Leader in Manufacturing Process Steam & Power Generation Equipment Cheema Boilers Limited, popularly known as CBL is a trusted name in the field of Indian Boiler Industry. It is known for itscommitment, competence and compliance. CBL was established in the year 1999 to providecomplete solution to steam generation needs. The company's origin in the boiler industry goes back to founding of it's sister concern Cheema Engineering Services (P) Limited engaged inmanufacturing of Steam Boilers, Pollution Control equipment, Fluidized Bed Conversion andenergy saving devices since 1991.It's visionary Mr. Harjinder Singh Cheema, currently CBL Managing Director along with his three brothers, now CBL Directors started this company with Boiler services and very soon CBL movedto manufacturing of full-fledged Process Boilers. Presently company is manufacturing all types of boiler to meet the requirement of process and power industry.CBL has got its own manufacturing facilities at Kurali 25 kms from Chandigarh, near Ropar andCorporate Office at Mohali, (Chandigarh).
ARC Welding : Arc welding is a type of welding that uses a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point. They can use either direct (DC) or alternating (AC) current, and consumable or non-consumable electrodes. The welding region is usually protected by some type of shielding gas, vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated. First developed in the late part of the 19th century, arc welding became commercially important in shipbuilding during the Second World War. Today it remains an important process for the fabrication of steel structures and vehicles. SAW Welding : Submerged arc welding (SAW) is a common arc welding process. The first patent on the submerged-arc welding (SAW) process was taken out in 1935 and covered an electric arc beneath a bed of granulated flux. Originally developed by the Linde - Union Carbide Company.[citation needed] It requires a non-continuously fed consumable solid or tubular (flux cored) electrode. The molten weld and the arc zone are protected from atmospheric contamination by being "submerged" under a blanket of granular fusible flux consisting of lime, silica, manganese oxide, calcium fluoride, and other compounds. When molten, the flux becomes conductive, and provides a current path between the electrode and the work. This thick layer of flux completely covers the molten metal thus preventing spatter and sparks as well as suppressing the intense ultraviolet radiation and fumes that are a part of the shielded metal arc welding (SMAW) process. FCAW Welding : Flux-cored arc welding (FCAW or FCA) is a semi- automatic or automatic arc welding process. FCAW requires a continuously-fed consumable tubular electrode containing a flux and a constant-voltage or, less commonly, a constant-current welding power supply. An externally supplied shielding gas is sometimes used, but often the flux itself is relied upon to generate the necessary protection from the atmosphere, producing both gaseous protection and liquid slag protecting the weld. The process is widely used in construction because of its high welding speed and portability.
