During C-seam welding of shell sections on rotators, axial movement of shell or shell drifting invariably takes place. This drifting cannot be avoided. Reasons for this drifting could be geometrical inaccuracies of individual shells, inaccuracies of drive unit and idler unit alignment, etc. Even if the drive unit and idler units are aligned with each other initially, during shell loading, the argnment tends to get disturbed. In lighter shells, this drifting can be stopped by positive stoppers. However in heavier shells, due to axial drifting, tremendous pressure will get generated and this pressure will come on the positive stopper, if provided, and will break it. Ideal solution is to prevent this happening, to avoid creating such situation. This is achieved through anti-drifting arrangement. In this case also, drifting will take place which cannot be avoided. But the movement will be restricted within a band of "+ - 5 mm". Seam will keep floating forward and backward within this range.

Motorized Material Transfer Wagon Trolley is meant for transferring material from one bay (shop) to another. Wagon Trolley moves on Indian standard rail section grouted in ground. Material Transfer Wagons Trolleys are manufactured with load carrying capacities from 5MT to 500 MT capacities as per customer's requirement.

Capable of rotating through 360o and lift to certain height of around 2 meters. The fixture needed to be capable of allowing a robot full access around the component parts.

Hydraulic anti-drift system was developed and manufactured for one of the largest boiler manufacturing companies in india. This system was designed to sense and correct drifting of shells automatically.

Seam tracking systems deliver precise automated weld joint tracking for submerged arc and GMAW and FCAW arc welding processes. Ideal for repetitive welding applications, these systems are recommended over manual and semiautomatic welding to improve weld quality. A range of standard systems or customized solutions are available to meet the requirements of many tough production environments.

Cross slides can be used with Seam Tracking and Motorized Slide systems. Cross slides are precise vertical and horizontal torch-positioning devices. The slides incorporate ball bearing wheels that ride on hardened steel rails mounted on an aluminummild steel base structure. Totally enclosed DC AC gear motors drive the covered ball screws.
