As a technology based company, Wuxi JACK concentrates on exploring technical knowhow in our product, to get the best performance of product. For I H Beam Gantry SAW Welding Machine, one of the critical control points is welding seam tracing mechanism, which determines submerged arc welding quality of the I H Beam Welding Machine directly.

1) Design sketch on LHC and LHT models I H Beam Welding Machine: (Fig.1,2)

5) 2 types of LHT I H Beam Gantry SAW Welding Machine: (Fig.3,4,5)

1. Application of LHC Column Boom I H Beam Welding Machine:

1) Using Site: LHC is the specialized I H Beam Welding Machine, specifically applied in fully automatic H Beam Production Line;

2) One Model Fitting for All: Same as LHT, there is only one model LHC I H Beam Welding Machine: All web heights of T/ I/ H Beams can be welded in this open mechanical structure I H Beam Welding Machine.
 

2. 4 Unique Points of LHC Column Trolley Open Structure I H Beam Welding Machine:

Compared with LHA closed frame and LHT T frame I H Beam Gantry SAW Welding Machine:
1) No workpiece racks necessary for LHC I H Beam Welding Machine. Instead, T/ I/ H Beams are put onto 60° Overturning Rack of the H Beam Production Line, as you check from the left hand photo;
2) Only 1 piece of SAW welding torch installed in one set of LHC I H Beam Welding Machine. So, only piece of H Beam can be welded in LHC at any moment;
3) 4 Sets as a Group: The on site application of LHC I H Beam Welding Machine in automatic H Beam Production Line involves 4 sets of LHC working as a group. This is for completing H Beam 4 welding seams fabrication, with its one time flow through H Beam Production Line, without turning around;
4) Material Handling in LHC model I H Beam Welding Machine is safe and labor saving: Flipping and conveying workpiece is realized with 60° Overturning Rack and Steel Conveyor.
 

3. Technical Parameters of LHC Column Open Structure I H Beam Welding Machine:

1. Technical Features of LHT Open T Structure I H Beam Gantry SAW Welding Machine:

LHT is the intermediate equipment between LHC column boom and LHA gantry moving I H Beam Welding Machine, common points with LHC and LHA both:
1) Mechanical main body of LHT I H Beam Welding Machine has T shape structure. The 2 pieces of H Beams are laid at external sides of T frame during SAW. So, it has open structure;
2) Welding torch quantity: In one set of LHT I H Beam Gantry Welding Machine, there are 2 pieces of welding torch. So, 2 pieces of T/ I/ H Beams can be welded simultaneously in the LHT machine;
3) Application Site: LHT I H Beam Gantry SAW Welding Machine works in semi-automatic H Beam Production Line;
4) Material handling in LHT, including overturning and transporting of workpieces, are also toilful, which needs special attention for operator safety and workpiece protection;
5) One Model for All Sizes Workpieces: LHT I H Beam Gantry Welding Machine has open style mechanical main body of T Frame, no restriction on workpiece size.
 

2. Uniqueness of LHT I H Beam Gantry SAW Welding Machine:

1) One machine with triple use: Benefitting from its mechanical T frame structure, applicable workpieces for LHT I H Beam Welding Machine is not confined to T /I/ H Beam;
2) BOX / Cross Beams are also available for being fabricated in the LHT.
