TECHNICAL AND TRADE INFORMATION WELDING OF CASTIRON 5. Malleable Cast Irons Malleable cast irons, which include the white heart and black heart irons, are formed by heating white iron for a set period of time. Malleable cast irons have a higher tensile strength and better ductility than grey cast iron and will bend or deform before breaking as well as standing shock better than grey cast iron This electrode is made from a Nickel-Iron core wire and produces a ductile, machineable weld deposit with the extra strength required for welding SG (Spheroidal Graphite) irons. Typical Applications For repair and build-up of SG irons and all standard grades of grey cast iron, malleable iron, austenitic cast iron and some grades of meehanite cast iron.

Preheating the cast iron part before welding will slow the cooling rate of the weld, and the region surround the weld. It is always preferred to heat the entire casting, if possible. Typical preheat temperatures are 500-1200 degrees F. Don’t heat over 1400 degrees F since that will put the material into the critical temperature range. Preheat the part slowly and uniformly.

Malleable Cast Irons Malleable cast irons, which include the white heart and black heart irons, are formed by heating white iron for a set period of time. Malleable cast irons have a higher tensile strength and better ductility than grey cast iron and will bend or deform before breaking as well as standing shock better than grey cast iron

The equivalent carbon content concept is used on ferrous materials, typically steel and cast iron, to determine various properties of the alloy when more than just carbon is used as an alloyant, which is … known as eutectic cast iron. Cast irons with carbon less than 4.3 % are known as Cast irons with carbon less than 4.3 % are known as hypoeutectic and those having more than 4.3% are called hypereutectic cast

Sifbronzing ‘A Guide To The Technique’ Technical advice in the original SifTips style which started in 1932 Sifbronzing is an almost universally recognised way of describing the low temperature bronze welding of sheet steel, cast iron and other metals. The Sifbronze Technique For successful ‘sifbronzing’ or ‘bronze welding’, parts must be thoroughly cleaned and degreased and to cnm non- machinable weld on cast iron characteristics joining surfacing repair technical data non – machinable weld

Welcome to the Weldability Sif Technical Knowledge Database. We answer many technical questions daily in assisting customers with selecting and using our products in their applications. Preheating the cast iron part before welding will slow the cooling rate of the weld, and the region surround the weld. It is always preferred to heat the entire casting, if possible. Typical preheat temperatures are 500-1200 degrees F. Don’t heat over 1400 degrees F since that will put the material into the critical temperature range. Preheat the part slowly and uniformly.

• Low and slow is the key to a sound cast iron weld. • You can use a mild steel patch over large holes, the 77 and 72 will weld the steel to the cast iron. Malleable Cast Iron (GT –DIN) • Malleable irons are cast white. • There are two types of malleable iron. • Application : automotive parts. • Malleable irons have a good weldability. agricultural components. . valves etc. machinability and ductility.

FIELD WELDING AND CUTTING DUCTILE IRON PIPE their weldability. During the welding of cast irons, the iron immediately adjacent to the weld metal is heated to its fusion or melting point. After welding, the entire heat-affected zone cools very rapidly. During this heating and cooling, some of the graphitic carbon dissolves and diffus- es into the iron, and, as a result, carbides tend to G.

The Sifbronze Technique For successful ‘sifbronzing’ or ‘bronze welding’, parts must be thoroughly cleaned and degreased and to TIG Welding Cast Iron. When TIG welding with cast iron, a nickel wire is the only real option available for this job. It can be expensive, although, the TIG process can provide a strong and clean weld on most cast iron jobs. It’s also possible to cold-weld (skip pre and post heating stage) cast iron with TIG, if you are using the correct gas, wire and settings. This process deserves an

WIA’s comprehensive range of arc welding electrodes includes: general purpose welding electrodes, hydrogen controlled welding electrodes, iron powder welding electrodes, cellulose welding electrodes, stainless steel and cast iron welding electrodes and gouging and cutting welding electrodes. One of the most popular arc welding electrodes in WIA’s range is the Austarc 16TC low hydrogen TIG Welding Cast Iron.
