2) it is bonded：The coupling internal wall of pipe orifice to be bonded and thin-wall aluminum alloy pipe fitting bonding agent being applied to respectively after polishing
Then the nozzle to be bonded of thin-wall aluminum alloy pipe fitting is inserted into coupling nozzle to be bonded and glues by nozzle outer wall to be bonded
It connects；
3) pressure distortion is handled：The pipe fitting junction after bonding in step 2) is inwardly squeezed by expansion mechanism, is made thin
The deformation of wall Aluminum Alloy Tube is attached to coupling inner wall, improves the tensile strength of thin-wall aluminum alloy pipe fitting and coupling, carries
High sealing effect；
4) curing process：It is small that pipe fitting after deformation process in step 3) is put into 10 DEG C~20 DEG C of environment solidification 72
When, it is then put after standing 48 hours into 20 DEG C~30 DEG C of environment.
Further, the bonding agent is formulated by the raw material of following weight percentage：Epoxy resin 52%, low molecular weight polycaprolactone
Amide 38%, drying silica flour 10%；
