved PosZET® GIGA for use in its new vehicle, underscoring its quality and cost-effectiveness.
Finally, PosZET® aligns with the company’s corporate vision to be a leading global provider of eco-friendly future materials; hence, it has been introduced as a key milestone in the company’s sustainability report and featured in the scientific journal Nature Communications.
With the demonstrated benefits of this welding technology, the goal is to pioneer future handprint solutions in and beyond the automotive industry.
