PHJ20 Integral Function H Beam Welding Machine of Fit Up Full

Physical Characteristic of PHJ20 Model Integral function H Beam Welding Machine:

As can be found from the attached 1^st photo, PHJ20 model 3 in 1 T Beam welding Machine, is the tallest model in PHJ series H Beam Fabrication Machine. It has total height of 5.1m mechanical main frame.

1. What can PHJ20 Model 3 in 1 H Beam Welding Machine do for Customer?

1) Straightening Unit: The attached 1^st photo shows a set of Wuxi JACK PHJ20 H Beam Assembly Welding Straightening Machine be in production at Russian customer workshop. The front side of the machine main frame is its straightening unit;

2) Specification: PHJ20 model integral function 3 in 1 H Beam Welding Machine has downward compatibility with PHJ15 and PHJ18 smaller models, that it can produce all the workpieces of PHJ15 and PHJ18, but not vice versa: The distinct workpiece that can be produced from PHJ20 Fit Up Full H Beam Fabrication Machine is welded H Beam and T Beam of asymmetric cross section, in the web height of 2000 mm;

3) Producing T Beam and H Beam with one machine: PHJ series 3 in 1 H Beam Welding Machine can also be applied as Automatic T Beam welding Machine, with half the cycle time for producing T Beam as producing H Beam:

4) Major Difference Between 3 in 1 H Beam Assembly Welding Straightening Machine and Traditional H Beam Production Line:

 When judging steel structure members H Beam, the difference and connection between “heavy duty” and “large size”, as well as when to choose H Beam Production Line, when to select PHJ series 3 in 1 H Beam Assembly Welding Straightening Machine, is the flange thickness and related welding seam toe to be produced:

a) Heavy duty H Beam: When producing welded H Beam with flange thickness above 40mm, and corresponding SAW seam should have welding seam toe bigger than 8mm, which involves more than single time of submerged arc welding, the traditional H Beam Production Line;

b) Light and Medium Duty H Beam: If customer produces welded T Beam/ H Beam with welding toe size of 8mm and or less, which single pass of submerged arc welding is sufficient, then PHJ and ZHJ series 3 in 1 Integral function H Beam Welding Machine can deliver the ideal outcome for customers, in terms of both financial, productivity, and quality;

5) The Cost Saving for Customer with Integral function H Beam Welding Machine: 

In a word, in the field of small to medium size welded T Beam H Beam production, one set of PHJ20 model 3 in 1 H Beam Welding Machine equals to: 

a) One set of Z20 H Beam Assembly and Tack Welding Machine;

b) One set of LHA5Z H Beam Submerged Arc Welding Machine; 

c) One set of YTJ50 H Beam Straightening Machine;

d) Logistics unit, such as traveling crane, steel cart;

6) Just take a look on PHJ20 model machine, it has very atmospheric appearance and reasonable structure.

2. Technical Details of PHJ series SAW H Beam Fabrication Machine:

1) High quality welding: The attached 2^nd picture shows submerged arc welding process in this 3 in 1 H Beam Welding Machine. It is the core and essential operation of the machine. To get the optimum welding quality, and protect the welding torch from being bumped, the welding torches have two levels of position adjusting system: 

a) The first is by means of the D.C. motor drive 45° oblique bracket,  to adjust on welding torch position;  

b) The second is by means of hand driven fine tuning on cross slides in both horizonal and vertical direction;

2) Wuxi JACK leading position: With years of accumulation, Wuxi JACK has fully considerate on not only the general structure and principle, but also operation details of the Welding H Beam Fabrication Machine. Please check the attached 3^rd picture as example. It is taken at the assembling alignment roller and welding earthing bolt section. Right behind the assembling roller, there is a small hydraulic jacking unit,

3) This unit has two functions for guaranteeing on high standard running of the Integral function H Beam Welding Machine:

a) First, for flanges and web of long length and small thickness (5~6mm), when sent into the H Beam Fabrication Machine, it is easy to droop down due to insufficient rigidity. By this time, this hydraulic mechanism will rise up, supporting the drooped workpiece;

b) Second, the lateral side of this mechanism can be used for alignment of flange and web during its feeding into the Integral function H Beam Welding Machine.
