Small Bore Cladding
WELDING using computerised, fully programmable orbital welding machines on clad materials: • Stainless steels 309L and 316L • Inconel 625 and 825 • 22% and 25% Duplex • Highly trained experienced welding operators ensuring high quality, both radiographically, dye penetration test and surface finish Cladding by means of fusion welding, using alloys such as Inconel 625, and a full range of stainless steels 309L & 316L. This process of cladding is done by highly accurate and precision automatic MIG machine. Pipe internal bore cladding can be done minimum bore of 55mm to maximum bore of 400mm & above. GMMOS is specialist in internal small cladding process and has done on pressure vessel nozzle for client ie:TECHNIMONT L&T(ADMA-OPCO) SAMSUNG(GASCO) Kindly note , this is the most critical product & this welding process can be done by 2 or companies, which needs to be marketed is a very larger frame to our client.

SAW Cladding
WELDING using computerized SUB MERGED ARC (SAW) welding machines on clad materials: • Stainless steels 309L and 316L • Inconel 625 and 825 • Highly trained experienced welding operators ensuring high quality, both radiographically, dye penetration test and surface finish Cladding by means of fusion welding, using alloys such as Inconel 625, and a full range of stainless steels 309L & 316L. This process of SAW cladding is done by highly accurate and precision automatic SAW machine. Pipe internal bore cladding can be done minimum bore of 500mm to maximum bore of 1000mm & above. GMMOS is specialist in internal cladding process and has done on pressure vessel nozzle for client ie:TECHNIMONT L&T(ADMA-OPCO) SAMSUNG(GASCO).

Strip Cladding
WELDING using computerised, fully programmable electronic welding machines on strip cladding materials of ELECTRO SLAG strip DINOX309 MOL with DIMEX FLUX ES4000 , suppliers are DIMEX, BOHLER, BRAVIRIA • Stainless steels 309L and 316L • Inconel 625 and 825 • Highly trained experienced welding operators ensuring high quality, both radiographically, dye penetration test , (UT)Ultra sonic test and surface finish Cladding by means of fusion welding, using strip alloys width of 50 to 60mm such as Inconel 625, and a full range of stainless steels 309L & 316L. This process of cladding is done by highly accurate and precision automatic electronic machine. Pressure vessel internal diameter, cladding can be done minimum bore of 1500mm to maximum bore of 3000mm & above. Nowadays to reduce the cost of procuring exotic material of full thickness internal STRIP CLADDING or LINING/cladding is done with the requirement of process fulfillment and also considering the corrosion to be avoided in the internal part of PV .This process of strip cladding is in use for most of the oil & gas field equipments. Another advantage is that it prolongs the life of the equipment in avoiding corrosion. GMMOS is specialist in internal STRIP cladding process and has done on pressure vessel /shell for client ie:TECHNIMONT L&T(ADMA-OPCO) SAMSUNG(GASCO).
