The Market Boom on Light-duty H Beam Fabrication Machine

Preface:

H Beam Fabrication Machine, the other name includes H Beam Assembly Welding Straightening Machine/ Automatic H Beam Production Machine/ Pull Through H Beam Welder/ Integral-function H Beam Welding Machine, etc., has been put into market for over decade since 2009, and witnessed rapid growth ever since, in sub-division of light-duty and medium-duty welding H Beam/ I Beam/T Beam production. Recent years also see rapid demand on small size H Beam Fabrication Machine. This short article will focus on this subject.

The topics in this article:

  • Comparison between standard size and ultralight H Beam;

  • The Application of Light-duty and Ultralight-duty H Beam, and its H Beam Welding Machine;

  • Wuxi JACK’s Action on Upgrade of Automatic H Beam Production Machine



1. Comparison between Standard Size and Ultralight H Beam:

Please check below two sketches on illustration of welding H Beam/ I Beam made with Automatic H Beam Production Machine.

  • For a piece of welding H Beam/ I Beam, the critical size is web height H, flange width B, web thickness A, and flange thickness T;

  • For “normal” or standard size of H Beam/ I Beam, the flange width is up to 800mm; Web height up has 3 grades of up to 1.5m/1.8m/ 2.0m (Corresponds with three standard models of integral function H Beam Welding Machine), of which the most popular is 1.5m; The max. thickness for web and flange are 32mm and 40mm respectively;

  • For “Ultralight” or small size of H Beam/ I Beam, it is around half of the above dimension, and one-third of thickness: The max. web height is about 0.75m~ 1m, average width 150mm~ 200mm; As to web/flange width, only about 10~12mm, which is close to bottom limit of workpiece produced with standard H Beam Assembly Welding Straightening Machine.


2. The Application of Light-duty and Superlight-duty H Beam and Its H Beam Welding Machine:

  • So, what is the sub-division application area of such light-duty and ultra-light duty H Beam/I Beam? As we know, the standard-sized welding H Beam produced with Pull Through H Beam Welder is usually used in steel structure constructions for building facility/ stadium, etc.;

  • While for much smaller size of light-duty and ultralight- duty, 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 ZHJ5010 (For building flange width up to 500mm, and web height up to 1000mm) Integral Function H Beam Welding Machine (H Beam Fabrication Machine) was shipped from Wuxi JACK to a customer in Chelyabinsk, Russia. This is the 3rd sets of such tailor-made light-duty H Beam Assembly Welding Straightening Machine delivered to overseas market by Wuxi JACK by the middle of 2021, the other two sets of such smaller-size tailor-made Pull Through H Beam Welder were made for customer in Ethiopia and Southeast respectively.


3. Wuxi JACK’s Action on Upgrade of Automatic H Beam Production Machine:

  • So, as a renowned producer for H Beam Fabrication Machine, what should we do to cater for customer demand? As a Chinese saying goes, “Quantitative change brings along qualitative change ”. For design and manufacture of integral function H Beam Welding Machine, the reduction in its workpiece does not equal to simple decrease on machine size. The stress calculation/ structure verification/ welding technique need to be made start from scratch again, based on experience on standard models of H Beam Fabrication Machine (Pull Through H Beam Welder);

  • With the same structure and working principle as standard models, these special-made Automatic H Beam Production Machine have been redesigned/ manufactured and validated, making it a perfect product for customer;

  • Examples on upgrade:

1)   Adopt CO2 MIG/MAG welding to substitute the original SAW (Submerged arc welding) in welding mode of the Automatic H Beam Production Machine. 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 integral function H Beam Welding Machine; While for thickness below 10mm, even 5~6mm, CO2 MIG/MAG is much better in producing light-duty and ultra-light-duty workpiece;

2)  Straightening Capacity for Flange: As we know, in standard size H Beam Welding Machine, there is a rule of thumb in the relationship between flange width and thickness that can be straightened. 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.


4. Summary:

As the first producer who put the mature and good-quality Integral function H Beam Welding Machine (H Beam Fabrication Machine) into market in the year of 2009, Wuxi JACK always keep leading edge in this sub-division area. Over the past decades, we have produced and delivered over ten-hundreds of such Pull Through H Beam Welder of various model and structure, including standard ones and special-made ones. We always take the first brunt in new challenge and development. For more detail, please check product family of H Beam Assembly Welding Straightening Machine;

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.
