Welding argon iron - perfect for home

How to weld cast iron - features of formation of stitches

achieve a quality weld on cast iron is problematic.This is due to a number of changes in its structure, taking place during the heating process.Therefore, it is considered a material that lends itself to welding of difficult, especially if the iron is held in the home welding.

With all the features of a given metal, argon welding is considered one of the most reliable methods of obtaining high quality welds on cast iron.This technology makes it possible to make a seam, similar in its properties with the base material.

semiautomatic welding cast iron with argon provides a gradual warming and cooling components.As a result, the metal structure in the formation of graphite occurs, which makes it more pliable.Welding work is carried out with the use of fluxes and rods made from graphite materials.

iron welding technology - industrial approaches

Modern iron welding technology provides two methods for welds: with the help of warm-up and using cold welding.In modern industrial practice more than three dozen welding cast iron without preheating.The most commonly used three species:

1. using steel electrodes.
2. using electrodes with rods made of nonferrous metals.
3. with electrodes small section with a minimum carbon content.

For those interested in how to weld iron, will be curious to learn and that in an industrial environment for cold welding, mainly, the following electrodes:

1. OZCH-2 - mednosterzhnevye electrodes with a special coating;
2. IPM-2 - electrodes with a rod, which is composed of nickel, copper, iron and manganese.

Suture metal, which is obtained as a result of welding electrodes brand OZCH-2, quite well treated.The only drawback of such electrodes - it is their high cost.electrodes cost IPM-2 is slightly lower, and in addition, they can be made at home.

argon welding of cast iron - the best option for home use

For welding with maximum uniformity of metal is widely used inverter welding cast iron.This method is used when using manual arc welding with a connection to the transformer-rectifier.

When working with an inverter using electrodes made of iron bars with a thin layer of coating and up to half a meter.For ferritic weld metal type used local heating to 300oC.

most difficult to apply, according to experts, considered steel electrodes with graphite coating.The seam which is formed during operation such electrodes, characterized by its inhomogeneity often results in cracking.Therefore, in the industrial production they are used rarely.

As can be seen from all the above, only semi-automatic argon welding cast iron allows to obtain high-quality welds.To perform such works are used electrodes made of cast iron plates or cored wire.

also various fluxes and additives commonly used for welding with argon semiautomatic.If you want to learn more about how to weld iron argon, video on the web page will help you become familiar with the process in more detail.
