1. Conventional The Largest Model: PHJ20 is the largest model of standard PHJ series 3 in 1 Welding H Beam Fabrication Machine;
This model of Pull Through H Beam Welder can deliver welding H Beam in the specfications of:
1) The max. H Beam web height is 2000mm;
2) H Beam flange size (Width and thickness) / web thickness is same as PHJ15 and PHJ18;
3) Cross section of H Beam in symmetric and or asymmetric flange position with respect to web. (see attached picture):
1) This is the cornerstone, or working unit of PHJ series Automatic H Beam Production Machine;
2) It is in the structure of gantry base frame, and consisted of:
1) This unit is assembled into inversed U shape with welding structure members:
2) Assembling Precision Management: For acquiring precise assembling of this PHJ20 model 3 in 1 Automatic Integrated H Beam Welding Machine, the positioning of its structure members is made with a set of positioning pin hole fixture;
3) Forming Main Body of the Pull Through H Beam Welder: This unit helps to come into being the complete mechanical main body of PHJ20 Welding H Beam Fabrication Machine, with the hydraulic drive downward stroke holding unit fit at its top middle:
1) Assembling Position: This is the lower section of the Pull Through H Beam Welder main body;
2) Important Role: Base bed also serves as “working station” of PHJ20 model Welding Automatic Integrated H Beam Welding Machine: That all the critical units of Assembly / Welding and Straightening units are all installed onto the base bed:
3) Accordingly, all the core operation of H Beam Assembly/ Welding/Straightening is performed at central working zone installed onto the base bed;
4) Drive and transmission units of PHJ20 model 3 in 1 H Beam Welding Machine is also installed at its bottom;
As introduced in the product section of PHJ18 model 3 in 1 Welding H Beam Fabrication Machine, Assembling unit is consists of:
a) 6 sets (Or, 12 pieces) of web alignment rollers alongside left and right of H Beam web;
b) 2 sets (Or, 4 pieces) of web alignment rollers on top of flange;
2) The other nomination: In Pull Through H Beam Welder, this assembling unit has the alternative name of Self-Alignment unit;
a) These alignment rollers installed in pair carry out the first task of PHJ20 model Pull Through Beam Welder:
b) To fulfil precise positioning and secureness of H Beam flanges and web, preceding the next step of SAW/ CO2 welding;
4) Drive Form: Working motion of assembling alignment rollers is hydraulic oil cylinder drive.
1) As introduced in the product section of PHJ18 model 3 in 1 Welding H Beam Fabrication Machine, there are two options of SAW and or CO2 welding;
a) SAW (Submerged arc welding) is for producing medium duty welding T/ H Beam, with web and flange thickness up to 40mm:
b) CO2 GMAW is for fabrication light duty small welding T/ H Beams, with web and flange thicknes usually in the range of 3mm to 12mm:
There are several brands of welding power supply available for either of the welding mode:
1) Chinese mainland produced HUAYUAN brand for both SAW and GMAW;
2) American LINCOLN for SAW;
3) Japan Panasonic for CO2 GMAW;
1) Whatever the brands of welding power supply, it is equipped with wire feeding unit and control console in the PHJ series Automatic H Beam Production Machine;
1) Besides the basic 2 sets of welding torch and power supply, for official running of SAW Welding H Beam Fabrication Machine, welding flux unit is a necessity;
2) Installation: It is fit on the upper section of mechanical gantry of PHJ series Automatic H Beam Production Machine (See attached picture) and below:
