As global metal consumption continues to soar—reaching a staggering 1.8 billion tonnes in 2020 alone—the need for efficient metal reclamation has never been more critical.
Welding, with its ability to transform worn and damaged components, makes it an essential solution to conserving and extending the life of metals and assets.
As a high-quality process, brimming with opportunity, welding is set to shape the future of sustainable metal reclamation in Australia.
In this blog, discover the various welding techniques, the benefits of welding and role that it plays in supporting the circular economy, plus the technological advancements that’s forecasted to change the industry.
The Welding Process: A Cornerstone of Metal Reclamation
Welding plays a pivotal part in revitalising metal components that might otherwise be discarded.
Each technique brings its unique strengths to the reclamation process:
- MIG welding, with its continuously fed wire electrode, offers efficiency and less scrap material, making it ideal for production-scale reclamation projects.
- TIG welding, while slower, provides precision that’s invaluable when working with delicate or complex metal components.
- GMAW shines when dealing with galvanised steel and recycled metal scraps, offering versatility in various reclamation scenarios.
The choice of method depends on the specific needs of each project. Our team of skilled surface engineers, carefully assess each component to determine the most suitable approach.
Preparation: The Key to Successful Metal Reclamation
Before any welding can begin, proper preparation is crucial. This involves thorough cleaning to remove any contaminants, precise cutting to shape the metal as needed, and careful assessment of the material’s condition.
Following standardised welding procedures and specifications is essential to our process. This commitment to quality and safety ensures that every reclaimed metal component is not just functional, but reliable and durable.
The Benefits of Welding in Metal Reclamation
The environmental and cost benefits of metal recycling contribute to a more sustainable future:
1. Waste Reduction: Repairing and repurposing metal objects significantly extends their lifespan, keeping them out of landfills.
2. Energy Conservation: Reclaiming metal through welding consumes far less energy compared to producing new components from raw materials.
3. Resource Preservation: By reusing existing metal, we reduce the demand for mining and processing of new ore.
4. Cost Efficiency: Businesses benefit from substantial cost savings by reclaiming and repairing components rather than replacing them entirely.
5. Supporting the circular economy: Welding enables the repair, refurbishment, and repurposing of components, supporting the ‘reduce, reuse, recycle’ principle. By extending material life and minimising waste, welding helps transform our economic model from linear to circular.
Real-World Impact: Extending Equipment Life Through Welding
A recent project with Mecfab Enterprises illustrates the power of welding in metal reclamation. A hoist, crucial for airport ground support, had suffered significant wear over time.
Our solution involved redesigning worn components, upgrading materials and performing extensive welding repairs.
By grinding out cracks, rewelding affected areas and installing new parts, we restored the hoist’s integrity.
This project demonstrates how welding contributes to extending the life of critical industrial equipment and providing a more sustainable option.
