Shipbuilding Purpose TB Series Welding T Beam Production Line

A. Application of Shipbuilding Use T Beam Production Line:

1. Applied Industry: Shipbuilding facilities is the most important and representative application sites of welding T Beam Production Line. The technical features of delivered welding T Beam are properties what distinguish T Beam from other steel structure members: BOX Beam from BOX Beam Production Line, and H Beam from H Beam Production Line;

2. The Unique Characteristics of Shipbuilding Use Welding T Beam Production Line:

This mainly lie in:

1) T Beam end plate painting adhesion property: By means of edge rounding and trimming;

2) Impact value of finished welding seam: With high IK (Impact resistance performance) value CO₂ GMAW welding;

3) Overall dimensions of finished T Beam:

Generally smaller than H Beam, in the dimension range of:

a) 300mm ~ 1000mm height, compared with 200mm ~ 1500/ 1800/ 2000mm height in H Beam;

b) 100mm ~ 500mm width, compare with 150~ 800 width of H Beam;

c) 3 ~ 20mm stiffener thickness, compared with 6~ 32mm in H Beam web.

 

B. Exclusive Characteristics of Shipbuilding Use T Beam Production Equipment:

There are certain unique features with manufacturing process of shipbuilding use T Beam, which are mainly embodied in below four aspects:

1. End Plate Edge Trimming and Rounding Step: (Fig.1)

a) Why Need: This is because in Shipbuilding facilities, painting adhesion is a very important factor taken for parts and assemblies, for the purpose of maintaining long term qualified painting quality, working under surroundings of high moisture, or water;

b) RH800/ RH1000 narrow plate Edge Rounding Machine is for deburring and rounding edge of T Beam end plate, trimming its edge from sharp angle into round angle of R2.5mm, thus bringing along below benefits of:

1) Improve on painting adhesion, promising much better painting quality and protect it from corrosion from water or moisture;

2) Eliminate risk of cut/ incise from sharp edge of workpiece;

3) Remove stress concentration, giving better raw materials of plate for next step of assembly;

4) Much better appearance of finished product;

2. Continuous GMAW CO₂ welding in T Beam Welding Machine:

Wuxi JACK LBA10 model machine performs on batch T Beam stiffener welding: (Fig.2)

1) Welding Technique: In TB series shipbuilding use T Beam Production line, to get higher welding seam impact value of finished welding T Beam, 500A medium current continuous GMAW CO₂ welding takes the place of H Beam production 1000A large current SAW (Submerged Arc Welding);

2) High Productivity: One set of LBA10 T Beam Welding Machine usually has several (up to 5~ 6) pieces of welding torch and motor drive moving carriages, simultaneously producing 5~ 6 pieces of finished T Beam, compared with 1~ 2 pieces in single set of H Beam Welding Machine, or 4 pieces in H Beam Production Line;

3. Environment Protection Mechanisms in T Beam Fabrication Machine:

1) Why Need: Due to the heavy welding fumes and arc light generated in the process of T Beam CO₂ welding, EHS (Environment Health Safety) is the foremost factor to be considered at the working site of T Beam Welding Machine;

2) This is usually accomplished with measures of:

a) Equipment: At T Beam CO₂ welding site, installing and put into use welding fume extract and cleaning system, of negative pressure;

b) Operator Protection: Although with automatic welding, operator should put on PPE (Personal protection equipment), including welding helmet and goggle;

4. The above listed technical features apply to integrated function 3 in 1 T Beam Fabrication Machine.

C. Process Technology and Corresponding T Beam Production Equipment：

1. End Plate and Stiffener Plate Cut:  

1) CNC Strip Plate Cutting Machine--- This is a kind of universal 1^st operation machine, not confined to welding T Beam production site:

2) Wuxi JACK CNC-CG4000 model CNC Flame Cutting Machine: (Fig.3)

2. End plate Deburring and Rounding:  

1) The attached 2^nd photo and below: This is realized with RH800/ RH1000 Edge Rounding Machine, as shown in the attached:

5. Stiffener Straightening (Optional): T Beam Straightening machine (Optional);

6. Single Equipment of T Beam Fabrication Machine:

Feature: This is a highly efficient equipment on small T Beam production. It incorporates 3 steps in T Beam (Assembly/ Welding/ Straightening), and is usually applied under the conditions of:

1) Customer has limited budget on purchasing T Beam Production Equipment;

2) Customer site has limited land scape to deploy machines on T Beam production;

3) Customer only produces small light duty T Beam;
