Manufacturing1st Bay
1st Bay is dedicated to manufacturing of Heavy duty Steel Profiles that includes I-Beams, H-Beams, L, T and Box Girders section up to 21 meters in length. The Profiles are manufactured under automated line giving higher throughput and controllable quality.
The welding process is Submerged Arc Welding. 2nd Bay
2nd Bay is reserved to support value addition, such as stiffener & attachment fabrication, drilling, coping, sand blasting and painting on the Profiles.
The Manufacturing process consists of the following:
Welding ProcessThe Welding process is Sub merged Arc Welding. The weld deposits are done with electrodes that correspond to the base material as far as composition and tensile properties are concerned and meeting with the requirements requested. Welding is done using a vertical v-weld, except on L-sections WL-3 where the backing weld is a half K-weld or in other words, the web is joined before welding. The maximum a-size is 13 mm (Leg size 18.3 mm), using one pass welding. Larger a-size can be assembled using multi-pass welding.
For normal use, the a-size is calculated thus: CapacityThe capacity of the Profile Welding Plant is depended on the product-mix and the production process in use. Optimum product-mix yields the following figures: Day 8 hour shift working 1600 tons / monthThree 8-hour shift working 57,000 tons / year When using automatic welding lines under optimum conditions, the plant is capable of producing some 2000 meters one layer weld per shift. |
