Secondly, two blocks of aluminium alloys are fixed on the workbench that two pieces can perform relative motion, start vibrator（It can be used often
Rule design is realized）It drives workbench to move back and forth along the direction of weld seam, makes the coupling surface of two pieces of aluminum alloy plate materials because of friction
Heat and temperature increase；Two workbench can move toward one another, can also one it is dynamic, one is motionless；
Third, with the temperature of far infrared temperature measurement sensor measurement coupling surface, when the temperature of aluminium alloy coupling surface reaches setting
When value, two workbench is made to stop opposite reciprocating motion；At this point, two workbench should be made to keep for the ease of friction dial work
Certain gap, and two pieces of aluminum alloy plate materials should be at couple state（It can be by adjusting the position of aluminum alloy plate materials on the table
Set realization）, on the one hand can keep the temperature, on the other hand convenient for operation in next step；
4th, make to be located at the friction dial below workbench（Top is conducive to the rough of increasing friction force
Structure）It is contacted simultaneously with two pieces of aluminum alloy plate materials in the gap ascended between two workbench, starting friction dial friction two
The bottom of block aluminum alloy plate materials is brought rapidly up the bottom of two pieces of aluminum alloy plate materials to set temperature value（Using far infrared temperature measurement
Device measurement）, decline friction dial；As shown in Figure 2；
5th, pressing plate is put in two pieces of aluminum alloy sheet material surfaces（Bottom is conducive to the uneven of increasing friction force
Structure）, and start that pressing plate is reciprocating, so that the temperature of two pieces of aluminum alloy plate materials upper surfaces is risen to setting value（It can also adopt
It is measured with far infrared temperature measurement instrument）, remove pressing plate；As shown in Figure 1；
