With a total of 2 patents to his name, Tejima's innovations have advanced the efficiency and effectiveness of welding processes.

Latest Patents

Tejima's latest patents include a TIG welding apparatus and method. This apparatus features a twin electrode type welding torch with a first and second welding electrode arranged approximately parallel to each other, separated by an insulation plate of a predetermined thickness. The main unit supplies a first welding current to the first electrode and a second welding current to the second electrode, both varied at a first period and in opposite phases. This design allows for an increase in arc current without raising the welding current. Another significant patent is the all-position TIG welding process, which utilizes controlled welding current pulses. This method feeds DC current pulses at frequencies ranging from tens to hundreds of Hz to the electrode and filler wire, creating a stable and positive molten metal pool due to the high arc pressure achieved.
