Assessment 2 – 40580/02 1a) Plain carbon steel is essentially an alloy of iron and carbon which also contains manganese and a variety of residual elements. These residual elements were either present within the raw materials used in the production process e.g. iron ore and scrap steel additions‚ or they were added in the production process for a specific purpose‚ e.g. deoxidization by means of silicon or aluminium. Hence they are called residual elements to distinguish them from alloying

Welding is the only process which is carried out to merge two metals and it is an absolute need that a person who welds should wear a helmet to protect himself from the fire sparks. The headgear protects the welder’s eyes‚ face and neck from flash burn‚ ultraviolet light‚ sparks‚ heat and infrared light. It will prevent from retina burns which lead to loss of vision. In order to avoid this unprotected exposure to the ultraviolet and infrared rays it is necessary to make use of the right helmet which
