Short answer: Adhesive bonding joins metals with a cured polymer film that spreads load and seals against corrosion; success depends on choosing the right adhesive (epoxy, acrylic, polyurethane), preparing the surface properly and designing an overlap joint that keeps the bond in shear.

Why Bond Instead of Weld
Bonding joins dissimilar and thin metals without heat distortion, spreads stress and seals the interface — a useful complement to Metal Riveting Guide e Metal Brazing Vs Soldering, and for heat-sensitive parts after Come saldare l'alluminio. It also helps Dissimilar Metal Welding Guide couples avoid galvanic issues.
Preparazione della superficie
Bonds live or die on cleanliness and roughness: degrease per Metal Degreasing Guide, abrade or pretreat, and consider Anodizing Vs Powder Coating o Passivation Vs Pickling for durable surfaces. Measure film and profile with Metal Coating Thickness Guide e Metal Surface Treatment Guide.
Joint Design & QA
Use wide overlaps in shear, avoid peeling loads, and control bond-line thickness. Inspect via Metal Ndt Guide and confirm fit per Metal Tolerances Fits Guide; protect the joint with How To Prevent Metal Rust and certificate per Mill Test Certificate Guide.

Domande frequenti
Two-part epoxies for structural strength, acrylics (MMA) for fast gap-filling bonds, polyurethanes for flexible/damped joints, and anaerobics/cyano for threads and small parts.
Degrease, abrade or grit-blast for a clean rough surface, and apply primer/pretreatment; cleanliness and profile decide bond strength.
A well-designed structural adhesive spreads load and can match welded joints in shear, but it is weaker in peel and heat, so joint design matters.
Yes — a continuous bond seals the interface from electrolyte, which helps avoid galvanic and crevice attack between dissimilar metals.
