ME Welding Joint Method for Enclosed Welded Joints of Irregularly Shaped Rebars

ME Welding Joint Method for Enclosed Welded Joints of Irregularly Shaped Rebars

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.

[Technical Introduction] Reinforced Steel Welding Joint N-NT Method

[Technical Introduction] Reinforced Steel Welding Joint N-NT Method

It is possible to join fixed rebar! Suitable for precast methods and rebar pre-assembly methods!

The "N-NT Method" is a rebar welding joint method that joins rebar using a semi-automatic carbon dioxide arc welding technique. Steel materials are processed into a semicircular shape and attached to the two rebars to be joined, with a joint sleeve equipped with a welding root spacing guide in the central part to maintain the root spacing. Additionally, the backing plate functions to hold the rebar and fill it with welding metal. 【Features】 ■ Excellent workability ■ Portable construction equipment makes it easy to work in narrow spaces ■ Allows for joining fixed rebars without pulling them together ■ Suitable for precast methods and rebar pre-assembly methods ■ Use of improved joint sleeves (dragonfly-type sleeves) expands the inspection range *For more details, please refer to the external link page or feel free to contact us.
