Welding works - an affordable way to create permanent joints

It is difficult to imagine a construction site on which welding work is not carried out . This technology allows with a minimum of investment and in a short time to get a quality one-piece connection. It is in demand when it is necessary to install and dismantle various metal structures, lay pipelines and perform other types of work, for example, when repairing vehicles. In each case, a technology is developed that determines the procedure for the formation of a welded joint, a list of equipment and materials, and the qualifications of workers.

The human factor in this case is important. Agree that there will be a difference in the quality of the joints formed by welders 6 and 4 digits. In the second case, even with the passage of visual control, it will be possible to identify defects visible to the naked eye. That is why welding work must be carried out exclusively by qualified personnel who have received appropriate training, and therefore have the necessary skills. With this approach, all control stages will be passed, and the formed connection will withstand the loads applied to it for a long time.

It is worth noting that welding can be of various types. The most widespread are, of course, electric and gas, but if necessary, you can also resort to ultrasonic, laser and cold. In the latter method, welding operations are carried out at a temperature below recrystallization. In this case, the compound is formed as a result of deformation of the metal arising at mechanical pressure. An example is spot welding. For its implementation, you need to have special equipment - the so-called "mites".

Also, welding operations can be performed in different planes and be of different types. The connection, for example, may be butt, spot and suture. For each specific case, you must choose the best option. If welding is carried out over the whole plane of touch, then we are talking about a junction connection, in some places - a point connection. The latter option is often used at the preparatory stage of the design. It allows to ensure the correct relative positioning of the connected elements. After this, a continuous weld seam is formed, consisting of overlapping or non-overlapping individual points. In the case of the first version, a durable and sealed connection is obtained.

If we talk about how much welding work costs, then no one can give a definite answer. For the formation of metal structures from the same alloys, it is possible to use various electrodes that will be similar in chemical composition, but will differ in value. The price per kilogram of such materials often indicates their quality. Using the products of only proven and well-known brands, you can perform welding works of any complexity. True, if qualified personnel are involved.
