A. Basic Role and Importance of BOX I H Beam Welding Machine:

1. Function of BOX I H Beam Gantry SAW Welding Machine:

B. Other Types of Applicable Workpieces in Steel Structure BOX I H Beam Gantry SAW Welding Machine:

1. Operation Feature of LHAZ Series I H Beam SAW Welding Machine:

1) Application: Applied in semi-automatic or manual H Beam Production Line; Or work as single set welding machinery;
2) Shown in the lefthand photo, operating pendant and SAW control consoles are installed at middle point of main frame horizontal beam, this is basic difference with respect to LHAC models lateral operating type;
3) Operator Position: So, during work, operator stands at middle isle between the 2 arrays of workpiece racks, beneath motor drive moving gantry frame of the machine.
 

2. Advantages and Disadvantages of LHAZ Middle Operating Gantry Frame H Beam Welding Machine:

1) Advantage: Reduce Number of Operator: 1 operator is sufficient for operating and monitoring on working process on the 2 pieces of H Beam simultaneously. Labor saving, reduces variable cost;
2) Disadvantages:
a) Operator labor intensity is more intensive than operators of LHAC models;
b) Wider Land Space Involved: For the same of H Beam web max. height, LHAZ takes 10% wider workshop area than LHAC models.
 

3. Operation on LHAZ Model I H Beam Gantry SAW Welding Machine:

1) Welding Efficiency: There are 2 sets of welding torch in one set of LHAZ. So, the machine can fulfil SAW welding on two pieces of H Beam simultaneously;
2) H Beam Flipping: With the help of traveling crane or other tool, every piece of H Beam needs to have 4 times 90° flipping, to complete 4 passes of welding seam. This poses certain challenge on operator safety/ working pace, and workpiece protection;
3) Welding Technique: Single Arc/ Twin Arc/ Taden Arc submerged arc welding.
 

4. Technical Parameters of LHAZ Center Operating I H Beam Gantry SAW Welding Machine:

1. Operation Feature of LHAC H Beam Welding Machine:

1) Application: Used in semi-automatic or manual H Beam Production Line;
2) 2 sets of operating pendants are installed at both ends of mechanical main frame respectively;
3) Operator Position: During work, operators stand at both sides external of H Beams supporting rack, 1 people at 1 side respectively, beneath and inside the motorized moving mechanical frame;
4) 2 Arrays of H Beam Holding Racks: Correspondingly, H Beam orientation is also different from LHAZ middle operating.
 

2. Technical Features of LHAC Models Gantry SAW I H Beam Welding Machine:

1) Welding Efficiency: 2 groups of welding torch units in 1 set of machine, welding on 2 pieces of H Beam together;
2) Number of Operator: Two, 1 people takes care on 1 piece of H Beam welding operation respectively;
3) Technical Features of LHAC side managing I H Beam SAW Welding Machine are same as LHAZ center managing: Welding technique (Large current SAW)/ Productivity (2 pieces simultaneously)/ H Beam handling;
4) Electric Control: There is interlock in machine electric control system, so that 2 operators operation in pace can be 100% guaranteed; No wrong operation happened.
 

3. Strong and Weak Points of LHAC Lateral Operating I H Beam Welding Machine:

1) Positive 1: Compacter overall dimension than LHAZ models: Occupy less workshop area;
2) Positive 2: Less stressful workload than LHAZ models: One operator monitors on SAW welding operation of one H Beam only, compared with two pieces in LHAZ center control;
3) Weak Point: Double variable cost compared with LHAZ center management.
 

4. 2 Standard Models of LHAC Lateral Management Gantry Moving I H Beam SAW Welding Machine:

1) LHA4C: For welding on BOX/T/I/H Beam with max. web height 1500mm. This is the model with the biggest sell volume, developed for HB1500 H Beam Production Line;
2) LHA5C: For welding on BOX/T/I/H Beam with max. web height 2000mm, developed for heavy duty HB1800/HB2000 H Beam Production Line.

5. Technical Parameters of LHAC Lateral Management I H Beam Welding Machine:

1. Working Scope of LHG/LHD Series Steel Structure and I H Beam SAW Welding Machine:

1) Tailor Made: This series belongs to special purpose machinery, one design for one business case. Unlike conventional LHA/ LHC/ LHT series, one design being applicable for numerous cases;
2) Flexible Wide Variety Workpieces: Varied design and specifications, to meet on niche demand from small lab use, to large lamp post.
 

2. Technical Features of LHG/LHD Gantry Frame Steel Structure and H Beam Welding Machine:

1) Overall Dimension: Broad range of overall size, from 1600mm height, fitting for adult people operation level; To 4000mm height welding torch installation, need lateral ladder for access;
2) Welding Torch Degrees of Freedom in Steel Pipe BOX H Beam Gantry SAW Welding Machine:
To fulfil welding on complicated working parts, such as tapered member, welding torch should be able to being managed in directions of:
a) X Axis: Moving leftward and rightward along horizontal front beam machine mechanical main frame;
b) Y Axis: Moving forward and backward along the entire length of long workpieces, by means of box frame main body driven along 15-20m length parallel rails;
c) Z Axis: Being driven ascending up and descending down.
