Welding is a compound that is carried out using the intermediary connection between the welded parts by heating and deforming elements. In simple words – the connection of two or more parts together, splitting the material under the influence of high temperature. This method was popular for a very long time, but a certain alternative arose with the transition to the new century, which, according to experts, is more durable. The main disadvantages of welding are the distortion of the product, which leads to loss of strength.
Today, the most popular ways to relieve mechanical stress are: heat treatment, low -frequency vibration processing, ultrasound processing and others.
Heat treatment can not always be used. For example, it does not interact well with thermally processed metals and brittle structures. For heat treatment, you also need special equipment, which entails financial costs and other inconvenience.
Ultrasound processing creates a cyclic and pulse voltage, which acts at a depth of up to two millimeters. It is proved that after this type of processing, the risk of corrosion is significantly reduced.
Low -frequency processing is popular in that it is suitable for both overall objects and for very small structures. It is several times more effective than ordinary heat treatment, but it is very important to control the entire process.
