Weld Overlay Clad Process
RocCLAD is a metallurgical bonding technology of two kinds of different metals. It is the 100% metal fusion technique.
RocClad makes overlay welding on most carbon, low alloy, chrome moly, stainless steel and other steels with variety of corrosion resistant alloy including Inconel®, Incoloy®, Monel®, Hastelloy®, stainless steel and hard facing materials. Benefiting from our advanced DSP or PLC controlled welding stations and optimized producing process, we offer low dilution of alloy deposit. Real time video monitoring and recording system ensure perfect tie in and weldpath. Iron (Fe) content of the Inconel 625 cladding layer can reach less than 5% in the surface 1mm below the top surface.
HRB Clad Fitting Process
RocCLAD CRA clad pipe fittings are made of weld overlay clad pipes or clad steel plates, pipe/plate forming, automatic welding equipment, 100% RT after welding, pickling&passivation, and bevelling process are adopted to ensure a high degree of automation in the whole process. The types of products are elbows, tees, reducers, caps, etc. The diameter range of welded pipe can be 16”~80”, wall thickness 9.27mm~90mm.
