Oxy-Acetylene Welding of Steel & Iron There are many different varieties of steel, but from a welding standpoint they may be classified by their carbon content. Those having a high carbon content are called hard steels; those with a low carbon content, soft steels. Wrought iron may be treated the same as mild or soft steel. To be sure, there

Oxy-Acetylene Welding of Cast Iron The welding of cast iron with the oxy-acetylene flame is comparatively easy, if attention is paid to some simple rules. The cast iron in common use is known as. “gray;” it is quite soft, easily machined and has a lower melting point than wrought iron or steel. It contains two kinds of carbon, combined and
Read more →Welding Steel. (1) General. The term “steel” may be applied to many ferrous metals which differ greatly in both chemical and physical properties. In general, they may be divided into plain carbon and alloy groups. By following the proper procedures, most steels can be successfully welded. However, parts fabricated by welding generally contain less than 0.30 percent carbon. Heat increases

(1.6 mm) thick can be made satisfactorily by flanging the edges at the joint. The flanges must be at least equal to the thickness of the
