It is a dangerous process and precautions must be taken in order to avoid electric shock, burns, vision damage, exposure to UV radiation, and inhalation of toxic fumes and gases. Welding process traces its historic development from the ancient times. Therefore, this paper will delve into the changes technology has made in welding from the ancient times to the present.
Welding traces its roots from the Bronze Age and the Iron Age. During the Bronze Age, small round golden boxes were made by pressure welding of lap joints together. It is believed that these golden boxes were made over two thousand years ago. Currently, the golden boxes have been put on exhibition at the National Museum in Ireland. On the other hand, during the Iron Age, people from the Eastern Mediterranean and Egyptians learnt the art of welding pieces of iron together. They made tools and weapons using forge welding operations. The art of blacksmithing developed to a high degree during the Middle Ages period. Several tools and weapons made from iron were welded by hammering. Blacksmithing entails working with extremely hot steel, a hammer and an anvil to make items. After the steel has been heated, it becomes malleable making it easy to punch and twist. It is the twisting and punching that shapes the metal. After shaping, it is cooled to harden the shape. Sometimes it is taken back to the fire for reheating for further shaping and bending. While doing this, a blacksmith should use tongs handle the metals since they are extremely hot to be handled by bare hands.
The process of forging metals and blacksmithing was extremely dangerous. This is ascribed to the fact that the blacksmith’s fires can be very hot, and it is mandatory to stoke them constantly in order to maintain the high temperatures. Therefore, blacksmiths had to observe caution while working in order not to burn their bodies or places of work. Secondly, blacksmiths

Welding is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence. This is often done by melting the work pieces and adding a filler material to form a pool of molten material that cools to become a strong joint, but sometimes pressure is used in conjunction with heat, or by itself, to produce the weld.
Consequently, the creation of knowledge and the application of such knowledge in work practices has become a dominant theme in recent studies of education and training. These changes have influenced the nature of workplaces. We now talk of "learning organizations" and "learning factories" which advocate a holistic approach to training based around knowledge which is of different forms--technical, communicative, and emancipatory (Starkey, 1996).
