Meaning and Definition
A solid-state welding process where two metal surfaces are joined by applying high pressure, usually at elevated temperature, without melting the base materials.
A category of welding techniques where coalescence is produced by the application of pressure sufficient to cause deformation of the parts, enabling atomic bonding through diffusion or recrystallization.

FAQ
Frequently Asked Questions
Not exactly. Spot welding is a specific type of resistance welding where pressure is applied, but it is often classified separately. All spot welding involves pressure, but not all pressure welding is spot welding (e.g., cold pressure welding, forge welding).
The term is almost exclusively used for metals. Joining plastics with pressure and heat is typically called 'heat sealing' or 'welding', but rarely 'pressure welding' in technical parlance.
Advantages include no filler metal required, minimal heat-affected zone, ability to join dissimilar metals, and often no need for a protective atmosphere (in cold pressure welding).
Aerospace (for critical components), automotive (for wire splicing, some structural parts), electrical (for contacts and terminals), and metal fabrication for specialised applications.
A solid-state welding process where two metal surfaces are joined by applying high pressure, usually at elevated temperature, without melting the base materials.
Pressure welding is usually technical / industrial in register.
Pressure welding: in British English it is pronounced /ˈprɛʃə ˈwɛldɪŋ/, and in American English it is pronounced /ˈprɛʃər ˈwɛldɪŋ/. Tap the audio buttons above to hear it.

Memory Aids
Mnemonic
Think of a powerful press squeezing two metal pieces until they become one — welding through PRESSURE, not heat alone.
Conceptual Metaphor
JOINING AS FORGING (coalescence through forceful unification).
