How to brew a cast iron stove on the stove

In the old days, cast iron was often used for stoves in the oven. When cracks appeared on it, they could simply be thrown away, and in this place put another - a new one. But with the development of technology, stoves were thrown out of the house, and cast iron stoves, which were not in demand at all, became a shortage in the market. Therefore, those not many people who have cast iron left on the stove wonder: how to weld cracks?

How to make a cast iron stove

There are many ways to weld cast iron in general, it is an inverter, cold welding, hot welding, half-hot.

Cooker preparation

Preparation of cast iron before the welding process is required. For cleaning, a grinder with a petal circle is used. As soon as the rust layer is removed, you need to treat the plate with a solvent for degreasing. In the preparation process, you need to pay attention to:

1. Hairpins. There are two types of welding using supporting elements, and without them.
2. Cutting edges.
3. The use of special electrodes.

Selection of brewing method

Only three methods for welding cast iron:

1. Hot. It is considered the main and most suitable for this type of material. The essence of welding is that before you start working with electrodes, you need to warm the metal to a high temperature.
2. Half hot. This method is identical to the previous one, except for the heating temperature, it should be less.
3. Cold Characterized by a large number of technological processes, but not involving heating.

Brewing a Cast Iron Plate: Step-by-Step Instructions

Before you start welding cast iron at home, you need to properly prepare the metal and follow the step-by-step instructions:

1. Edging is performed under 45⁰if the plate plate is thick. Such a procedure can be carried out using a grinder or grinder. The crack on cast iron is initially treated with an abrasive disk, and after that the ends of the defective area are drilled.
2. The graphite base is placed under a thin material (3mm). The molten metal will not leak from the back during welding.
3. Metal must be cleaned of dust, rust and debris. After that, it must be heated with a blowtorch or other equipment.
4. The welding process begins as soon as the required temperature is reached. Fix the sides of the plate with the help of tacks.
5. It is not recommended to allow lateral vibrations during the first weld, it is very fast. The seam is adjusted on several sides if the length of the plate exceeds 100 mm. This procedure will help to avoid overheating of cast iron on the one hand.
6. If the plate is thick, then it is necessary to make a seam in several moves. For the best fight of cast iron, after the first straight seam, oscillatory ones are made.
7. After each seam, slag separation is done.

Important! As soon as the welding process is completed, the seam must be covered with sand until the product cools completely.

The process of welding such metal at home using an inverter is very successful.
