Modern technology in a fairly short time made a rapid ascent to the heights of progress. However, many manufacturers still use more familiar materials. Arc welding is often used to connect this large number of metals used.
The presented process of connecting parts can be manual or automated. The most important goals pursued by manufacturers are the mechanization of technological processes, as well as their automation. This allows you to significantly increase the productivity and quality of products. The most complete data conversion reflects automatic arc welding. With this type of welding, the welding speed is significantly increased and the human factor is almost completely eliminated. In contrast to automatic,
manual arc welding is more time-consuming, complex and energy-intensive. A specialist welder must be highly qualified and have sufficient dexterity. Work experience in this area is also important.
The main feature that arc welding possesses is the ability to automate processes, as a result of which they pass several times faster. In turn, the mechanization of technological processes requires appropriate preparatory work. It may be necessary to install additional materials, however, arc welding does not need modernization.
During welding, special
safety rules must be observed
. The main possible hazards that may arise during the operation of the device are: optical exposure, electrical and fire hazard.
The category of optical interaction includes protection from the negative effects of an arc discharge on a person’s eyes. This is manifested in the use of special masks and glasses. Modern technology has allowed to produce a chameleon mask, which can regulate the degree of transparency. Arc welding, which is the result of using these protective equipment, produces high-quality welds under safe conditions for the welder.
Electrical safety avoids accidental contact with live parts. However, not only arc welding is a possible source of electric current. Before starting work, a thorough inspection of the insulation of wires and contacts should be carried out. It is necessary to use special protective equipment (such as overalls: bots, mittens, helmets).
It is forbidden to work under snow, rain. It is not recommended to carry out welding work in conditions of high humidity. And this requirement applies not only to street conditions, but also to the characteristics of the indoor environment. For example, boiler rooms, cellars and cooling towers.
Fire safety includes eliminating the possibility of burns with the help of special clothing, gloves, shoes, masks and protective screens.
Special safety means protection against accidental explosions, elimination of negative effects on the respiratory system, protection during high-altitude work.
