In this embodiment, the cylinder body of the pressure cylinder 4 causes the main electrode mechanism 1 to press one side of the workpiece through the interaction of the mounting plate 5 and the floating plate 6, and the output end of the pressure cylinder 4 causes the secondary electrode mechanism 2 to press the other side of the workpiece through the action of the pressure spring mechanism 3, so as to achieve the purpose of pressing and pressurizing the workpiece. Because there is the clearance between connecting plate 9 and the joint 10 that floats, make the overall structure of tool be in the floating state, simultaneously, pressure cylinder 4 is connected with vice electrode mechanism 2 through pressurization spring mechanism 3, makes vice electrode mechanism 2 be in the floating state, through adopting the structure to fixed the work piece, both sides electrode are the floating state, and along with the thickness of circular telegram welding work piece diminishes gradually, main electrode mechanism 1 floats along with the work piece deformation with vice electrode mechanism 2 through overall structure's float volume, guarantees that the solder joint is located work piece central point.
