Many works on the construction or repair site of a standard residential building, when laying a gas or water pipeline, in the automotive industry cannot be imagined without the stage of joining metal structures using welding. Airplanes, ships, submarines, trains and many other means of transportation were created when it became possible to join sheets of iron into a single whole using welds. Even minor home repairs, such as installing a cornice or plumbing, are only possible because seams were previously laid to hold the frame together. Construction expertise quite often faces the need to answer the question of how well the welding of metal structures was done. This work requires great care, because the life and health of future residents of the house depends on it.
There are several types of welding:
-
- electro-gas;
- termite;
- electron beam.
Gas or electric arc welding with a wire acts as a kind of glue when synthesizing two or more metal parts.
Specialists highlight the following positive aspects of using welding wire:
-
- the reliability of a weld that can withstand high pressure;
- economical consumption of consumables;
- long and continuous burning of a high-temperature arc.
Choosing the right welding wire
To choose a wire for welding, you need to know what material it will weld with. For example, low-carbon steels are best connected using wire marked SV-08-GS and SV-08-G2S. While non-corrosive steels and aluminum alloys can be alloyed with almost any wire.
The thickness of the selected wire also depends on which part of what thickness is planned to be welded, as well as what kind of welding unit the work will be done. As shown by an independent examination and anonymous polls of professionals, most specialists weld products in two stages, which is unacceptable for safety reasons. However, this is because the same wire diameter cannot be used over the entire length of the weld. Most often, wire for welding with a thickness of 0.8 to 1.6 mm is in demand.
