Standard for steel welding wire, mainly nickel-clad flux-clad electrodes. Which is often abbreviated as “nickel” wire, commonly used for welding cast iron. without preheating and can be machined. Welding is faster than gas welding. In this standard, it is specified that only the flat position can be welded.
udo.co.th The equipment center, grinding machines, grinding wheels and various tools for welding work of all kinds. We have a team of highly experienced professionals to give advice and consultation to all customers.
However, some welding electrodes may be able to be welded in other positions. Therefore, nickel welding electrodes in this standard are not required for SMAW welding.
This electrode can be used to bond gray cast iron to gray cast iron itself. or other ferrous metals or non-ferrous metals and cast iron repair welding For good welding results, castings must be small or medium in size and must not be subject to severe stress or high sulfur content. Due to its lower strength and ductility than ENiFe-CI, ENi-CI electrodes can also be used to weld ductile or ductile cast iron.
ENi-CI-A electrodes are often used as a substitute for ENi-CI electrodes where the flux sheathed ENi-CI-A electrodes contain a high aluminum content. To improve welding properties, including covering and flow of slag. However, aluminum is also an alloying element and may affect the ductility.
ENiFe-CI (Nickel Iron)
This type of welding wire is an aluminum welding wire used for repair welding and welding. Various types of cast iron work This includes nodular graphite cast iron. and connecting cast iron to steel or non-ferrous metal alloys. Cast iron containing more than 0.20% phosphorus is more easily welded with this electrode than ENi-CI electrodes. Experience has also been used to weld thick materials with high weld bond, high strength cast iron and engineering cast iron.
ENiFe-CI-A (Nickel Iron)
ENiFe-CI-A electrodes are often used interchangeably with ENiFe-CI electrodes where the flux is covered by ENiFe-CI-A electrodes. Contains a lot of aluminum It is used as an aluminum welding wire to improve welding properties such as shielding and slag flow. However, aluminum is an alloying element of weld metal and may affect the stickiness
ENiFe Mn-CI (Nickel-Iron-Manganese)
This electrode contains 12% manganese added to nickel-iron electrodes to improve metallization properties and increase resistance to weld cracking.
Manganese also increases tensile stress and improves toughness. This type of electrode also provides properties similar to that of high-strength grade nodular cast iron. Better than ENiFe-CI welding electrodes ENiFe Mn-CI welding electrodes are also used for supplemental or passivation welding. wear resistance
ENiCu-A and ENiCu-B (Nickel-Copper)
This type of electrode has been used similarly to ENiFe-CI, ENiFe-CI-A and ENiFe Mn-CI electrodes. If there is a lot of melting with the workpiece, cracking may occur.
Nickel-Base Welding Wires for GMAW Cast Iron Welding
Electrodes for GMAW welding processes include ERNiFeMn-CI and ERNi-CI for welding rods for TIG and other welding processes. Not included, but this welding rod can be made into rods.
This filament winding electrode Can be used as ENiFeMn-CI flux-clad electrodes. The strength and toughness of this electrode. Suitable for welding high-strength nodular cast iron.
This spool electrode contains 99% pure nickel, but does not contain the deoxidizer used in the welding of cast iron. The weld content is mixed with high work metal. Can be decorated with machines
Gas shield for GMAW welding is used according to the manufacturer’s instructions.
Nickel-Base Welding Wire for Welding Cast Iron by Flux Cored Wire Welding Process
ENiFeT3-CI (Nickel-Iron) welding wires are designed for flux cored wire welding using self shielding gas. However, gas shielding can be used outside if recommended by the manufacturer. The composition of this electrode is similar to ENiFe-CI except that it contains a higher manganese content. Its application is the same as that of ENiFe-CI welding electrodes, commonly used for thick welding. The high manganese content of 3-5% is to increase the resistance to hot cracking, improve the strength and toughness of the weld.
In addition to welding cast iron with electric welding wire and filler wire according to this specification, there are also various copper filler wires used for brazing cast iron. which require low welding temperature, low joint strength and high ductility. Electrodes and filling electrodes for steel Casting have been defined in other specifications.
Filler Metals for Welding Unalloyed and Low Alloy Cast Iron Standard DIN 8573 Part1 January 1983 (Filler Metals for Welding Unalloyed and Low Alloy Cast Iron Materials)
This standard is a welding wire and filling wire standard for gas welding, manual arc welding and shielded gas welding processes. For welding unalloyed cast iron and low alloyed cast iron, etc.
The cast iron material to be welded is Gray cast iron , Malleable cast iron . Nodular cast iron and Alloy cast iron This standard does not include fluxes for gas welding and welding wires for sub flux welding.
