Resistance welding

Indisputable advantages

Resistance welding is a hot assembly process using the electrical resistance of the metal parts. It’s a well-established technology, used by many industries because of its economical and technical advantages. Parts welded by resistance have a very long life-time and are indestructible.

The resistance welding process includes sub-families like : Compacting, Combrazing, Hot-crimping, Resistance brazing.

  • Reduced operating costs : The simplicity of the resistance welding process helps reducing operating costs. Fewer components and greater efficiency translate into savings in resources, which is particularly advantageous for companies looking for spend optimization.
  • Material adaptability : This welding method is compatible with a variety of materials, whether steel, copper or other alloys. The ability to adapt to various material combinations makes it a versatile option, enabling manufacturers to meet a multitude of design requirements.
  • Process cleanliness : Resistance welding eliminates the need for welding flux or shielding gases, reducing the risk of contamination. This process cleanliness is crucial in industries such as aerospace and electronics, where precise, impurity-free welds are essential.
  • Fast and efficient : Resistance welding is renowned for its speed. By harnessing the electrical resistance of the metals to generate heat, it enables fast and efficient welds. This characteristic makes it an ideal option for production lines where productivity is essential.
  • Strength and Safety : Resistance welding results in strong, visually flawless connections without damaging the metals, ensuring safety and reliability.
  • Precise heat control : This technology ensures precise control of the heat applied during the welding process. Operators can adjust parameters to suit specific material properties, minimizing thermal distortion and ensuring high-quality welds.
  • Weld durability : Resistance welds are often remarkably durable. The molecular structure of the weld is solid, offering high mechanical strength. This durability makes it a choice option for demanding applications where weld strength is crucial.
  • Reducing waste and environmental impact : The simplicity of resistance welding helps minimizing production waste. Fewer consumable materials and fewer rework operations mean less environmental impact, which is increasingly important in today’s context of sustainability.
