2) Every time H Beam sizes change, welding torches need to be moved along 3 directions before welding:
a) X axis horizontal;
b) Y axis vertical;
c) 45° oblique angle,
So as to maintain welding torch always to be positioned at welding seam accurately;
3) Always Aiming on Welding Seam Precisely: In Wuxi JACK produced three in one Integral Function H Beam Welding Machine, our welding torch mechanism has excellent capability on flexible and convenient modulation on its position, benefitting from ingenious design and delicate workmanship of this mechanism;
4) Protection on H Beam and Machine Assembly: Besides, when feeding in and sending out T I H Beam into and out of machine central function units, the two sets of welding torches should be moved away, to leave sufficient space for workpiece movement, so as to avoid collision with each other. This can give the best protection on both workpiece and function units of welding 3 in 1 H Beam Machine itself;

 

2. Welding Torch Position Change in Wuxi JACK 3 in 1 Integral Function H Beam Welding Machine:

Shown from the above photos, in Wuxi JACK manufactured assembly welding straightening H Beam 3 in 1 Production Machine, under motor drive, the welding torches can be adjusted along spatial directions of:

2. This is the reason why this machine focuses on producing light to medium duty welding T I H Beam (“Light to medium duty” refer to: The finished welding seam have toe size of 8~ 12mm);
3. The second feature in working modes of the machine is, benefitting from its integrating assembly/ welding/ straightening units together in a row in its function unit, T Beams and H Beams are produced from steel plates with its passing through of the machine: The first time flange and web pass through is fabricated into T Beam; The second time pass through is fabricated into H Beam. This is the reason the machine is often called “Assembly welding straightening 3 in 1 H Beam Machine”;
4. Welding Modes: Over 90% of applicating cases of the machine is with Single Arc/ Twin Arc/ Tandem Arc SAW (Submerged arc welding): The finished T I H Beam flange and web plate thickness is 6mm ~ 40mm; Under 10% customer choose GMAW CO2 gas shielded welding, for producing 3mm ~ 6mm plate small thickness T H Beams.

Technical Evolution on Wuxi JACK Assembly Welding Straightening 3 in 1 H Beam Machine

Journey: From year 2009 as pioneer on this machine, to today in Nov. 2025 year as backbone supplier, Wuxi JACK 3 in 1 Integral Function H Beam Welding Machine experiences technical evolution with time going, advancing toward better performance, more reasonable structure and operation. The tenet behind our hard work is: “There is never the best, there is always the better waiting ahead”.
Below are 4 typical upgrades on machine design and equipment over the past 10 year from 2015 to today 2025 year ending, that notable for record:
 

1. Welding Torch Mechanism of 3 in 1 Integral Function H Beam Welding Machine:

1) Before: Welding Torch Mechanism of Assembly Welding Straightening 3 in 1 H Beam Machine:

1 Fig1 Welding H Beam 3 in 1 Production Machine 209
a) As shown in the above photo, that there is no means for adjusting and guaranteeing precise position of welding torches;
b) Accordingly, operators should command on proficient skill, on manipulating welding torch positions;
c) Besides, even after welding torch position is adjusted to correct level, it is easy to drift away during welding operation, because of no fixture on welding torches;
d) Thus, welding torch position and hence quality can not be fully controlled, and operator needs to watch on welding process all the while;
e) Need to emphasize is, until today by November 2025 year, over 90% companies still have their welding torch mechanism in such design;
 

2) After: Welding Torch Mechanism of Assembly Welding Straightening 3 in 1 H Beam Machine:

a) Around 10 years ago in year 2015, Wuxi JACK engineers gave full play to their intelligence and wit, absorbing feedbacks from customers, and introduce new type of welding torch mechanism in our 3 in 1 Integral Function H Beam Welding Machine, as shown in below photo:
2 Fig2 Three in One H Beam Assembly Welding Straightening Integral Machine 12
b) Welding torch is installed onto a motor drive cross slides, with high precision linear guiderails installed along horizontal and vertical directions. The welding torch itself is oriented in 45° slant angle;
c) In this way, operator can easily modulate on position of welding torch in precise way, and position is maintained during the entire welding period without any drift;
d) This can not only fully guarantee on welding performance, but also relieves operator labor intensity during operation: Operator just need to sit alongside, to watch on machine operation;
e) Until today by November 2025 year, in this industry, still only Wuxi JACK has such ingenious design on welding torch mechanisms of our H Beam 3 in 1 Production Machine.

