Murata Welding Laboratories Co., Ltd.
We specialize in thin-sheet butting welders.
Our company manufactures and sells automatic welders for thin sheet metal materials, including hoop materials, and tungsten grinders. Thin-sheet butt welding produces various items that we see everywhere in daily life, but it requires a high level of skill. We provide devices for safe butt welding with high yields without requiring such skill. We elaborate high-level techniques in our products at the design stage so everyone can easily perform high-quality welding. Our unique welding technology is highly evaluated, and we were selected for the Global Niche Top Companies Selection 100 by the Ministry of Economy, Trade and Industry. We have a track record of doing business with Japanese companies like Rinnai and Komatsu, as well as Indonesian and Korean companies.
[Company strength] We are professionals specialized in highly difficult thin-sheet butt welding. Butt welding of thin sheet metal materials has been considered difficult because it easily causes burning through, or results in distortion after welding. Our devices are designed to help anyone to easily perform high-quality welding. High-level techniques are elaborated in devices at the design stage, so even part-time workers without great skills can manufacture products by high-grade welding after a lecture of about 30 minutes. Our products are interactive devices. Users can operate them by following messages. Our products can be easily used even outside Japan if they give messages in the corresponding languages. They make a great contribution to annual cost reduction because welding flaws and losses decrease drastically. [Business description] We are an R&D company that manufactures and sells automatic welders for thin sheet metal materials, including hoop materials, and tungsten grinders. Butt welding of thin sheet metal is applied in manufacturing sealed containers like tanks, washing machine drums, water supply vessels, and various other metal articles. We also manufacture and sell hoop welders dedicated to thin sheet metal welding for commonly used ribbon-shaped hoop materials or press machines. Thin-sheet butt welding is used to manufacture various items that we see everywhere in daily life, but this processing requires a high level of skill. We provide devices for safe butt welding with high yields without requiring such skill. [Industry] Manufacturing (main product: automatic welders for thin sheet metal) [Strength of products/technologies] We manufacture a tank by joining a thin sheet cylindrically and preparing the top or bottom. Airtightness in joining is important to prevent water or air leakage. The metal is thinner, so the processing is more difficult. Our devices can perform even such difficult welding with almost no flaws while maintaining high production efficiency. Our welding technology is highly unique, and we were selected for the Global Niche Top Companies Selection 100 by the Ministry of Economy, Trade and Industry. Three companies participated when Kamioka Nucleon Decay Experiment Facilities procured bellows tubes by bidding, but only one company which used our device successfully met the required specifications for high airtightness. Our devices ensure deep burning through for hoop materials, even when butt-welding ultra-thin sheet metal 0.1 mm thick. [Representative's message] The significance of our company is to develop the welding field and new application fields through the endless pursuit of other joining methods. Thin-sheet butt welding ranks high in difficulty among various welding methods. We develop and manufacture products based on our unique technology so everyone can easily perform welding with high quality. Overseas exports are also increasing. We hope that our devices will be used in Japan and everywhere in the world. We will be happy if our products make a contribution to the development of manufacturing industries. We prioritize technical development by inventions and devices. We have been able to acquire many patents and invention-related awards though knowledge collaboration with Osaka University. We will continue to pursue high-quality joining devices that are truly easy to use everywhere in the world beyond language barriers. [Company structure for market development/overseas expansion] Thin sheet metal welders should be developed by considering work materials and shapes. We develop products in cooperation with customers. Our company is a professional in thin sheet metal welding using TIG. We have a backup system, such as verification by the Joining and Welding Research Institute, Osaka University. We have a track record of overseas exports and provide display screens in languages used in Asian countries. [Market share/Ranking] There are no similar devices because our products are patented. [Awards and media coverage] [Awards] New Value Creation Exhibition, New Value Creation Award (2015); Commendation for Kinki Regional Invention 2015, Governor of Osaka Prefecture Award; the 27th SME New Excellent Technologies and Products Prize; the 39th Invention Award, "Distinguished Invention Award." [Media] Nikkan Kogyo Shimbun, intensively serialized in "SME Stories" (February 14 to 17, 2012). [Joint research and development] We jointly developed a constriction nozzle for our devices with the Joining and Welding Research Institute of Osaka University. We acquired Japanese Patent Registration No. 5602974 for the constriction nozzle and a TIG welding torch using it. [Main Clients / Business History (domestic)] Many transactions, including horizontal automatic welders with Sakura Kogyo, Samsung, Rinnai, Komatsu, Uno Kogyo, Kagawa Industry, Osaka University, and Hitachi Industrial Equipment Systems, and system hoop welders with Sumiko Tec, Denso, and Yutaka Giken [Main Clients / Business History (overseas)] Many transactions in Indonesia, Korea, and so on.
