What is weld cladding and Flange with Inconel cladding

1. What is weld cladding and Flange with Inconel cladding Weld overlap cladding flanges are also known as cladding flanges. This flange is used in the weld technology process to build corrosion-resistant alloy layers that replace the solid metal. For offshore projects or underwater pipelines, corrosion resistance requirements are highly indisputable. Clad is a better way to prevent corrosion of low alloy materials involved in flange forging. Coating Inconel 625 Round Bar pipes are more economical than using double stainless steel or Ni-based alloys. Most of the products are currently manufactured using carbon steel as the substrate and Inconel 625 Plate (nickel alloy 625/715) and SS as the coating material for adhesion. This article describes a low-cost optimization solution for carbon steel flanges. Inconel 625: The Inconel 600 Tube is used as both a high strength base material and excellent water and corrosion resistance, or as welding filler. The strength of nickel alloy 625 is mainly due to the solid solution effect of molybdenum and columbium. Nickel Alloy 625 has excellent weldability. Corresponding filler metal is often used to join dissimilar metals and weld water-based corroded steel. INCONEL 625 brazed alloys can be easily joined using traditional baking processes and procedures. Weld cladding

2. The term weld coating generally means applying a relatively thick layer of weld metal (3 mm or more) to provide a corrosion-resistant surface. Typical base metal components of Inconel 718 Round Bar to be welded include the inner surface of carbon and low alloy steel flanges. The lining is usually austenitic stainless steel or a nickel-based alloy (625 or 715). Weld cladding of Inconel 625 Tube is typically done by the GMAW process, laser process, or underwater arc welding. However, flux arc welding (self-shielding or gas), plasma arc welding, and electroslag welding can also produce welded coatings. The filler metal can be used as a coated electrode, winding electrode wire, and strip electrode. Weld Overlay and Process Used The GMAW process performs liner welding, and after a series of tests, the coated Inconel 625 Pipe is suitable for underwater applications and approved according to requirements. The flange had an easily damaged and corrupt channel, so it had to be solder with a corrosion resistant material (625). Welding was performed by an automated GMAW process in a lined grooved area, machined to the required dimensions, inspected, and tested. Non-destructive test: visual test / dye penetration test / magnetic particle test Visual, LPT, and MPT inspections are performed on the coated Inconel 600 Pipe after final machining. The NDT test requires a qualified NDT operator. The surface of the forging was cleaned with BS7079 before the inspection. NDT testing was performed according to DNV OS- F101App-D.

3. Coating thickness: Coating thickness measurements were performed using the Fischer Deltascope FMP30 / FGB2. The accuracy of the equipment that is important for the Deltascope of Inconel 600 Plate is shown below. The measurement principle of the device by the magnetic method complies with ISO2178. FMP30 Deltascope: DIN EN ISO 2178 / ASTM D7091-Magnetic Guidance Manual Accuracy: Maximum 0.1mm-± 0.0015mm and Accuracy: Maximum 0.1mm-± 0.0003mm Thickness Tolerance Criteria: Defined in the project specifications, the minimum is 3 mm.
