Steel Structure Welding H Beam Three in One Fabrication Machine

A. The Finished Product of PHJ and ZHJ series Integral Function H Beam Assembly Welding Straightening 3 in 1 Machine:

1. In Steel Structure Industry, there are 2 kinds of H Beam: Hot rolled and welding type;

2. The welding H Beam has larger dimensions and broader application than hot roller H Beam. Correspondingly, Steel Structure H Beam Machine has very extensive use in Steel Structure facilities worldwide: It is necessary equipment at every plant;

3. Taking the position of traditional H Beam Production Line for producing light to medium duty welding H Beam, the PHJ and ZHJ series H Beam Assembly Welding Straightening 3 in 1 Machine is for automatically producing welding H Beam in various sizes, with the strong points of: High quality, high productivity and low cost;

2) Welding H Beam produced from Wuxi JACK 3 in 1 Function Steel Structure H Beam Machine: (Fig.2)

B. Benefits of PHJ and ZHJ Series Integral Function H Beam 3 in 1 Fabrication Machine:

1. The 3 General Steps: To manufacture finished H Beam from steel strip plates, the raw materials need to go through 3 general steps of: Assembly, Welding and Straightening. The traditional H Beam Production Line has 3 types of equipment for completing these 3 steps;

2. From 3 Machine to 1: Comparatively, the PHJ and ZHJ model H Beam 3 in 1 Fabrication Machine integrates the 3 functions into one equipment, which provides huge profit for Steel Structure customers on saving investment and raising productivity. This is the reason that, why this new generation Steel Structure H Beam Machine is also named as 3 in 1 Vertical H Beam Welder, or 3 in 1 H Beam Welding Machine;

3. Remove Transferring Equipment: Besides, in traditional H Beam Production Line, there should be internal logistics unit among the 3 machines for WIP (Work in process) flipping and transfer. Now, with the use of Integral Function H Beam 3 in 1 Fabrication Machine, the traditional H Beam Production Line is “Concentrated” into an individual equipment of 3 in 1 H Beam Welding Machine.

C. Process Technology of PHJ and ZHJ Series 3 in 1 Function Steel Structure H Beam Machine:

Below is the typical process routed realized inside this 3 in 1 H Beam Welding Machine:

1. Assembling: From Raw Material Plates to Flange and Web in 3 in 1 Vertical H Beam Welder:

1) 2 piece of long narrow steel plates which are served as flange and web of H Beam are sent to H Beam 3 in 1 Fabrication Machine;

2) The Assembly unit is deployed at input conveyor and incoming side of central working area, in H Beam Assembly Welding Straightening 3 in 1 Machine;

3) The assembling is performed with 2 steps: The first step for rough positioning and clamping of the web and flange is completed with three sets of pulling rod system arranged alongside the input conveyor:

2. H Beam CO₂ or SAW Welding in the PHJ and ZHJ 3 in 1 H Beam Welding Machine:

There are 2 types of welding mode in 3 in 1 Function Steel Structure H Beam Machine:

1) Most majority is in SAW- Submerged arc welding, which accounts for over 90% of practical use, for welding small to medium duty H Beam;

2) Minority condition of the 3 in 1 H Beam Welding Machine utilizes GMAW CO₂ welding, which sees its application less than 10%, for producing welding H Beam with web thickness around 6~ 10mm;

3) Sometimes, to have full utilization of the H Beam 3 in 1 Fabrication Machine, even the models adopting GMAW CO₂ welding is equipped with SAW power supply;

4) In PHJ and ZHJ series 3 in 1 Function Steel Structure H Beam Machine, welding is implemented with 2 sets of power supply, together with 2 sets of welding system: The welding torch, wire feeder, control panel and flux recovery unit:

3. Flange Straightening in PHJ and ZHJ 3 in 1 Function Steel Structure H Beam Machine:

1) H Beam Flange usually generate deformation after welding caused of heat input effect;

2) The PHJ and ZHJ series H Beam 3 in 1 Fabrication Machine has its straightening unit deployed at outlet side of central zone, to make the flange straightened;

3) Flange straightening operation is done with hydraulic drive. The critical elements are 3 pieces of heavy force solid type straightening rollers, the top larger one with downward stroke working mode;
