As is apparent from the above description, the position of the welding gun 22 in the vertical direction can be adjusted by the first linear reciprocating device 23 to ensure the distance between the welding gun 22 and the frame 4 to be welded; the welding gun 22 may be controlled horizontally toward or away from the frame 4 to be welded using the second linear reciprocating device 24 to ensure that the welding gun 22 is aligned with the weld of the frame 4 to be welded.

Further, the frame welding device further comprises a swing motor, the swing motor is arranged at the movable end of the second linear reciprocating device 24, and the output end of the swing motor is connected with the welding gun 22.

As can be seen from the above description, the swing motor is used to drive the welding gun 22 to swing, so that the welding gun 22 does not stay in a position for a long time in the forward welding process to control the temperature of the molten pool and avoid burning through the frame 4 to be welded.

Further, the swing speed of the welding gun 22 is 0mm/min to 110mm/min, and the swing angle of the welding gun 22 is minus 20 ° to plus 20 °.
