adhesive bonding can be employed to reinforce mechanical
joints, and in its own right for joining thin stainless steel
sheets.
the advantages of adhesive bonding are:
• there is no modification of the surface appearance,
geometry or microstructure of the assembled areas.
• dissimilar materials can be joined easily and
aesthetically.
• correctly designed, joints can have excellent fatigue
strength.
• the method can provide thermal, electrical or acoustic
insulation.
• parts of varying thickness can be joined.
points to take into consideration, however, include the
fact that such joints will tend to have a temperature limit
of 200°c and will have a certain sensitivity to moisture.
adhesive joints will not be as strong as joints produced by
welding or brazing. for this reason they are mostly used
to produce lap joints, with the load spread over a sufficient
area to limit local stresses.

it is also possible that a smooth-surfaced stainless steel
(especially bright annealed) will not have good adhesive
properties.
after roughening, surfaces should be very clean, dry and
well prepared. the essential condition for good bonding is
satisfactory wetting of the substrate by the adhesive.
as an example of adhesive bonding, bus and coach
manufacturers now often construct a body frame of stainless
steel shaped sections, often in ferritic grade 1.4003/410.
the skin (sheet and/or glass) is adhesively bonded to this
body frame. this approach increases the vehicle’s life and
reduces its weight.
