2. Bonding and Riveting or ‘Cold Joining’
The modern car is now being built using a mix of materials that best suit the job
The cars must be strong, in the case of an accident, and lightweight for economy
The materials used will have to be re-cycled at some time in the future
The vehicle may need repairing during its lifetime
The Materials being used
• Various strengths of steel
• Aluminium
• Plastics
• Composites
• Carbon Fibre
Welding is not possible so different methods
for joining these materials is necessary

3. Bonding and Riveting or ‘Cold Joining’
Where the materials can’t be welded, they will be glued
together and then held in place using rivets
• Epoxy Resin 2 pack glue must be used
• It is very strong when used correctly
• Withstands temperatures from the Antarctic to the Sahara
• It can cope with oil and grease
• It gives a very robust repair
• This is proven technology, many aircraft are glued together
Glue. What type?
Where welding is impossible, it is probable that rivets
and glue will be used instead

4. Bonding and Riveting or ‘Cold Joining’
• Self piercing rivets (SPR’s)
• Flow form rivets (FFR’s)
• Blind rivets, Pop rivets
• Rivet nuts
• Blind rivet studs
• Rivet nut studs
• Clinching
• Punching
• Screws
• There are many more rivets to come…..
Some of the different types of rivets being used in car repair today
What type of Rivets? Blind Rivets
Keeping up with all the changes is a nightmare for the bodyshop owners!

5. Bonding and Riveting or ‘Cold Joining’
Equipment. What type?
Blind Rivets, Pop rivets
• Each rivet has a specifically designed ‘breaking point’
• If the wrong tool is used, the rivet may not be securely fitted
• Not every rivet gun can pull every rivet
• Not every tool is powerful enough for the job
• The rivet may be too big to fit the mouthpiece
• Buying different tools for different rivets
is both expensive and unnecessary
Take a look at the XPress 800 BR50

6. Bonding and Riveting or ‘Cold Joining’
Blind Rivet Adaptor. BR50
• One tool for all jobs (no more buying piecemeal)
• Designed to fit any blind rivet
• For steel
• For aluminium
• Maximum pulling strength 5 tons
• Very economical
Blind Rivet Adaptor. BR50
• Used to fit any blind rivet up to two tons force
• For steel, for aluminium, for plastics
• To get into places where no other tool can reach

7. Bonding and Riveting or ‘Cold Joining’
Self Piercing Rivets SPR’s
Flow Form Rivets FFR’s
What type of Rivets? SPR’s and FFR’s
Self Piercing Rivets SPR’s
• Not every rivet tool can fit every SPR
• Most rivet tools have a maximum force of only 5 tons
• In many cases the rivet needs a greater force
• The wrong force means a faulty connection
• There is no way to upgrade the rivet tool
Flow Form Rivets FFR’s
• For fitting rivets into an existing hole
• Used for steel, aluminium, plastics, composites
• Pushes from both ends, no contact with the material
• Needs up to 9 tons of clamping force
• This may become the standard in repair

8. Bonding and Riveting or ‘Cold Joining’
Fitting SPR’s AND FFR’s
• Change the dies to suit the type of rivet (SPR or FFR)
• Important to set the speed and pressure
• For steel check the rivet is suitable
• For aluminium make sure the length is correct
• Always use glue in the repair
Self Piercing Rivets SPR’s
Flow Form Rivets FFR’s
Modular rivet system XPress 800
• With all these requirements to think about the modular
concept would probably suit. Just one tool to do all jobs
One base tool with different
adaptors. Simple but effective

9. Bonding and Riveting or ‘Cold Joining’
Modular rivet system.
One basic Power Pack with 8 tons of force
• Fits Blind rivets
• Fits SPR’s
• Fits FFR’s
• Fits Rivet nuts (4mm to 12mm)
• Fits Rivet studs
• Replacement rivets available
• All stored into a professional work trolley

Bodyshop Solutions Ltd has great pleasure in announcing
that their Modern Bonding and Riveting Programme
has been approved by the IMI under their
Quality Assured Awards (QAA) Scheme.
Training for Bonding and Riveting
Bonding and Riveting of modern motor cars is a repair process that is a mystery to many
bodyshops and in particular the independent repairer who is losing work because of the lack
of knowledge and training on this subject.
The purpose of this training and certification programme is to make available the knowledge
and skills to all bodyshop personnel and it covers in-depth information on types of glue, types
of rivets and the reasons why this new exciting repair process is so important.
