How to Do Aluminium Foil Welding? | HAIFEI Aluminium Diffusion Welding Machine

Описание: How to do aluminium foil welding is a common challenge in advanced manufacturing industries such as EV batteries, energy storage systems, power electronics, and lightweight electrical components.
In this demo, we introduce the HAIFEI aluminium diffusion welding machine, a professional solution designed to achieve stable, high-quality aluminium foil welding without deformation, delamination, or weak bonding.

Aluminium foil welding is particularly difficult due to aluminium’s high thermal conductivity, low melting point, oxide layer formation, and thin material structure. Traditional welding methods often lead to foil burn-through, uneven bonding, surface oxidation, or poor joint strength, especially when dealing with large-size or multi-layer aluminium foil.

🔬 Why Diffusion Welding for Aluminium Foil?

Diffusion welding is a solid-state joining process that bonds materials under controlled temperature, pressure, and time, without melting the base material. This makes it an ideal solution for aluminium foil welding, as it eliminates thermal shock and minimizes the risk of material damage.

The HAIFEI aluminium diffusion welding machine ensures:

Uniform pressure distribution over the aluminium foil

Accurate temperature control below the melting point

Solid-state metallurgical bonding without filler material

Clean joint surfaces with minimal oxidation

As a result, the welded aluminium foil maintains excellent flatness, electrical conductivity, and mechanical integrity, even for thin, wide, or laminated foil structures.

🧪 Typical Applications:

Aluminium foil laminations

EV battery aluminium current collectors

Energy storage and power battery foil components

Flexible aluminium connectors

Lightweight electrical and electronic parts

Laminated aluminium busbar foil
