This is a construction method that simplifies work and construction in narrow spaces.
The "ME Welding Joint Method" is an enclosed welding joint that has become prominent in recent years, designed to accommodate the increasing size and strength of concrete structures. This method involves covering the joint between the irregularly shaped rebar with a special copper backing (fixture) that has a carbon dioxide gas nozzle for shielding, and using a semi-automatic carbon dioxide arc welding device to perform the enclosed welding and fabricate the joint. 【Features】 ○ Obtained A-class joint evaluation in the "Welding Joint Performance Evaluation Criteria for Rebar" by the Japan Building Center (BCJ Certification - RC0215-01) → Successfully enhanced the quality performance and construction efficiency of rebar joints ○ Achieved simplification of construction and work in confined spaces ○ Enabled welding with significantly improved shielding properties ○ Can suppress defects caused by wind For more details, please contact us or download the catalog.