 

2. Downward Pressing Roller Mechanism of Assembly Welding Straightening H Beam 3 in 1 Production Machine:

This is another critical point in technical aspect, which differs Wuxi JACK welding 3 in 1 H Beam Machine from other producers:
1) Transient Design on Downward Press Roller:
There had once been over short period, our H Beam upper flange press roller is with this design, that its up and down guidance is by means of 4 pieces of rollers, as shown in the below photo:
3 Fig3 Three in One H Beam Assembly Welding Straightening Integral Machine 163

2) Revised Design in Assembly Welding Straightening 3 in 1 H Beam Machine:

a) But soon we found out that, such design is not so stable and durable, especially after long time use, although it can reduce manufacturing cost, and hence bring along more profit to us;
b) Accordingly, Wuxi JACK engineers adopted again the original design of downward press unit, of rectangular box structure, guided with 4 pieces of heavy duty linear guiderails. In this way, the contact gliding surface area is greatly enlarged, promising more stable/ reliable / durable holding on flange and web during T H Beam fabrication:
4 Fig4 Three in One H Beam Assembly Welding Straightening Integral Machine 179
c) Need to emphasize is, until today by November 2025, such design is unique label of Wuxi JACK 3 in 1 Integral Function H Beam Welding Machine: That if you find such structure, you can 100% sure this machine is produced by Wuxi JACK.

3. Lateral Mechanical Base Bed of PHJ Models Assembly Welding Straightening 3 in 1 H Beam Machine:

The above left 2 photos compare on before and after design on pedestal of PHJ models. 
Noted: The before design itself is very good design. The reasons we changed design are:

1) Stronger mechanical strength: As can be seen from the photo, the before design is with several pieces of steel plates and assemblies fabricated together, while the new design is with integral structure;
2) Under the precondition of maintaining superior performance, new design can reduce machine production cost, so as to lower down welding 3 in 1 H Beam Machine quotation accordingly. This makes our machines more competitive in the market;
3) More convenient use: The new design is easier to clean and service, because it has more concise structure. This will bring convenience for customer operator during daily operation;
The above right 2 photos demonstrate on the old and new design of, erected Wuxi JACK PHJ models assembly welding straightening 3 in 1 H Beam Machine;
Complement: Mechanical base structure of ZHJ models is different from PHJ series, and always kept unchanged over the past 16 years from 2009 to 2025. It is classical design.

4. Welding Power Supply Equipped with 3 in 1 Integral Function H Beam Welding Machine:

This is another great leap forward in development history of assembly welding straightening H Beam 3 in 1 Production Machine:
a) At early stages of this machine, welding power supplies were all Lincoln brand, D.C1000 for single arc SAW in majority, or DC1250 plus AC1200 for tandem arc SAW;
b) Later years see rapid development of Chinese local brand welding machines, especially after year 2015, Chinese welding machines gradually taken place of Lincoln brand, because of its merits of:
1) Cost effectiveness: Much lower price, and good quality. This helps companies offer more affordable machine quotation for customers;
2) More shorter lead time, benefit for shortening lead time of welding 3 in 1 H Beam Machine accordingly;
3) More quick reaction on after sale service, this is easy to understand, that it is more time saving to communicate with engineers in China than in America;
 

2 stages of SAW welding machines to be equipped with 3 in 1 Integral Function H Beam Welding Machine:

American Lincoln Brand
Chinese Local Brand
Today by end of year 2025, Chinese local brand welding power supply takes over 90% of market share in the field of welding 3 in 1 H Beam Machine. It is default configuration of machine, unless customers specifically designate other brands.

FAQ on Wuxi JACK Three in One Integral Function H Beam Welding Machine

Below are some frequently asked questions from customers, when consider and communicate with us purchasing welding H Beam 3 in 1 Production Machine. Especially over the past recent years to end of year 2025:
 

  • Q What is standard on Distinguishing medium duty H Beam for Welding 3 in 1 H Beam Machine, and heavy duty H Beam for H Beam Production Line?

    A
    1. 1) There is no explicit definition and distinction between medium and heavy duty H Beam in Steel Structure industry. In common practice, 12mm toe height welding seam is the threshold for distinguishing heavy and medium duty H Beam;
    2. 2) Three in One Integral Function H Beam Welding Machine can complete 12mm welding toe on finished H Beam with single time welding pass; For heavier duty workpieces with 12mm bigger welding seam, H Beam Gantry SAW Welding Machine should be used, which can be referred to as “heavy welding”;
    3. 3) The 2 machines have different welding orientations when welding on H Beam, 0° versus 45°.

  • Q What is Welding Mode adopted in Wuxi JACK Three in One Integral Function H Beam Welding Machine?

