Q: What does “Open Mechanical Structure” refer to for I H-beam Welding Machine?

1) This means: Workpieces (BOX I H Beams) are put onto external open section of mechanical main body of machine, thus “no restriction” on size (height) of workpieces, especially height; 2) In LHC model, H Beam is laid on hydraulic drive 60° Overturning Racks alongside the LHC moving trolley. This motorized moving trolley moves along the H Beam during SAW welding; 3) In LHT model, the 2 pieces of H Beams are laid on the 2 arrays of supporting racks, which are at external both lateral sides of machine; 4) Customer determine and select on which type of I H-beam Welding Machine is better for operation, depending on H Beam specifications / process technology design/ workshop layout plan/ budget level of customer facility.

Q: What are Advantages of Open Frame I H-beam Gantry SAW Welding Machine?

1) One Size fits for All: Because there is no confinement on placement of workpiece (BOX I H Beams) in open structure, so, size range of applicable workpieces has great extensive range than enclosed gantry frame types machines. In other words, when customer plan to produce new batch of H Beam, they do not need to fret over whether the current open structure I H-beam Welding Machine is applicable or not; 2) So, any sizes of H Beam, from the smallest web height 200mm, to the max. web height 2000mm, can be placed into LHC or LHT open frame machines; 3) Besides, other common seen steel structure workpieces, especially BOX Beam, can also be welded in open structure machines; 4) When customer plan to introduce new types of workpieces, say, long pipe/ post... the existing open structure machine can also be used without or with very few modifications on the existing machine.

Q: What are Welding Mode and Operation in Open Structure H-beam Gantry SAW Welding Machine?

1) Major Welding Mode: 45° fillet SAW welding is the No.1 choice to be implemented in all models of machine. And, among this, majority is with single arc SAW welding; When customer need higher welding velocity, or thickness of H Beam flange and web are larger than 60mm, tandem arc SAW should be used; 2) Promise Heavy Welding: The strongest point of sole purpose I H-beam Welding Machine is to get solid welding seam formation in fabricated BOX T I H Beams, which guarantees sufficient penetration depth/ broad cover face of formed welding seam on finished workpieces; 3) Mature Welding Technique: SAW and other types of welding is managed by means of professional welding power supply (Single/ twin/ tandem arc welding machines), together with system of assistant welding operation, including welding torch position detect and control, welding wire feeding and straining unit, etc.; 4) Welding velocity is managed with A.C. inverter, and displayed real time intuitively in digital meter of machine operating panel.

Question 1

In terms of technical topics between customer and Wuxi JACK engineering team on I Beam and H Beam Flange Edge Rounding Machine, what is the most impressive topic over the past 2 decades, from Year 2009 to now (February 2026)?

Accepted Answer

Undoubtedly, the most impressive one is scope of workpiece (I Beam and H Beam) specifications, that can be edge rounded. The 2 cases that is worthwhile to mention here are:

1) In April 2023, a Singapore customer communicated with Wuxi JACK on HR800 model I H Beam Flange Edge Rounding Machine. The focus between both sides is the minimum size of H Beam that can be edge rounded: The conventional specification on minimum of flange thickness is 10mm, and 8mm under special design. Which means, the 8mm thickness/ 100mm flange width is the lower limit of workpiece size; Customer wanted to have the machine capable of edge rounding on H Beam with flange the minimum thickness of 6mm. Accordingly, according to Wuxi JACK engineer, slant angle of edge roller is around 10°, it should be 15° to available on edge rounding smaller H Beam. Correspondingly, edge rounding roller should be larger;
2) In beginning of February 2026, a west European customer contacted with Wuxi JACK, on I Beam H Beam Flange Edge Rounding Machine, for series of large projects which will kicked off in year 2027. Customer gave us list of all European standard I Beams and H Beams, which is planned to be processed. On that basis, Wuxi JACK engineer identify the workpiece list one by one, and gave customer response on whether our Flange Edge Rounding Machine can cover all the workpieces customer raised, and which sizes of I H Beam can be edge rounded, which can not be edge rounded, because of too small width and thickness of I H Beam flange.

