1) From the name of this product section, we get to know the specialty of workpieces delivered with PHJ series Welding H Beam Fabrication Machine:
2) Both symmetric and asymmetric cross section welding H Beam;
3) Please check attached the 6th picture on compare between PHJ and ZHJ Vertical H Beam Welder (3 in 1 H Beam Welding Machine).
1)“Symmetric” and “Asymmetric” refers to assembling of two flanges and one web in H Beam, that the two joints between web and each of the flange is/ is not at the middle point of flange:
a) In practical use, majority welding H Beam has symmetric cross section, which account for over 70%~ 80%, depending on specific countries/ regions/ projects);
b) This is the reason we developing on ZHJ series integrated function H Beam Welding Machine, on the basis of PHJ series H T Beam Welding Equipment;
c) Especially nowadays in China, ZHJ series Fit Up Full H Beam Fabrication Machine has taken more and more market share;
2. This is also the main distinction between PHJ series and ZHJ series H Beam Fabrication Machine, from perspective of customer, or application. That ZHJ series Vertical H Beam Welder can only produce symmetric welding H Beam and T Beam, while PHJ series Vertical H Beam Welder can produce both symmetric and asymmetric ones;
From operator and designer point of view, the distinction between PHJ series and ZHJ series H Beam Fabrication Machine is its alignment way of flange and web:
1) This is the reason why PHJ series 3 in 1 H Beam Welding Machine (3 in 1 T Beam Welding Equipment) has capability on delivering asymmetric workpiece:
2) The final assembling (Precise alignment) of flanges and web are all adopted with the working manner of one side hydraulic driving, the opposing side manual handwheel;
3) As shown in attached the 2nd and 3rd photos. The photos clearly demonstrate on the handwheels for turning alignment rollers of flanges and web respectively in the Vertical H Beam Welder. (The two handwheels are deployed at both sides of the H Beam Assembly Welding Straightening Integral Machine). As can be seen from the 2 photos, to save effort in the process of turning, each of the handwheels are equipped with 2 sets of hand reducers;
4) The handwheels for turning on alignment rollers of flange and oil cylinders for driving alignment rollers of web are installed in stagger at both sides of the Welding H Beam Fabrication Machine.
1. The 4th attached picture records the moment of welding T Beam produced in PHJ Series H Beam Welding Machine. It is WIP (Working in process) for making welding H Beam, also the final product of welding T Beam;
2. In this sense, the 3 in 1 H Beam Fabrication Machine is also a set of Vertical H Beam Welder (3 in 1 T Beam Welding Equipment), with two folds productivity compared with manufacturing welding H Beam (Only one round of pulling through operation is necessary in the Vertical H Beam Welder , compared with two rounds in making welding H Beam);
3) As can be seen from the picture, the main pressing roller has concave rim with a circle of slot around its middle line. This is for mating perfecting with web during process of T Beam welding in the H Beam Welding Machine (T Beam Welding Equipment).
