LBA10 Automatic T Beam Welding Machine for Shipbuilding

Quantity:

The LBA10 Automatic T Beam Welding machine performs the 4th step of welding T Beam production next to assembly and tack welding.

 

    1. Outline on LBA10 Automatic T Beam Welding machine for Shipbuilding:

    1.1  Comparison with H Beam Welding machine:

    1) This T Beam Welding Machine is the counterpart of H Beam welding in welding H Beam production, which 

       implements the similar function of workpiece welding following assembling;

    2) However, there exist three obvious differences between T Beam Welding Equipment and H Beam

       Welding:

     a) The T Beam Welding machine for shipyard adopts with Gas shielded CO2 welding, instead of SAW 

      (Submerged arc welding) in H Beam welding. This is because T Beam is usually used in Shipbuilding industry, 

      which poses higher demand on toughness of welding seam;

     b) Compared with SAW, the GMAW CO2 welding process generates large volume of fume and arc light. So, 

       workshop of such automatic T Beam Welding Equipment need to have welding fume extracting and cleaning 

      system put into use, or the machine itself is equipped with such welding fume recycling unit, which is shown in

       the attached picture;

     c) Please check attached picture. The H Beam welding can only weld 1 (LHC) or 2 (LHA/ LHT) pieces of H Beam

        one time, while this T Beam Welding Equipment for shipyard can weld several (5 or 6) pieces of T Beam at the 

       same time, which boosts productivity greatly;

    1.2  Structure and Configuration:

     1) As can be seen from the attached picture, with as much as 5~6 welding stations installed on its gantry frame

       body, this automatic T Beam Welding equipment for shipbuilding is a set of “giant” machine;

     2) The gantry frame body itself also serves as operating and maintenance platform of the machine, with 

       working station fit onto it. During working, operator stands on this working station to manage and monitor 

       welding process of the T Beams;

     3) All the welding power supplies are put on the overhead platform. So, the gantry frame takes majority of 

        loading weight of this T Beam Welding equipment for shipbuilding, which should be strong, firm, and sturdy;

     4) Control board of the machine is installed at lateral side of the gantry frame, with operating pendant installed

       at the front side of the gantry adjacent to working station. In this way, both plain & simple cable routing, as 

       well as convenient operation are considered together;

    1.3  Operation:

     1) Operation of this T Beam Welding machine is similar to that of H Beam welding machine. During work, the 

       workpieces of T Beam are put onto its rack and kept standstill, while the gantry frame of the machine travels 

      along its rail in welding speed, welding the T Beam workpieces simultaneously;

     2) Due to the potential harm caused from welding fume and arc light generated from CO2 welding, operator of

       this automatic T Beam Welding equipment should put on proper PPE (Personal Protective Equipment), 

       including Welding helmet and goggles, and abide by security regulation of the facility.
