Buy cast iron welding electrodes from VATRA LLC profitably! Welding electrodes for gray, high-strength and malleable cast iron.

Cast iron is an alloy of iron and carbon, where carbon constitutes more than 2% of the composition. The most widely used grades contain 2.5-4% carbon, 1-5% silicon, and up to 2% manganese. Conventionally, all cast iron can be divided into white and gray. White cast iron contains carbon in a bound state and is brittle.

It is not machinable and is not weldable. Gray cast iron contains carbon in the form of graphite, has a silvery-gray color at the fracture, and is weldable. You can buy cast iron welding electrodes from our company at the lowest prices.

Which cast iron electrodes to buy? Welding electrodes for gray, high-strength and malleable cast iron.

To decide on the choice and know which types of cast iron electrodes to buy, it is necessary to distinguish their welding and application characteristics. The distinctive features of cast iron are brittleness and low strength, as well as poor weldability.

Cast iron is most often welded during repair or restoration work. Various requirements are imposed on welded joints depending on the type and operating conditions of the cast iron. Two types of welding are used for cast iron – cold welding and hot welding.

Welding electrodes for cold welding are used for repairing damaged equipment and restoring worn parts. These welding electrodes do not have strict regulations and are manufactured in accordance with the technical specifications of the manufacturer.

They make it possible to obtain a weld with the required properties in the form of steel, which includes copper, nickel, and iron-nickel alloys.

During cold welding and surfacing of cast iron products, preheating is not performed. The welding technology differs from conventional welding and is carried out using short weld beads twenty-five to sixty millimeters long, with subsequent cooling of each bead to a temperature not exceeding sixty degrees. It is often recommended to forge each bead with a light hammer blow.

• 1. We recommend using TsCh-4 welding electrodes for repairing non-critical cast iron structures of small dimensions with a small volume of surfacing, where post-weld treatment is not required.
  2. MNC-2 welding surfacing electrodes are used for surfacing in industry. These electrodes contain a constantan core. The welding process is performed with a 3-4 mm diameter electrode using a thread-like seam in small sections. The part should not be overheated, so breaks must be taken to allow the weld to cool. A distinctive feature of this electrode is the composition of nickel and copper, which do not cause carbon dissolution.
  3. OZCh-3 surfacing welding electrodes are used for correcting small defects in critical structures.
  4. OZCh-4 surfacing electrodes are recommended for use in welding as a final layer in structures where parts are subject to abrasion.
  5. OZCh-2 surfacing electrodes have a copper core coated with a covering layer similar to UONI and iron powder in a 50/50 ratio based on liquid glass. After surfacing with such electrodes, the weld remains sufficiently ductile and can be processed.
