Welding Ductile Iron Pipe To Steel. The clamps should be made of flat bars which should be split into two equal parts. Black steel pipe can be welded utilizing any welding technique used for steel. Ductile iron7 shrinkage Gray iron 10. This incorporates MIG motion center TIG and stick curve welding.
Regardless you should be able to weld any of these together with steel but you dont want a weak weld because you thought you had cast iron when you really have something with a higher melting temperature. The best option is to not weld unless you absolutely have to. Ductile iron pipe joints come in 18-to 20-foot lengths which are much easier to handle in the field than 40- to 50-foot steel joints. The friction welding of ductile iron specimens was conducted using AISI 321 stainless steel as an interlayer. Ductile iron is more susceptible to welding stresses and more likely to crack while welding or during cooling. Of the Ductile Iron or alloy steel connecting piece to be welded should be cleaned and ground to bright metal.
Bend both ends of each part at 90 and make a hole on each end.
Of the Ductile Iron or alloy steel connecting piece to be welded should be cleaned and ground to bright metal. Regardless you should be able to weld any of these together with steel but you dont want a weak weld because you thought you had cast iron when you really have something with a higher melting temperature. With correct preheat control of interpass temp plus furious peening of the weldment ductile CI usually welds well to mild steel. The process simply involves fusion of the base metal and filler rod by heat generated from an oxyacetylene flame. Weld Joint Design Most weld joint designs commonly used for welding carbon steels are generally suitable for welding Ductile Iron butt welding is not recommended. Yes cast iron can be welded to steel.
