Product range
As the star product of Ocean Welding's nickel-based alloy welding material series, ENiCrMo-4 has unique performance and a wide range of applications.
The nickel-based alloy welding material series is designed to cope with various harsh welding conditions, and ENiCrMo-4 is particularly outstanding. It is mainly used for welding nickel-chromium-molybdenum alloys, such as Inconel 625, Incoloy 825, etc. This welding material has excellent thermal crack resistance and excellent corrosion resistance, and can ensure the stability and reliability of the welded joints in high temperature, high pressure environment, or in highly corrosive media.
In the field of marine engineering, it is used to weld key structural parts of offshore platforms to resist seawater erosion and harsh climatic conditions; in the petrochemical industry, it can be used to weld various types of reactors, pipelines and other equipment, and withstand high temperature, high pressure and chemical medium corrosion; in the field of aerospace, for the welding of some nickel-based alloy parts, ENiCrMo-4 can also play its excellent performance, ensure welding quality, and meet high-precision welding requirements.
Quality Certification
Ocean Welding has always regarded product quality as the lifeline of the enterprise, and ENiCrMo-4 has undergone strict quality control and multiple authoritative certifications.
The product has passed the ISO9001 international quality management system certification, which means that we follow the international standardized quality management requirements in the entire process of product design, production, sales and after-sales service to ensure that every link meets high quality standards.
At the same time, ENiCrMo-4 has been recognized by eight classification societies including China (CCS), Britain (LR), the United States (ABS), France (BV), Norway (DNV), Germany (GL), South Korea (KR), and Japan (NK). These certifications fully demonstrate the reliability and applicability of the product in the field of shipbuilding and marine engineering, and can meet the strict quality requirements of different countries and regions for shipbuilding and maintenance. In addition, our products have also passed the welding management system certification, which further guarantees the quality stability of the product and the standardization of welding operations.
Comparative Analysis
Compared with similar nickel-based alloy welding materials, Ocean Welding's ENiCrMo-4 has significant advantages.
In terms of thermal crack resistance, by optimizing the alloy composition and manufacturing process, ENiCrMo-4 has lower thermal crack sensitivity. During the welding process, it can effectively reduce the occurrence of thermal cracks, greatly improve the quality and reliability of welded joints, reduce the risk of welding defects caused by cracks, reduce the number of rework, and improve production efficiency.
In terms of corrosion resistance, ENiCrMo-4 performs better. Its unique alloy ratio enables it to maintain good corrosion resistance in a variety of corrosive media. For example, in a solution containing chloride ions, similar products may corrode, while ENiCrMo-4 can resist corrosion for a long time, extend the service life of the welded structure, and save users equipment maintenance and replacement costs.
In terms of welding process performance, ENiCrMo-4 has good arc stability and slag removal. During the welding process, the arc burns stably, spatter is small, and the operation feels comfortable, which allows welders to complete welding work more easily. At the same time, slag removal is easy, the weld is beautiful, and there is no need for excessive subsequent grinding, which further improves production efficiency and economic benefits.
FAQ
Q: How to choose the appropriate current when welding ENiCrMo-4?
A: It is recommended to choose the appropriate welding current according to the thickness of the welding base material and the welding position. Generally speaking, for thinner base materials, a smaller current is used; for thicker base materials, the current is appropriately increased. For example, when welding 3mm thick nickel-based alloy plates, the current can be selected to be 100-120A; when welding 6mm thick plates, the current can be adjusted to 150-180A.
Q: When welding ENiCrMo-4, what is the appropriate welding speed?
A: Maintain an appropriate welding speed. Too fast may cause insufficient weld penetration, and too slow may cause the weld to overheat and deform. Usually, it is more appropriate to control the welding speed at 15-30cm/min, which can be adjusted according to the actual welding situation.
Q: When welding ENiCrMo-4, what are the requirements for the angle between the electrode and the weldment?
A: The angle between the electrode and the weldment is generally maintained at 70°-80°, which can ensure arc stability and obtain good weld formation. When welding in different positions such as flat welding, vertical welding, and overhead welding, the welding angle needs to be fine-tuned according to the actual situation.
Q: In what environment should ENiCrMo-4 be stored?
A: ENiCrMo-4 should be stored in a dry and well-ventilated environment, and the indoor relative humidity should be controlled below 60%. Avoid storing in humid places with corrosive gases to prevent the welding materials from getting damp and rusting, which will affect the welding performance.
Q: How to store unused ENiCrMo-4?
A: Unused welding materials should be sealed and packaged in time. Plastic bags or sealed containers can be used to store them to prevent moisture and impurities in the air from entering. The next time you use it, if you find slight rust on the surface of the welding material, you can use sandpaper to gently grind it and remove it before welding.
Q: What is the shelf life of ENiCrMo-4? Can it still be used after the expiration date?
A: Under the condition of meeting the storage conditions, the shelf life of ENiCrMo-4 is generally 2-3 years. Welding materials that have exceeded the shelf life must be re-inspected to confirm that their welding performance meets the requirements before they can be used.