    A
    1. 1) Majority of welding 3 in 1 H Beam Machine is equipped with single arc 1000A SAW (Submerged arc welding), which is applicable for producing 10mm ~ 40mm thickness flange and web;
    2. 2) When producing small thickness H Beam, namely 3mm to 10mm, the more proper welding mode is 500A CO2 GMAW;
    3. 3) When customers seek on the Max. welding efficiency, twin arc/ tandem arc SAW is considered configuration: A.C.1250A and D.C.1200A. The downside of such choice is high cost on machine purchase: 4 sets of welding power supply compared with 2 sets;
    This is featured function of Wuxi JACK assembly welding straightening H Beam 3 in 1 Production Machine.

  • Q What is Recommended Welding Process Parameters, in Wuxi JACK Three in One Integral Function H Beam Welding Machine?

    A
    1. 1) Welding Current: When working in SAW welding model, for flange and web thickness 20mm~ 30mm, the suggestive welding current is around 550~ 750A; When working with CO2 GMAW on 5mm to 6mm thickness, 350A welding current is often adjusted;
    2. 2) Welding Speed: Customers care on this parameter the most, because it directly determines H Beam productivity. Although some producers claim on 1700 to 1800 mm/min., the proper Max. welding speed should be 1200 mm/min., this is determined by welding technology, not the welding 3 in 1 H Beam Machine itself. Too high improper welding velocity will lead to insufficient welding seam fusion, and thus inferior welding quality.

  • Q What is Application Form of Assembly Welding Straightening H Beam 3 in 1 Production Machine?

    A There are two primary common seen ways of deployment on welding 3 in 1 H Beam Machine:
    1. 1) Installed and operated as individual equipment. Some customers purchase single set machine, some customers purchase two or more sets, but all in the way of individual. So, in the case of two or more machines, these machines are installed certain distance apart, to fulfil different jobs;
    2. 2) Composed into new type of welding H Beam Production Line, different from conventional lines. This new line is composed of 2 sets of three in one Integral Function H Beam Welding Machine, in the form of staggered straight line at workshop, with deviation of conveyor width. In this way, H Beam welding can be completed with its moving through the 2 sets of machines in a row. For the purpose of saving labor intensity, some customers also ask on group of hydraulic drive 90° Overturning Table, to be situated between the 2 sets of welding 3 in 1 H Beam Machine.

  • Q Why T Beam H Beam is Orientated in Vertical, during its Manufacture, in Assembly Welding Straightening 3 in 1 H Beam Machine?

    A
    1. 1) This is the questions often raised by South Asia customers, especially Indian customers. By the time end of 2025 year, every time Indian customer inquired on welding H Beam 3 in 1 Production Machine, they asked this question;
    2. 2) The reason may lies in the way of their H Beam production, which is based on American standard, that H Beam is situated in horizontal, and fairly percentage of conditions, H Beams are welded only with single side, the opposing side is not welded;
    3. 3) Comparatively, in other countries and regions including China, H Beams are usually produced in vertical way, that H Beam will be flipped 180° one time in the process, to weld on its both sides. This is popular way of process technology being applied in three in one Integral Function H Beam Welding Machine.

  • Q Are There any Details that Easily to be Neglected by Customers when Purchasing 3 in 1 Integral Function H Beam Welding Machine?

    A Yes, although customers usually spend long time investigating on machines before purchase, they are not insiders, and sometimes may encounter manufacturers, that although looks good proposal is proposed, some details are not mentioned or underlined in purpose, which, in the stage of purchase it looks unimportant, but plays key role in subsequent official running;
    In the case of Assembly Welding Straightening 3 in 1 H Beam Machine, some examples on this aspect, from year 2009 to end of year 2025:
    1. 1) Straightening capacity on H Beam flange thickness: Although very often seen H Beam plate in the thickness around 20mm, which looks acceptable at the beginning, but imagine on in the following 10+s year machine service life, that customers will inevitably come across producing on 30 to 40mm thickness H Beam, and only Wuxi JACK produced assembly welding straightening H Beam 3 in 1 Production Machine can fulfil such task;
    2. 2) Capacity of SAW Flux Hopper: Yes, this is an even nuisance technical index, that if not emphasized, over 95% customer will not pay attention on it. A real case is, in this year 2025, Wuxi JACK had a Columbia customer, who planned to purchase the 2nd set of their three in one Integral Function H Beam Welding Machine. 10 years ago they bought their first set from another Chinese company, that capacity of SAW flux hopper is only 50kg. This time, they took lessons, and noted that Wuxi JACK equipped capacity is 100kg for our SAW flux hopper;
    “Detail determines excellence”, the above 2 technical data, and other technical characteristics of our welding 3 in 1 H Beam Machine, help us winning this South American customer in Aug. 2025 year.
