Firstly, the second pushing support 44 is located at one end of the second welding frame 42 (i.e. away from the first welding frame 35), then the stud 52 is placed in the large hole of the second pushing support 44 (for example, the stud 52 is placed in the first large hole 44-1 of the second pushing support 44 through a manipulator or a previous process, the manipulator can accurately and effectively grab the workpiece, and stabilize the workpiece at a designated position in the whole welding process, so as to help the workpiece and the stud to realize welding, so that the welding precision is improved, the upper part before the workpiece is welded and the lower part after the workpiece is welded are both operated by the manipulator, so that the non-welding time in the welding process is saved), the fourth laser sensor 39 and the third laser sensor 38 detect the stud 52 and feed back the detected situation to the control mechanism, the control mechanism controls the second rodless cylinder 43 to drive the second pushing support 44 to move towards the first welding frame 35, so that the stud 52 is transported to the other end of the second welding frame 42 (i.e., close to the first welding frame 35, also referred to as the blanking end of the second welding frame 42), the stud 52 in the first large hole 44-1 of the second push bracket 44 passes through the second large hole 42-1 of the blanking end of the second welding frame 42 and then falls into the third large hole 40-1 of the first push bracket 40;

secondly, the fifth laser sensor 41 detects the stud 52 in the third large hole 40-1 and feeds the detected situation back to the control mechanism, the control mechanism controls the first rodless cylinder 37 to drive the first pushing support 40 to move towards the welding mechanism, and the first pushing support 40 moves the stud 52 into the fourth large hole 36-1; synchronously, the control mechanism controls the thin cylinder 46 to drive the flat plate 29 to move, the corresponding group of positioning pins 34, the fixed seat, the fixing clamp 27 and the first cylinder 28 are moved to the position below the fourth large hole 36-1, the stud 52 falls onto the corresponding positioning pin 34 from the fourth large hole 36-1, and the positioning pin 34 is embedded into the central hole in the stud 52 to fix the stud 52;

again, the control mechanism moves the workpiece 51 (i.e., the workpiece 51 to be welded to the stud 52, such as a butterfly-type workpiece 51, made of iron) below the cylindrical pressing piece 09 by a robot (not shown in the drawings), and the cylindrical pressing piece 09 and the stud 52 (made of iron) are aligned in the vertical direction where welding is required on the workpiece 51; then, the first cylinder 28 drives the positioning pin 34 to move upwards until the stud 52 on the positioning pin 34 contacts with the bottom of the workpiece 51 (at this time, the first laser sensor 17-1 and the second laser sensor 17-2 sense the feedback of the stud 52 to the control mechanism, and the control mechanism controls the first cylinder 28 to stop moving upwards), at this time, the first connecting block 12, the second connecting block 13, the third connecting block 20, the first long plate 19, the L-shaped plate 05, the waist-shaped block 07, the first fixing seat 08, the cylindrical pressing block 09, the connecting plate 21, the first U-shaped block 22, the second long plate 23, the second U-shaped block 25, the second fixing seat 26, and the cylindrical support block 45 (short for energization parts) are all energized to form an electrical loop, and synchronously, liquid circulation formed by the water-air interface 50, the water pipe, and the air pipe joint is used for continuously cooling and radiating the energized parts.

Finally, high temperature is generated between the stud 52 and the workpiece 51 in the power-on process, the stud 52 and the workpiece 51 are welded under the action of the high temperature at the position where the stud 52 is in contact with the workpiece 51, after the welding is finished, the control mechanism controls the first cylinder 28 to drive the positioning pin 34 to move downwards, the electric loop is disconnected, the control mechanism removes the workpiece 51 with the stud 52 welded through the manipulator (the workpiece 51 is supported and fixed by the manipulator in the whole welding process), and the welding process of the stud 52 and the workpiece 51 is completed.