Question 2

What do Customers Care on Technical Service on End Plate Trimming Machine?

Accepted Answer

Take the same west European customer who communicates with Wuxi JACK in February 2026 as example, below are questions raised by customer on technical service on the European standard I Beam H Beam Flange Edge Rounding Machine:

1) What is freight cost to ship to customer city port, and also install the machine in customer workshop and give training to operators? Customer can unload using overhead cranes at their workshop;
2) What is cost of import taxes on the machine?
3) How much time is needed to transport and install in customer workshop?
4) What is cost and delivery times for a complete set of consumables and edge rounding rollers?
5) Are there partners in customer country, for maintenance and repair of the I Beam H Beam Flange Edge Rounding Machine?
6) Response time for a service intervention?
7) How much maintenance does the machine require?

Question 3

What are Consumables for Running on Steel Plate and I H Beam Flange Edge Rounding Machine?

Accepted Answer

1) Although with complicated structure and energy source, the machine daily operation cost is low. It only has one type of consumables: The 4 pieces of edge rounding rollers;
2) Operated and maintained properly, expected service life of each piece of edge rounding rollers is around 50,000m edge rounding length;
3) Process technology: These edge rounding rollers are solid type, made of 35CrMo tool steel, finely machined in machining center, then tempered integrally, and have its surface quenched, making sure its stable and durable long time performance.

Question 4

Is it Safe to Operate on Wuxi JACK I Beam H Beam Flange and Metal Steel Plate Edge Rounding Machine?

Accepted Answer

1) Any automatic machine exists certain potential risk on operation and service, if not carried out carefully and properly. On the other hand, safety is the foremost factor to be taken for both customer and supplier, especially heavy duty mechanical equipment. This is always tenet of Wuxi JACK engineers developing our machines;
2) For this RH series End Plate Trimming Machine, the deburring and edge rounding speed of 7200mm/min. is fairly fast, and operator working around it should take precaution;
3) So, what is the Design of Wuxi JACK Edge Rounding Machine for Safety Purpose?

a) The design of the mechanical structure makes edge rounding unit is located at middle of the machine mechanical frame. Which means, it is difficult to have direct access to working area of the machine by operators;
b) Besides, to have a double insurance, we have Emergency Stop buttons deployed at both inlet and outlet side of machine main frame;
c) Alarm lights and limit switches are also installed at eye catching position, and at ends of execution unit movement stroke.

Question 5

Why there are 4 sets of LHC H Beam Welding Machine in automatic H Beam Production Line, but only 1 set of T Beam H Beam Assembly Machine?

Accepted Answer

Because in operating pace of automatic H Beam Production Line, welding station is bottle neck:

1) The SAW submerged arc welding speed is in the range of 100- 1000mm/min., and one set of LHC H Beam Welding Machine welds on one seam at one moment;
2) Comparatively, in H Beam Assembly and CO2 Tack Welding Machine, the assembly speed is in the range of 240- 2400mm/min., and one set of assembly machine welds on two seams at any moment;

To align assembly speed with SAW welding speed into same level, so as to acquire ideal line balance rate (85% plus) and smooth material flow, there are 4 sets of H Beam Welding Machine in H Beam Production Line, and only one set of T Beam H Beam Assembly Machine to work with.

Question 6

Besides Standard Functions of Assembly and CO2 Tack Welding, are there any Variations with Configurations of T Beam H Beam Assembly Machine, to get More Flexible Choice on Operation at Customer Facility?

