The working process of the invention is as follows:

s1, positioning of the left belt material: a worker inserts the positioning posts C19 on the lower surface of the positioning strip 4 into the positioning holes I18 on the fixing base 6 respectively, and supports the positioning strip 4 on the top surface of the fixing base 6, at this time, the left end surface of the positioning strip 4 is just suspended right above the groove 16 as shown in fig. 9; the worker pulls up the guide plate 14 around the hinge base 13, keeps the pressing plate 15 still after pulling up, then the worker puts the two drawing holes 2 on one frame 1 of the left belting 26 on the two positioning posts a12 of the left positioning device 7 respectively, and supports the left belting 26 on the top surface of the workbench 9 of the left positioning device 7, then the worker moves the left belting 26 to the right to make the head end part of the left belting completely fit on the left end surface of the positioning strip 4, and after fitting, the worker puts down the guide plate 14, and after the pressing plate 15 is put down and pressed on the top surface of the left belting 26, the positioning of the left belting is finally realized as shown in fig. 10;

s2, positioning of the right belt material: the worker pulls out the positioning strip 4 from the positioning hole I18 and removes it; the worker pulls up the guide plate 14 of the right positioning device 8 around the hinge base 13, and then the worker fits the two drawing holes 2 of one of the rims 1 of the right tape 27 over the two positioning posts a12 of the right positioning device 8, respectively, and supports the right tape 27 on the top surface of the table 9 of the right positioning device 8; then the worker moves the right tape 27 to the left so that the head end of the right tape is completely attached to the head end of the left tape 26, and finally the pressing plate 15 is laid down, and the laid pressing plate 15 is pressed against the top surface of the right tape 27 as shown in fig. 11, so that the right tape is positioned, and the contact position of the head end of the left tape 26 and the head end of the right tape 27 is just above the groove 16;

s3, compressing the head ends of the left and right belt materials: a worker respectively sleeves two positioning holes II21 on the lower surface of the pressing plate 5 on two positioning posts B17, and supports the pressing plate 5 on the top surface of the fixed seat 6, at this time, the head ends of the left belt material 26 and the right belt material 27 are pressed by the pressing plate 5, and the contact position of the two belt materials is just under the gap 20 as shown in FIG. 12;

and S4, turning on the welding machine, irradiating the contact part of the two strips by a laser beam emitted by a welding head of the welding machine through the gap 20, welding the irradiated parts together, and then moving the welding head along the length direction of the contact part, thereby finally welding the two strips into a whole.

Because in welding process, the head end portion of left area material 26 and right area material 27 all is compressed tightly between fixing base 6 and clamp plate 5, has consequently avoided the head end portion perk of two area materials to very big improvement welding quality. In addition, the left belt material 26 and the right belt material 27 are respectively positioned and pressed through the steps S1 and S2, so that the welding positions of the two belt materials are completely attached, and the welding quality is further improved. In addition, the contact position of two beltings is in unsettled state, and the welding part after the welding can not welded on the workstation to the finished product belting after having made things convenient for the workman to take off the welding.

When the width of area material changes, can unscrew locking screw 25, then slide pressure strip 15 along deflector 14, after pressure strip on the workstation can be pressed to pressure strip 15, tighten locking screw 25 again in order to fix pressure strip 15 to can compress tightly the area material of different widths, be applicable to the welding of different width area materials.
