Modern technologies in a fairly short period of time have made a rapid ascent to the heights of progress. However, many manufacturers still use more familiar materials. Arc welding is often used to join these many metals in use.
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 productivity and product quality. Most fully these transformations are reflected by automatic arc welding. With this type of welding, the speed of welding operations is significantly increased and the human factor is almost completely eliminated. In contrast to automatic, manual arc welding is more labor-intensive, complex and energy-intensive. The welder must be highly qualified and have sufficient skill. Work experience in this field is also important.
The main feature that arc welding has is the ability to automate processes, as a result of which they are 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 to be upgraded.
Special safety regulations are required during welding work. The main possible hazards that may arise during the operation of the device are: optical impact, electrical and fire hazard.
The category of optical interaction includes protection against the negative effects of an arc discharge on a person's eyes. This is manifested in the use of special masks and glasses. Modern technologies have made it possible to produce a chameleon mask that can adjust the degree of transparency. The arc welding that results from these protections 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 exposure to 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: boots, gloves, helmets).
It is forbidden to work under snow, rain. It is not recommended to perform welding work in conditions of high humidity. And this requirement applies not only to outdoor conditions, but also to the characteristics of the indoor environment. For example, boiler rooms, basements andcooling towers.
Fire safety includes avoiding the possibility of burns with the help of special clothing, gloves, shoes, masks and protective screens.
Special safety means protection against accidental explosions, exclusion of negative effects on the respiratory system, protection during high- altitude work.
