Inconel 690 straight weld wires
Inconel 690 straight weld wires are a kind of nickel-based alloy welding material. They are designed for welding similar nickel-chromium alloys like Inconel 690 and 600 or dissimilar metals. They are made of nickel (at least 58%), chromium (28-31%) and a little iron (7-11%). They also have titanium, aluminum and other elements to make them better. They come in straight sticks. The diameter is usually between 1.2mm and 4.0mm. They are good for TIG and MIG welding. They have a good shape and are stable when used.
Inconel 690 straight weld wires are used in nuclear power (steam generators, pressure vessels), chemical industry (reactors, pipes), energy (gas turbines, desulfurization equipment) and marine engineering (seawater desalination systems). They can stand high temperatures and resist corrosion. This makes sure the welding is reliable in extreme conditions. They are suitable for high-demand industrial situations.
Features of Inconel 690 straight weld wires
Excellent corrosion resistance: The high chromium content gives Inconel 690 straight weld wires strong resistance to oxidation, sulfidation and chloride stress corrosion cracking. They perform well in high-temperature acidic environments.
Good high-temperature performance: Inconel 690 straight weld wires can keep high strength and oxidation resistance below 980°C. They are suitable for high-temperature and high-pressure conditions.
Low hot cracking sensitivity: By improving the composition and reducing impurity elements like sulfur and phosphorus, Inconel 690 straight weld wires reduce the risk of hot cracking during welding.
Good mechanical properties: The weld metal of Inconel 690 straight weld wires has high ductility and fatigue resistance. It matches well with the base metal.
Welding process friendly: Inconel 690 straight weld wires have a stable arc and little spatter. The weld bead is uniform. They are suitable for automated welding.
Applications of Inconel 690 straight weld wires
Nuclear power equipment: Inconel 690 straight weld wires are used in key parts like the heat transfer tubes of steam generators and the sealing welds of pressure vessels. They resist corrosion from high-temperature and high-pressure water.
Chemical processing: Inconel 690 straight weld wires are used in reactors, heat exchangers and piping systems. They can deal with strong corrosive media like sulfuric acid and nitric acid.
Energy industry: Inconel 690 straight weld wires are used for heat-resistant and corrosion-resistant welding in gas turbine combustion chambers and flue gas desulfurization units (FGD).
Marine engineering: Inconel 690 straight weld wires are used in seawater desalination equipment and subsea pipelines. They resist chloride corrosion.
