Welding Cast Ductile Iron

Welding Cast Ductile Iron. Cast irons are alloys of iron carbon and silicon may have over 2 carbon and 1-3 silicon and may include specific amounts of other elements to achieve definite characteristics. Unless cared for properly the welds are prone to cracking in all the three regions.

Unless cared for properly the welds are prone to cracking in all the three regions. The objective of this investigation is to study the restoration andor hardfacing by welding of worn-out parts manufactured from pearlitic ductile cast iron. During the welding of cast irons the iron immediately adjacent to the weld metal is heated to its fusion or melting point.

Impact strength of Ductile Iron are many times that of Gray Iron.

We have available GTAW SMAW GMAW and FCAW if suitable wire is available. Bending tests were carried out on welded specimens by hammering on the extremities of the ductile iron and steel sections in order to locate the maximum. Weldable but rare as its an extensive and slow process. The work may be divided into two sections.
