The Welding World – Your source for welding information We live
in a world full of elements and materials. These materials form
the core basis of today's engineering processes. From building
navy ships to the generation of electronic chips, materials
continue to play a significant role in the lives of the
inhabitants of the earth. Materials such as metals play a
significant role in making equipment and gadgets that add
comfort to life. However, these materials need to be crafted to
meet certain specifications. The art of developing these
materials according to certain specifications and codes is
normally what many refer as engineering. Engineers perform
various functions for example, joining two or more metals of
same or different types permanently to come up with equipment or
facilities. This is known as welding. Most of today's equipment
comprises of two or more metals joined permanently. For metals
to join they must be melted, and then the molten parts mixed and
allowed to cool. People working in the weldi
