LHA Gantry Type H Beam Submerged Arc Welding Machine

Quantity:

As introduced in product category of automatic H Beam Submerged Arc Welding Machine, it is the 2nd set of core H Beam production equipment, and also the most important one. It determines quality of produced welding H Beam to the greatest extent.

 

This series of H Beam welding machine performs 45° fillet position submerged arc welding (short for SAW) on the assembled and tack-welded H Beam made with assembly machine. For each piece of H Beam, there are 4 seams to be welded, see below sketch:

 H Beam-1

Also, as introduced, depending on variety in structure of machine frame, the H Beam welding machine has 3 general types of:

1)  Gantry type H Beam Submerged Arc Welding Machine

2)  Column type

3)  T type

 

Of which the gantry type sees the widest application. It can only be used in semi-automatic H Beam production line, or work as individual automatic H Beam gantry welding machine. Due to feature of its frame structure, it can not be applied in automatic line.

 

Each set of automated H Beam gantry welding machine has 2 welding stations installed on its gantry frame. And, based on position of operator, this gantry H Beam submerged arc welding machine has 2 sub categories of center control (LHAZ) and side control (LHAC). Please check below sketches to compare:

Center control (LHAZ) high efficiency H Beam gantry welding machine:

 2- LHAZ


Side control (LHAC) efficient H Beam gantry welding machine:

 LHAC

We can see the LHAZ need only one operator to take care SAW process, while LHAC need two operators. On the other hand, for welding H Beam of same size, the LHAZ has larger size of gantry compared with that of LHAC. So, each type of these high quality H Beam gantry welding machine has its advantage and disadvantage.
