Wuxi JACK T Beam Production Line, Highly Efficient Machine Tools Group for Shipbuilding and Steel Structure

A. Extensive Use of 3 in 1 T Beam Fabrication Machine:

1. T Beam is important raw material in Steel Structure and Shipbuilding Industry. Unlike H Beam, which has 2 types of hot rolled type and welding type, T Beam only has one type of welding produced, which should be manufactured from machine line group, or individual equipment of T Beam Assembly Machine:
2. Wuxi JACK 3 in 1 T Beam Fabrication Machine produces welding T Beam: (Fig.1)

B. Two Major Applications of T Beam Production Line and Related Machines:

Customers having requirement on welding T Beam production come from two industries: Steel Structure and Shipbuilding, which has certain different specific requirement on specifications of produced T Beam, and hence production process technology:

1. Multi-Head T Beam Welding Machine for Shipbuilding Use:

1) Welding Technology in Shipbuilding Purpose Multi-Head T Beam Welding Machine:

a) In Shipbuilding field, the welding seam should have higher anti-impact IK value than normal, which is accomplished with CO₂ gas shielded welding:
b) CO₂ gas shielded GMAW welding on T Beam with strong light and heavy fume: (Fig.2)

c) Besides, to raise product efficiency, multi-head T Beam Welding Machine is often equipped with several (4 to 5) pieces of welding torches, to complete welding on several pieces of T Beams simultaneously:
d) 4 pieces of T Beams are being welded in Wuxi JACK multi-head T Beam Welding Machine: (Fig.3)

2) Edge Rounding Machine in Shipbuilding Use T Beam Production Line:

a) Another crucial important difference between Shipbuilding and Steel Structure use T Beam for its production technology is, after steel plate being cut from CNC Strip Plate Cutting Machine, and before being assembled and tack welded in T Beam Assembly Machine, the end plate (Horizontal plate) and stiffener (Vertical plate) should have its edge rounded and trimmed, in RH800 to RH1000 Edge Rounding Machine;
b) This is because that, T Beam used in Shipbuilding always work in humid environment with high moisture, which should be strengthened for its painting adhesive capability. This is accomplished with edge rounding operation;

3) Finished Workpiece Specifications of Shipbuilding Purpose T Beam Production Line:

Size of T Beam used in Shipbuilding is somewhat smaller than those for Steel Structure:
a) Height of stiffener (Vertical plate) is usually in the range of 300mm to 1000mm;
b) Thickness of stiffener (Vertical plate) is from 8mm to 20mm;
c) Width of end plate (Horizontal plate) is in the range of 100mm to 500mm;
d) Thickness of end plate (Horizontal plate) is from 10mm to 40mm;
 

2. T Beam Fabrication Machine for Steel Structure Use:

1) Welding Mode in Steel Structure Purpose T Beam Welding Machine:

In Steel Structure plant, just like H Beam Production Line, the finished welding operation on T Beam is SAW (Submerged arc welding. It can be:
a) Either customer cut a piece of finished H Beam in half, into 2 pieces of T Beam;
b) Or single time of welding operation from one piece of flange and web, into T Beam (For producing welding H Beam, welding operation need to be implemented 2 times);
2) There is no need of edge rounding in process route of steel structure use T Beam production;

3) Workpiece Specifications of Steel Structure Use T Beam Production Line:

Steel structure application T Beam has larger dimension than those for Shipbuilding:
a) T Beam stiffener (Vertical plate) height is usually in the range of 200mm to 1500mm,
b) T Beam stiffener (Vertical plate) thickness is from 6mm to 32mm;
c) T Beam end plate (Horizontal plate) width is in the range of 200mm to 800mm;
d) T Beam end plate (Horizontal plate) thickness 8mm to 40mm;

4) Application of Steel Structure Use T Beam Production Line:

There is seldom sole purpose machine line group on T Beam production in Steel Structure plant. Usually it is in the form of H Beam Production Line and H Beam Fabrication Machine, which can produce both T Beam and H Beam, sometimes even BOX Beam. For example, LHT model H Beam SAW Welding Machine can weld on BOX Beam H Beam T Beam with single set of equipment.

In practice, there are two general ways of T Beam manufacture adopted by customers, either in the way of machine group of T Beam Production Line, or individual equipment of 3 in 1 T Beam Fabrication Machine:

A. Welding T Beam Production Line:

1. This is traditional way of welding T Beam production, and still take fairly large share nowadays. It is in majority used in large scale Shipbuilding facility, for producing T Beam in batch with large volume;

2. A complete line on T Beam Production is composed of below major machines:

1) CNC Strip Plate Cutting Machine;
2) Edge Rounding Machine;
3) Multi-head T Beam Assembly Machine;
4) Multi-head T Beam Welding Machine;
3. Characteristic of such machine line on T Beam production lies at its output: There are usually 5- 6 pieces of T Beam to be produced at the same time.
 

B. Three in One T Beam Fabrication Machine:

1. This equipment is similar to 3 in 1 H Beam Fabrication Machine (H Beam Assembly Welding Straightening), which is widely applied in Steel Structure Industry;
2. Integrating three functions of T Beam assembly, welding and straightening, three in one T Beam Fabrication Machine has advantages of compact size, high efficiency and budget saving;
3. This machine is usually installed in working sites with medium level volume of T Beam. It manufactures one piece of T Beam at any moment.

1) Technical Brief on CNC Flame Cutting Machine:

a) CNC Strip Cutting Machine cuts out carbon steel plate by means of Oxygen fuel and cutting gas, usually Propane, sometimes Acetylene;

b) The machine has 1 or 2 pieces of CNC control cutting torch at front side of machine gantry frame, for fulfilling profile cutting; And 6 to 8 pieces of strip cutting torch at rear side of gantry frame, for cutting out several pieces of narrow plates with varied width;
c) The CNC control cutting torches have capacitance type height controller, to counteract negative influence from uneven steel plate; The strip cutting torches have manual adjust height controller.
