Many people prefer living in a private houseLiving in an apartment. However, in this case it is necessary to spend more time on the maintenance of various structures and constructions. If staying in a private home and then there is a need for metal welding. Many aspire to master this thing, not to turn to specialists and to avoid high costs. To work need to purchase a welding machine and electrodes. Consumables can be found on the page, but how to choose the most suitable for your purposes? In this article we will look at popular types of electrodes and their key features.
Variety of welding electrodes
Products are usually divided into two great classes -melting and non-consumable. In the first case, the electrodes are made from wire which has a particular outer covering, which ensures stability of the welding arc. In addition, they help to protect the base metal, preventing the ingress of slag on the surface spray and different gases. To perform the processing of copper or stainless steel electrodes are used, made of special alloys. To perform argon welding is best suited non-consumable products.
Depending on the core wire coatingthe electrodes are divided into basic and rutile. In the first case it is possible to obtain high quality welds. They will be resistant to the appearance of cracks and high crystallization resistance. Basic electrodes are widely used for the production of joints in critical areas, the operation of which will be carried out in difficult conditions. At the same time, they have their weaknesses. For example, the porous structure, the same effect can occur when errors in exhibiting an arc can be formed when handling wet coating.
For low-carbon weld metaluse with rutile electrodes. They are able to get high effect when working with DC and AC. This welding process is not accompanied by the formation of spray. Electrodes with rutile can be used for welding soiled and rusted metal.
As you can see, there is a huge variety ofwelding electrodes. Each species has its own peculiarities. Acquainted with them, you can choose the best option for their own purposes and conditions of use.
