Cast iron components are widely used in industrial fields such as engines and machine tools, but their high brittleness has long made welding repair a major challenge-conventional electrodes often lead to cracks and poor machinability. To address this industry pain point, OCEAN WELDING (Dayang Welding) has launched the AWS ENi-C1 cast iron electrode, providing a reliable solution for high-precision cast iron repair.
This electrode stands out with its innovative "pure nickel core wire + high-reducibility graphite coating" design. Unlike traditional products that require 300-500℃ preheating, it enables room-temperature welding, saving equipment and time costs while avoiding workpiece deformation from improper preheating. Its pure nickel core reduces welding stress, and the graphite coating inhibits oxidation, ensuring crack-free welds even on thin-walled parts (thickness < 8mm) or stress-concentrated areas like gearbox corners. After cooling, the weld metal matches gray cast iron's hardness (HB180-220), supporting turning, milling, and grinding-critical for restoring precision to engine bearing seats and machine tool guideways.
Compliant with GB EZNi-1, AWS ENi-C1, and ASME/SFA5.15 standards, the electrode offers multiple specifications (2.0mm-5.0mm diameter) to meet diverse needs. Each batch comes with a moisture-proof 20kg package, independent batch numbers, and material test reports. For bulk orders (≥10 boxes), customers enjoy a 15% discount and free technical guidance.
"Our goal is to let more enterprises solve cast iron repair troubles efficiently," said a representative from OCEAN WELDING. For samples or quotes, contact +86 159 8840 7388 (9:00-18:00 Beijing Time) or online customer service. Remember to check the "OCEAN WELDING" logo and batch number to avoid "three-no" products that risk repair failure.
