1) Business Background: 3 in 1 H Beam Fabrication Machine has been put into market by Wuxi JACK for over decade since the year of 2009, and witnessed rapid growth ever since, in sub-division of light duty and medium duty welded H Beam/ I Beam/T Beam production;
2) Market Boom: Recent years also see rapid demand on small size model of the 3 in 1 H Beam machine, aiming on producing small H Beams and T Beams. Which usually has specifications of:
- H Beam flange width and web height not up to 500mm;
- H Beam flange and web thickness in the scope of 3mm ~ 12mm;
a) Comparison between standard size and ultra-light H Beam from the machine;
b) The Application of Light duty and Ultra-light duty H Beam, and its produced 3 in 1 H Beam machine;
c) Wuxi JACK’s Action on Upgrade of this Automatic 3 in 1 machine
1) 3 in 1 H Beam Assembly Welding Straightening Machine;
2) Automatic 3 in 1 H Beam Production Machine;
3) Pull Through H Beam Welder;
4) Integral function 3 in 1 H Beam Welding Machine, etc.;
Please check below two sketches on:
Illustration of finished welding H Beam/ I Beam produced from the machine: (Fig.1)
1) For a piece of welded H Beam/ I Beam, the critical sizes are:
a) Web height H;
b) flange width B;
c) Web thickness A;
d) flange thickness T;
a) Max. Width of H Beam Flange: 800mm;
b) Max. height of H Beam Web: 3 grades of 1,500/1,800/ 2,000mm, which corresponds with three standard models of the 3 in 1 H Beam machine ZHJ15/ ZHJ18/ ZHJ20;
c) The most often selected model is ZHJ15, which can produce majority of necessary H Beam in application;
d) Max. Thickness of H Beam web: 32mm;
e) Max. Thickness of H Beam flange: 40mm;
It is around half of the standard web height and flange width; One third of flange and web thickness:
a) The max. web height: About 750mm ~ 1,000mm;
b) Average flange width 150mm~ 200mm;
c) flange and web thickness: Only about 10~12mm, which is close to bottom limit of workpiece produced with standard models of the machine.
So, what is the sub-division application area of such light duty and ultra light duty H Beam/ I Beam?
1. As we know, the standard sized welded H Beam is usually used in steel structure constructions for building facility/ stadium, etc.;
2. While for much smaller size H Beam, these structure members are often used in Civil Building/ Shipbuilding, etc. Which, has seen rapid market demand and huge market potential in recent years;
In July 2021, a set of ZHJ10 model machine, for building welded H Beam with:
1) Flange width up to 500mm;
2) Web height up to 1000mm;
Was shipped from Wuxi JACK to an overseas customer;
3) This is the 3rd sets of such tailor made light duty 3 in 1 H Beam machine delivered to overseas market by Wuxi JACK by the middle of 2021;
4) The other two sets of such smaller size tailor made 3 in 1 Pull Through H Beam Welder equipment were made for customer in Ethiopia and Southeast respectively.
1) Challenge: As a Chinese saying goes, “Quantitative change brings along qualitative change ”. For design and manufacture of the machine, the reduction in its workpiece does not equal to simple decrease on machine size;
2) Actions Taken: The stress calculation/ structure verification/ welding technique need to be made start from scratch again, based on experience on standard models of the 3 in 1 machine;
3) Value Chain: With the same structure and working principle as standard models, these special made automatic 3 in 1 machine have been redesigned/ manufactured and validated, making it a perfect product for customer;
a) Adopt CO2 MIG/MAG welding to substitute the original SAW (Submerged arc welding) in welding mode of the machine;
b) When Use SAW: As we know, SAW is applicable in welding of medium and large thickness of steel structure workpieces, thanks to its large current/ Big welding cover and deep penetration. So, it takes majority position in the 3 in 1 machine;
c) When Use CO2: While for H Beam flange thickness less than 10mm, even 5~6mm, CO2 MIG and MAG are much better in producing light duty and ultra light duty workpiece;
a) As we know, in standard size 3 in 1 machine, there is a rule of thumb in the relationship between flange width and thickness that can be straightened;
b) With the size diminish in flange, these data need to be analyzed and validate again. Anyway, the smaller the size, the more difficult to be straightened.
1) As the first producer who put the mature and good quality Integral function 3 in 1 H Beam Welding Machine into market in the year of 2009, Wuxi JACK always keep leading edge in this sub-division area;
2) Over the past decades, we have produced and delivered over ten hundreds of such 3 in 1 H Beam machine of various model and structure, including standard ones and special made ones;
3) We always take the first brunt in new challenge and development. For more detail, please check product family of the machine;
4) As a well established producer for welding and cutting equipment, Wuxi JACK also produces other quality products, for example, Welding Manipulators, Plate Butt Joining Machine, etc. Please check.
