Japan's DAIA rebar cold cutting technology: complete guide, specifications and benefits for welding forgings\r\n\r\n A revolution in rebar preparation for forging welding\r\n\r\nA unique product engineered in Japan, the DAIA (DAIA) SDC Series Rebar Cold Cutting Saw defines a new standard in rebar preparation for the sensitive butt forging welding process. Using advanced cold cutting technology, this specialized device creates a completely smooth, perpendicular surface without metallurgical defects, which dramatically increases the final quality of the connection. This device is not an ordinary tool, but a precision engineering solution for professionals who seek the highest standards in civil and industrial projects.\r\n\r\n Full description of cold cutting technology\r\n\r\n"Cold cutting" technology, which is at the heart of Daya's SDC series saws, is an advanced mechanical cutting process that is fundamentally different from traditional methods such as abrasive cutting or hydraulic shearing. Understanding these differences reveals the reason for the absolute superiority of this device:\r\n\r\nCutting process without heat and sparks: Unlike forging mills, which wear at high speed, produce intense heat (above 1000 degrees Celsius) and cause sparks and a heat-affected zone (HAZ) in the rebar cross-section, cold cutting technology uses a very hard alloy steel blade and a powerful motor with high torque and low rotation speed. This mechanism precisely and mechanically "cuts" the steel instead of burning it. The result of this process is no change in the molecular structure and mechanical properties of the steel at the cutting site, which is vital for a strong and reliable forging weld.\r\n\r\n* Creating a completely smooth and vertical cross-section surface (Mirror-Finish Surface): The precise fixer mechanism of the device keeps the rebar completely fixed and the blade creates a cut at an exact 90 degree angle with a controlled movement. The final surface obtained is completely smooth, polished and without any burrs. This feature completely eliminates the need for any secondary operations such as grinding; A process that in other methods is not only time-consuming and expensive, but can never produce the same precision as cold cutting.\r\n\r\nInternal mechanism and precision gears: One of the secrets of the durability and cutting quality of the Daya saw is the use of strong steel gears and machined with high precision in its power transmission system. This advanced design minimizes machine vibration during cutting. Vibration reduction has two key benefits: firstly, preventing premature blade failure or lipping and secondly, significantly increasing the useful life of the blade, which ultimately leads to reduced operating costs. This is the point where Chinese and domestic copies fail.\r\n\r\n Technical and operational advantages of Daya cold cutting technology\r\n\r\nUsing DAIA cold cutting saws in projects brings unique competitive advantages that directly affect quality, speed and cost.

Where to get complete equipment and spare parts for rebar forging welding?\r\n\r\n Specialized reference for providing forging equipment in Iran\r\n\r\nAccess to a complete, high-quality, and coordinated set of equipment, consumables, and spare parts is vital for the perfect and standard execution of the butt-bar forging welding process. As the founder of this technology in Iran and a pioneer in the localization of its equipment, Azmoun Foulad Structural Engineering Company is a specialized and comprehensive reference that provides all the needs of contractors and executors of large construction projects with the highest level of quality and technical support.\r\n\r\n Technical and functional description of the components of a complete forging system\r\n\r\nA complete welding forging system is a collection of precise mechanical, hydraulic and thermal components whose coordinated operation results in a strong and integrated molecular bond. Understanding the role of each part reveals the importance of using standard equipment:\r\n\r\n 1. Rebar cold cutting saw (cutter): This device is the starting point of a perfect weld. Its task is to create a cut with an exact angle of 90 degrees and a completely smooth surface (Mirror-Finish) without creating a heat-affected zone (HAZ). Any deviation from this state will cause a gap between the two ends of the rebar and as a result, an incomplete and unreliable weld.\r\n 2. Rebar holding clamp (clamp): This piece, which consists of two fixed and movable jaws, is responsible for accurate alignment and powerful restraint of the two ends of the rebar. The precise design of the jaws and its smooth movement mechanism ensure that the two bars remain perfectly aligned during the heating and pressing process.\r\n 3. Hydraulic system (pump and cylinder): The beating heart of the process is the hydraulic system. The Electric Hydraulic Pump Unit delivers oil to the Hydraulic Cylinder at very high pressure (the Japanese standard recommends at least 70 MPa or 700 bar). This controlled pressure provides the necessary force to fuse (forge) the two rebar ends that have reached the paste temperature. Having an accurate pressure gauge to control this step is critical.\r\n 4. Thermal system (torch, nozzle and fire ring): Gas torch produces a flame with a temperature of about 1300 degrees Celsius by accurately mixing oxygen and acetylene gases. This flame spreads evenly and 360 degrees around the connection point through nozzle and fire ring so that homogeneous heat reaches both ends of the rebar at the same time.\r\n 5. Gas control system (capsule and manometer): Accurate control of gas pressure is necessary to achieve standard flame. The pressure of oxygen gas is usually between 5 and 7 bar and the pressure of acetylene gas is about 0.5 bar by accurate manometers. Manometer strap (Crepi) is also used for more stabilization and safety of these sensitive parts.\r\n\r\n Key features of our products and services\r\n\r\n Complete and integrated set of forging equipment: We supply all the required components from the largest devices to the smallest consumable parts in one place.
