摘要： PURPOSE:To assure the quality of a weld zone at all times through adaptation to change in the contact state between materials to be welded and electrode crushing conditions by controlling the pressurizing force between electrodes and welding current in such a way that the voltage simultaneously with the resistance between the electrodes are made coincident to respective reference curves during conduction of welding current. CONSTITUTION:Welding current is conducted from the secondary side of a transformer 4 between electrodes 2a, and 2b grasping materials 1a, 1b to be welded by pressure, and a circuit 5 sends the voltage between the electrodes momentarily. On the other hand, a circuit 7 sends welding current momentarily, and a circuit 9 detects the resistance between the electrodes. This is compared with the value of a circuit 10, and the pressurizing force of a cylinder 3 is controlled, whereby the resistance between th electrodes is so changed as to coincide with a reference resistance curve. At the same time, the value of the circuit 5 is compared with the value of a circuit 21, and the voltage between the electrodes is changed in conformity with a reference voltage curve with a circuit 15. The voltage of an electric power source 14 is compared with the value of a circuit 23 momentarily, and the value of the circuit 24 is corrected with a circuit 26 and a firing phase angle is controlled with circuit 15, so that reference welding current is maintained constant despite fluctuations of the source voltage.

摘要： PROBLEM TO BE SOLVED: To obtain a large grown nugget while avoiding generation of spatters and sparks in spot welding.SOLUTION: For example, a resistance value of a first electrode tip 12 to a second electrode tip 14, in a state where a laminate 20 is clamped and pressurized, is constantly obtained. An electric current is passed from the first electrode tip 12 to the second electrode tip 14, resulting in formation of a melted part 40 between a first metallic plate 16 and a second metallic plate 18, which slows down a rising rate of the resistance value. On the basis of the fact, it is determined that the melted part 40 is formed, and at the same time, a pressing force of the first electrode tip 12 and the second electrode tip 14 with respect to the laminate 20 is instantly reduced.
