Laser welding head 12 work progress, workpiece 24 and shield 51 formation closed space in temperature constantly increase so that work
The temperature of gas constantly increases in the closed space that part 24 is formed with shield 51, and shield 51 is closed with what workpiece 24 was formed at this time
The pressure closed in space constantly increases, and the bubble in laser welding below solder is because of the closure that shield 51 and workpiece 24 are formed
The reason of pressure in space constantly increases begins to move up, the pressure in the closed space that shield 51 and workpiece 24 are formed
When power reaches peak value, the air pressure valve on shield 51 is opened, and gas moment enters No.1 transverse slat 53, L shape cabinet 52 and shield
In 51 closed spaces formed, the gas in closed space formed with shield 51 with workpiece 24 is constantly discharged, in solder
Bubble continue to move up, final bubble ruptures after being moved to the surface of solder；And moment enters No.1 transverse slat 53, L shape case
Gas impact No.1 transverse slat 53 in the closed space that body 52 and shield 51 are formed moves up, and No.1 transverse slat 53 moves up
While compression No.1 transverse slat 53 and No. two transverse slats 54 between gas make gas from No. two transverse slats 54 gas outlet be discharged, row
No. three transverse slats 55 of gas push out move up, and No. three transverse slats 55 and L shape case are pushed while No. three transverse slats 55 move up
The liquid ethanol in closed space that body 52 is formed flows into coiled pipe 14, and the liquid ethanol in coiled pipe 14 is in coiled pipe 14
The ethyl alcohol of the heat generated when absorbing 12 welding workpiece 24 of laser welding head when flowing, liquid becomes gas from liquid because absorbing heat
It is gaseous in the closed space that state flows into No. three transverse slats 55 on 4 right side of guard box out of coiled pipe 14 and L shape cabinet 52 is formed
The cooling medium in closed space that No. three transverse slats 55 on 4 right side of ethyl alcohol and guard box are formed with L shape cabinet 52 contact after again
Become liquid, the liquid ethanol in closed space formed with No. three transverse slat 55 and L shape cabinets 52 on 4 right side of guard box is more next
More, No. three transverse slats 55 move down, and No. three transverse slats 55, which move down, pushes 55, No. two transverse slats 54 of No. three transverse slats and L shape cabinet
Gas in 52 is discharged from the gas outlet on No. two transverse slats 54, and the gas of discharge drives No.1 transverse slat 53 to move down, and No.1 is horizontal
Plate 53 pushes away column 56 and No. two push rods 71 is pushed to tilt down No. two push rods 71 when moving down, two when No. two push rods 71 tilt down
Piston head 73 on number 61 other end of lever is extracted, in the closed space that No.1 transverse slat 53, L shape cabinet 52 and shield 51 are formed
Gas discharge；Similarly, with the liquid in No. three transverse slats 55 on 4 right side of guard box and the closed space of the formation of L shape cabinet 52
Ethyl alcohol is more and more, in the closed space that No. three transverse slats 55 and L shape cabinet 52 in alcohol reflux to the left side of liquid are formed, finally
So that the gas discharge in the closed space that No.1 transverse slat 53, shield 51 and the guard box 4 in 4 left side of guard box are formed, finally,
Laser-beam welding machine 1 is closed, the work being welded is removed, the welding of entire workpiece 24 terminates.
