Plate Joining Equipment

This stage is used to adjust alignment and join main plates of ship flat blocks which are cut CNC cutting machine. It controls alignment, gap and step between the plates to join them by tack welding.
 

Butt welding equipment - front side welding

This stage is used to weld main plates which come from the previous stage(Plate Joining) by Submerged Arc Welding (SAW). Multi-pole welding enables to increase productivity. It allows to weld up to 25mm thickness by tworun technique as square butt joint.

Turn Over Stage

There are two types of turn over system for steel plate which are CTO(Crane Turn Over) and FTO(Flip Turn Over) system. CTO use overhead crane and FTO use flip boom for turning over steel plate. These systems are used for turning over steel plate which comes from front side butt welding stage and pass it to back side butt welding stage. One of these systems can be chosen after considering factory condition and work type preference.

C1. Turn over stage - crane turn over system

C2. Turn over stage - flip turn over system

Butt welding equipment - back side welding

After turn over of plate, the opposite side of welding will be accomplished by this equipment.
 

Longitudinal transfer car

All the longitudinal members like flat, angle, tee, bulb stiffeners are supplied to Longitudinal Fit up stage by this equipment.
 

Longitudinal fit-up equipment

This equipment is used to fit up of longitudinal stiffeners by tack welding on the main plate which comes from the previous stage (Butt welding stage).
It uses magnetic controller and hydraulic cylinder to control span, angle and gap between main plate and stiffener to put them on the designated location.

Multi pole longitudinal auto welding Equipment

This equipment is used to weld longitudinal stiffeners fitted on the main plate. Mostly welding will be done by FCAW process and both side welding can be done simultaneously. Number of welding pole depends on the customer's requirements up to 40 poles.

Block transfer car

It transfer flat blocks from one stage to next stage according to production work flow. It can lift maximum 400 tons single block by combining two (2) rows of transfer car. This equipment shall in installed under the fixed working table, controlled by remote controller. Cable pendent also can be used for emergency case.

Pulling winch

This equipment is used to fit the transvers members into block by pulling. This process called by Slit method. Main benefit of Slit method is productivity, time and cost for fabrication of block. (No need to install collar plate)

Block lifting system

This equipment is located the end of block assembly line and used to load out of completed block from workshop.
It lifts up the block to transport by transporter.
