A propos du livre

Présentation de l'éditeur

Covers a number of distinct operations. In order to thoroughly understand the subject it is necessary welding intd two classes of work. or pressure welding, 2nd, autogenous The Electric A rt orse or Pressure Jf elding This term, for want of a better ime, is applied to welding processes where two pieces of metal are heated to the plastic state, then forced together by pressure or hammering to thoroughly unite them, and complete the weld. The familiar example of this is the weld which the blacksmith makes by heating two pieces of steel or iron in the forge fire, then hammering the en(K tcpgether on his anvil. A weld imilar l(i this ha been made fi a some time li the use of electricity, where two pieces of metal are heated by an electric current, then forced together to complete the weld. This prnce i known as butt or spot welding and is not the pr.ice.ss under discussion in this book. A iit ogeno us Jfeldins Tlii.- term is .-ipplied to welds which are made by heating metals to such temperature that thev will fuse together on contact, without any pressure being applied. The ditiference between autogenous welds and those fornierlv described imainly the ilitterence in temi)erature of the metal. In the autogenous weld, the metal is heated to a state of fluidity and the two pieces flow together. The use of the autogenous process, however, is not confined to the uniting of two pieces of metal. It is used to even a greater extent for adding molten metal to other metal pieces or I arts. thus building them up or tilling defects. Electric Arc Uelding Electric rc Welding is an autogenous princess. It is used both for joining metal ]arts and also for adding or building metal on such parts. In fact, when two pieces are welded together by this process, it is done b}- filling in molten metal, between the two pieces, rather than by melting the two sij that they will join. CT
