LHA5C Side Control Gantry Type H Beam Submerged Arc Welding Machine

Quantity:

LHA5C side control H Beam gantry welding equipment produces H Beam with web size of up to 2000mm, which is the largest type same as LHA55Z in center control. In this respect, it can be called as Large Gantry type H Beam Submerged Arc Welding Machine officially as its full name.

As review, for gantry sketch of side control, please check attached illustration.

 

Summary introduction on Automatic H Beam Gantry Welding Equipment including LHA5C:

  1) Outline:

   This automated H Beam gantry welding equipment is for automatic SAW of H Beam.

   -  After assembled and spot welded with Assembly and Tack Welding machine, the H Beam is put on the 

      supporting racks of this large H Beam submerged arc welding machine, in the flat position of 45° fillet weld. 

     (The supporting racks are put and fixed on the workshop floor beneath the gantry);

   -  The 2 carriages fit with 2 sets of SAW welding torch can move leftward and rightward along transverse beam

     of gantry, and up and down along the 2 arms installed on the transverse beam of gantry. In this way, the 2 

     welding torches can move along 3-axis of X/Y/Z, making its tip aiming at welding seams all along (the forward

     and backward movement of welding torches in horizontal plane is realized with gantry travel along the rails);

    - There are 2 sets of automatic welding seam tracing unit at front end of the 2 carriages (one tracing unit in one

       carriage each);

    - Gantry moves along rails, performing automatic SAW welding on the 2 pieces of H Beam;

    - This series of efficient H Beam gantry welding equipment is also equipped with automatic Flux Deposition and

      Recovery unit;

  2) Major components:

As introduced in previous product, this high precision H Beam gantry welding equipment is mainly composed of gantry, carriages, welding torch mechanical tracker, welding machine, flux recovery and recycling unit, gas system and electric control system;

  3) Transmission of Welding units

  - By means of sets of adjustable eccentric roller and high precision V-section rail, vertical and horizontal smooth

     travel of welding torches can be guaranteed;

  - The horizontal movement of carriages is controlled with handle reducer and gear-rack unit;

  - Vertical motion of welding torch is fulfilled with motor reducer and gear-rack;   

  4) SAW process controlled with Arc Tracing unit:

    The 2 sets of arc tracing unit serve as feedback of welding process, sending signal to control system of this high

    quality H Beam gantry welding equipment, and thus 2 sets of welding power supply accordingly. To be specific,

     it monitors welding process of SAW, and sends back detecting signal to control center, forming a closed-loop

     negative feedback control system of SAW process.

    These 2 sets of arc tracing unit are designed and made by us (Wuxi JACK), and installed on the welding 

    carriages on the transverse beam of the gantry.
