Latest Patents

Kenji Sahashi holds a patent for a resistance spot welding method of aluminum material, along with a control device and a welding machine. This patent describes a process where multiple aluminum materials are overlapped and sandwiched between electrodes for spot welding. After the main energization forms a nugget between the aluminum materials, a pulsation energization is performed. This involves repeating the energization and stopping of the energization multiple times, with a current value during pulsation that exceeds that of the main energization. The process includes at least three repetitions of energization and stop, with an increasing energization stop period from the first half to the second half of the pulsation energization.
