LHA5Z Center Control Gantry Type H Beam Submerged Arc Welding Machine

Quantity:

Among the 3 types of automatic H Beam welding machine, the gantry type LHA is the only one has many variations in terms of operator station (center control LHAZ versus side control LHAC), and rail span(4/5/55). This is determined by feature of its machine frame structure: Gantry is a kind of closed one, which poses restriction on both H Beam size and operating station. Instead, both column type (LHC) and T type (LHT) high efficiency H Beam Submerged Arc Welding machine has open type machine body, which has no such limit.

 

Of which the LHA5Z is the most often selected model of automatic gantry type H Beam welding machine. This is because:

  1) It can weld H Beam with web up to 1800mm, meeting majority H Beam production demand;

  2) It need only one operator to take care the SAW process



Of course, every solution has its advantage and disadvantage. For center control gantry type H Beam welding machine, 2 obvious shortcomings are:

  1) As explained, the same rail span of LHAZ has smaller H Beam size than side control LHAC. With this 5m rail span, with LHA5C automated gantry type H Beam welding machine, the biggest H Beam web width can be up to 2000mm, compared with 1800mm for LHA5Z;

  2) Another is operation inconvenience for operator. As can be conceived, for side control of LHAC, operator stands at outside of H Beam, which is easy for operator to move around for various action, such as fetching a tool, checking and confirming a condition, etc.; While for operator of LHAZ H Beam gantry welding machine, standing in the middle of the machine beneath the gantry and between the 2 rails, he or she needs to make a detour in further distance to accomplish the tasks.

 

Taking LHA5Z as example, this is the complete configuration for a set of high efficiency gantry type H Beam welding machine:

  1) Machine body--- Gantry frame, 2 sets of travel carriage for fitting welding torch, wire-feeding tube and attachments;

  2) Rail --- For gantry travel along H Beam and perform SAW

  3) Mechanical welding unit --- 2 sets of welding torch and its attachment;

  4) SAW Welding Power Supply --- 2 sets, either Chinese brand HuaYuan(ZD7-1000) or U.S. Lincoln(DC-1000) has stable and solid quality;

  5) Wire feeder --- 2 sets, for feeding welding wire;

  6) Flux Recovery unit --- 2 sets, for welding flux recycling;

  7) Arc Tracing unit --- 2 sets, for welding arc guide and torch adjustment;

  8) Control System---Control board, operating panel, control elements;

  9) Piping System--- Power supply cable of welding machine, control cable, air source tube, control cable of gantry, wire-hanging sliding rack, welding cable, etc.

  10) Spare parts --- 3 push-buttons, 3 pieces of 6A、4A RL8B-32fuse each, 2 pieces of 10A fuse (Spare parts may varies on specific model and customer demand)
