Latest Patents

Among his latest patents is a groundbreaking invention focused on heat manipulation and seam tracking of weaved welds. This invention involves an arc welder that produces a weave pattern between workpieces. Each weld run consists of a center portion that includes a joining region between the workpieces and edge regions that are spaced apart from the joining region. The welder is equipped with a power source that provides a welding waveform to a welding electrode, generating an arc to achieve the desired heat for welding. Additionally, it features a welding torch and an oscillator that oscillates the torch between the welding edge regions. The controller operates in two modes, utilizing different waveforms for welding in the joining and edge regions, enhancing the precision of the welding process.

Another significant patent is for a basic metal cored electrode, which is a consumable welding element for arc welding. This element comprises a steel sheath surrounding a compacted core that contains metal alloying powders and a basic compound, specifically calcium fluoride powder. This innovative electrode is designed to decrease the amount of diffusible hydrogen in the weld metal, making it suitable for both TIG and MIG welding applications.
