We are pleased to announce that, our HF-55M Seamless Flux Cored Wire approved by DNV and  4Y50 grade.

Within FCAW , seamless cored wires offer optimal protection against moisture reabsorption.

During use, moisture cannot penetrate into the filling since there is no closed seam running over the wire length. This extremely low level of diffusible hydrogen prevents the weld from hydrogen induced cracking or cold cracking.

HG-1F / E71T-1C is a seamless rutile flux cored wire applicable for all-positional welding with
100% CO2 shielding gas.

Thanks to its unique seamless structure, HG-1F / E71T-1C generates low spatter and has excellent impact properties in low temperature.
These properties make HG-1F / E71T-1C the perfect seamless cored wire for industries such as shipbuilding, steel construction, bridges, offshore, pipes, and pressure vessels.

A5.29 E81T1-Ni1M-J is a type of flux-cored wire used for welding. The designation “A5.29” refers to the American Welding Society (AWS) specification for low-alloy steel electrodes for flux-cored arc welding. The “E” in the designation indicates that it is an electrode, and the “81” indicates the minimum tensile strength of the weld metal in ksi (thousands of pounds per square inch).

The “T1” indicates that the electrode has a rutile (titanium dioxide) flux, which provides good weld bead shape and slag release. The “Ni1M” indicates that the wire has a nominal composition of 1% nickel and 0.5% molybdenum, which provides good toughness and resistance to cracking in the weld metal. The “J” at the end indicates that the wire meets the impact toughness requirements when tested at -40°C.

Flux-cored wire is a type of welding wire that contains a flux core, which provides shielding from the atmosphere during the welding process. This allows for welding in outdoor or windy conditions, where solid wire and gas shielding may not be practical. Flux-cored wire is also often used for welding thicker materials, as it can provide deeper penetration than solid wire.

AWS A5.18 E70C-6M is a type of metal cored wire used for welding. Metal cored wires are similar to flux-cored wires in that they have a tubular design, but instead of a flux coating, they have a metal powder filling. This metal powder filling contains various alloys and other materials that help to improve the welding process.

This type of wire is commonly used for welding carbon and low-alloy steels, especially in applications where high productivity and good penetration are desired. The metal powder filling helps to increase the deposition rate, resulting in faster welding speeds and higher productivity. The wire also produces a smooth, low spatter weld with good bead appearance.

AWS A5.18 E70C-6M is a type of welding wire that conforms to the American Welding Society (AWS) specification A5.18. The “E70C-6M” designation indicates the specific type of wire, where “E” stands for electrode, “70” refers to the minimum tensile strength of the weld metal, “C” indicates that it is a composite electrode (i.e., metal-cored wire), “6” refers to Chemical Composition Requirements for Weld Metal from Composite Electrodes, and the “M” means that it is suitable for welding with 75%–80% Ar/balance CO 2 (M21) gas.

Seamless flux-cored wire for hardfacing is a type of welding wire used to create wear-resistant coatings on metal parts. Hardfacing is a process in which a layer of wear-resistant material is applied to a metal surface to increase its durability and lifespan.

Seamless flux-cored wire for hardfacing is designed to be used in applications where a high degree of wear resistance is required, such as in mining, construction, and manufacturing industries. The seamless design of the wire allows for a consistent and uniform deposit of the welding material, resulting in a smooth and uniform surface finish.

The flux in the wire provides shielding from the atmosphere and produces a slag that covers the weld, protecting it from contamination. The hardfacing material is typically made of alloys such as chromium, tungsten carbide, or cobalt-based alloys, which are chosen for their high hardness and wear resistance.

It is important to use the correct type of hardfacing material and welding parameters when using seamless flux-cored wire for hardfacing to ensure a high-quality and long-lasting coating. The manufacturer’s instructions and recommended welding parameters should always be followed for optimal results.

What is ISO 14700 standard？

ISO 14700 is a standard developed by the International Organization for Standardization (ISO) that specifies requirements for the deposition of metallic and other inorganic coatings on metallic substrates by various thermal spray processes. This standard covers the following thermal spray processes:

• Flame spraying
• Electric arc spraying
• Plasma spraying
• High-velocity oxy-fuel spraying (HVOF)

ISO 14700 provides guidelines for the selection of coating materials and their properties, the preparation of substrates, and the control of the thermal spray process. It also covers the testing and evaluation of coatings to ensure that they meet the required quality and performance standards.

The purpose of this standard is to ensure that thermal spray coatings are applied consistently and reliably to provide the required level of protection, such as wear resistance, corrosion protection, or thermal insulation. Compliance with ISO 14700 can help ensure that thermal spray coatings are of high quality and will perform as intended in their intended application.

ISO 14700 is widely recognized as a global standard for thermal spray coatings and is used by many industries, including aerospace, automotive, energy, and defense.

What is ISO 14700 : T Fe8 seamless flux cored wire？

ISO 14700 T Fe8 is a code that refers to a specific type of thermal spray coating material. The “T” in the code stands for “Thermal Spraying,” indicating that the material is intended for use in thermal spray processes, such as flame spraying, plasma spraying, or HVOF spraying.

The “Fe” in the code refers to the primary element in the coating material, which in this case is iron. The number “8” indicates the percentage of the primary element in the material, which in this case is 8%.

Therefore, ISO 14700 T Fe8 specifies a thermal spray coating material that contains 8% iron as the primary element. The specific properties of the coating material, such as its hardness, wear resistance, and corrosion resistance, will depend on the specific composition of the material and the thermal spray process used to apply it.
