Welding pencil: overview, characteristics and application features

Over time, any material loses its properties and collapses. At the same time, problems can arise at the most unexpected moment when there is no suitable equipment for repair at your fingertips. In this case, a welding pencil is useful. It will help to make temporary repairs even in extreme conditions.

general description

The product is a rod of cylindrical shape, whose diameter is 4-16 mm, and length - 7-20 cm. In the combusted shell is placed a pre-compacted esothermic mixture, which includes solders and fluxes. They stand out after the welding pencil is heated to a certain temperature.

Thanks to this product you have the opportunity to form a welding seam in any conditions. With this tool, you can carry out not only soldering materials, but also cutting. Welding pencil is produced by different companies, and they can have different properties.

Product Advantages

It has such advantages:

• The ability to work in the absence of any power supply. It can be taken with you on a long journey, various hikes, where there are no outlets or other sources of energy.
• Carrying out repairs in home, field and even extreme conditions.
• Rapid recovery of the performance of damaged products.
• Resistance to temperatures up to 180 degrees.
• Qualitative sealing of joints.
• Versatility and small size, which makes it possible to carry the product in an ordinary bag.
• Ignition from regular matches.
• Acceptable cost.

Where is the product used?

Welding pencil can be used to connect vertical, inclined and horizontal seams. It can be used to:

1. Repair and installation work in extreme conditions.
2. Operative correction of breakages in cars, water and railway transport.
3. Welding wires from copper.
4. Repair of heating systems and pipelines.
5. Fixing of cracks and chips from bronze, cast iron.
6. Fixes the shortcomings of agricultural machinery.
7. Metal cutting in difficult conditions.

Use a welding pencil, the price of which is 60-150 rubles. And more, for the processing of such materials: steel, iron, aluminum, copper, as well as thick plastic, ceramic and slate.

Specifications

The product has the following parameters:

• Burning time of the rod (average): 20 seconds.
• Maximum combustion temperature of the product: 2200-2800 degrees.
• Allocated alloys: iron, copper, chromium, manganese, nickel, silicon.
• Seam length: 8-15 cm. This parameter depends on the type and thickness of the material that needs to be welded.

Manufacturer Overview

There are different types of pencils for welding. Each of the product brands has its own characteristics:

1. Oksal. Products of this manufacturer differ in that they have high efficiency in the absence of any energy carriers. It is enough to have a box of matches or a lighter. Work on restoring the integrity of materials can be carried out in a wide range of temperatures (-85 - +85 degrees).
2. "Nanopake." Welding pencil of this manufacturer has a low cost (150 rubles.). It can be used to repair plastic products, enamelware, slate, and other roofing materials. The pencil and wooden products, galvanized metal, are good. One element can be used up to 30 times, because it is used very sparingly.
3. Welding pencil "Extreme". This product is also used for processing metals and enamel surfaces. The cost of such a product is about 60 rubles per pc. It provides 60-70% of the strength of arc welding.

As you can see, the product has a high enough efficiency, however, it should not be used to thoroughly combine the materials.

Features of joining certain types of joints

Welding pencil (SPB, Krasnoyarsk, Moscow - this is not all the cities in which you can buy it) should be properly used. Different types of joints are processed in different ways:

• The horizontal lines are often overlapped. In this case, the materials must be laid on a metal lining, asbestos or brick. Any flammable objects in this case are not used, for example: wood, plastic.
• Vertical seams are processed using a special shelf, which is fixed slightly below the place of soldering. This helps prevent the flow of molten metal. The shelf is secured with a clamp.
• To cut metals it is necessary to melt them much more slowly than usual. In this case, you do not need a gasket under the materials.

How to use the product

Before the beginning of manipulation, you must carefully prepare your workplace. For example, those surfaces that will be amenable to processing should be pre-cleaned of rust, dirt, oxidation, paint residues, grease stains. The welded materials must be joined together very tightly. For this purpose a clamp is used.

Then the product is used in the following sequence:

1. Set fire to the pencil. The field of reaching the maximum temperature from it will begin to emit fluxes and solders, which should be applied to the damaged area.
2. The presented product terminates its burning long before it occurs to the working surface. That is, it continues to burn for some time. Naturally, at this time you should follow safety rules: do not touch the hot surface with your hands.
3. Next, try not to do anything for 20 seconds, then solder the melted mass with a pencil in the prepared surface.

Please note that any pencil work requires careful compliance with security rules. Before work, try to wear special clothes, goggles and gloves. Do not take the product with your bare hands. In addition, keep the lit pencil with pliers or other tools at some distance from yourself. This will allow you to avoid the possibility of getting burns.

Reviews of the product

Naturally, before buying the specified product, I want to know the opinion of other users about it. If you want to use a welding pencil, reviews will help you determine the manufacturer, consider the properties of the product.

However, the opinions of other users on this issue are contradictory: both negative and positive. For example, it is noted that the product emits a sufficiently strong fire, and also after its use a very unpleasant odor remains. However, a pencil for welding and should not smell like toilet water. Many consider the product useful enough that it was in a repair backpack. Excellent cutting properties of this product are noted.

However, almost all users note that it is not necessary to use it everywhere and always. It is best to apply it for partial or temporary repairs. Further, the damaged area must be repaired in a capital. It is best to use a pencil in really extreme situations, when there is simply no other way to achieve the desired result. That's all the features of the product. Good luck!