Accepted Answer

Yes. This is the request often raised by customers, so as to not only get the best utilization of machine, but also optimal financial return on investment. For example:

1) In August 2025 year, when a Cambodian customer planned to purchase 2 sets of Z15 H Beam Assembly and CO2 Tack Welding Machine from Wuxi JACK, they requested the machines not only to be equipped with conventional CO₂ tack welding function, but also with SAW continuous welding ability. For this reason, each one set of the machine is equipped with 4 sets of welding power supplies: 2 sets of 500A GMAW welding machine, and 2 sets of 1000A single arc SAW welding machine. This helps the machine with multiple choice on welding mode and applicable H Beams for production. These 2 sets of Z15 model T Beam H Beam Assembly Machine are scheduled to be shipped to Sihanouk at end of January, 2026 by sea transportation;
2) Also in early January 2026 year, when an Indian customer had technical communication with Wuxi JACK engineer on the machine, he raised the same request. The customer expectation is to have the machine not only capable of producing semi-finished welding H Beam of large size, but also be able to produce finished welding H Beam directly with 500A GMAW welding machine, in the form of continuous CO₂ gas shielded welding;
3) Besides, Wuxi JACK engineers can also propose the T Beam H Beam Assembly Machine to be equipped with Twin arc/ Tandem arc SAW welding machines. In this way, in the case of continuous SAW or GMAW welding, the welding speed can be doubled compared with conventional single arc welding mode, so as to acquire on double productivity on H Beam Production Line.

Question 7

How to Select Proper Model and Specification of I H Beam Assembly Machine?

Accepted Answer

Below checklists need to be considered before decision making:

1) H Beam Size:

a) The max. web height of T Beam H Beam: Corresponds with models of Z15 (1500mm) / Z18 / Z20/ Z25/ Z30;
b) Other important specification: The max. flange and web thickness; Flange width, this determines the max. capacity of machine;

For example, in early January 2026, when an Indian customer raised inquiry and request to Wuxi JACK engineer, he wanted to have the machine with capability of producing H Beam with the max. sizes of:

a) H Beam web height up to 3000mm, which should be Z30;
b) H Beam flange width 1200mm- 400mm wider than common seen 800mm;
c) H Beam flange thickness 100mm;
d) H Beam web thickness 60mm;

Very heavy duty, a rather challenge on producer of I H Beam Assembly and Tack Welding Machine;

2) Control Mode: Assembly and tack welding, customer prefer automatic type, or manual?
3) Are there any other special requirement from customers on the machine?

Also take this Indian customer who talked with Wuxi JACK engineer in early January 2026 as example again, he hopes I H Beam Assembly Machine to be capable of performing not only CO₂ stitch welding, but also continuous CO₂ welding, so as to have finished welding on small H Beam with the same set of machine. In this way, customer can save cost on machine purchase, and has more flexibility to arrange on different specifications H Beam production.

Question 13

What are Supply Range of Various types of I H-beam Welding Machine, including LHA series Gantry Frame, LHC model Trolley Column, and LHT model Open Structure?

Accepted Answer

1. This is a good question, that often neglect by customer and supplier company, and sometimes cause controversy. For example, in end of December 2025, when a Vietnam customer communicated with Wuxi JACK on LHA model H-beam Gantry SAW Welding Machine, we forgot to remind customer that, the 18m long parallel rails for gantry movement is not included supply range, because unlike rails of CNC Flame Plasma Cutting Machine, which need to be machined, for rails of I H-beam Welding Machine, the parallel rails do not need to be machined, do, it is not in scope of supply. This is common practice, but need to confirm with customer when making quotation;
2. Basically, supply scope of all types of I H-beam Welding Machine:

1) Mechanical main frame, including motor drive moving trolley for LHC, gantry frame for LHA, and T frame open structure for LHT;
2) SAW welding system, including different types of welding machines, welding torch mechanism, supplementary welding units, flux conveying and reuse machines;
3) Drive and transmission system on mechanical main frame;
4) Electric control system of machine;

3. Unless specifically designated by customer and negotiated accordingly, supply range of I H-beam Welding Machine do not include:

1) 2 arrays of triangular H Beam support rack;
2) Parallel rails for frame movement;
3) Cable overhang racks;

But we provide drawing of these items for customer producing these items. The reason we do not provide these items is, it is easy to produce, but have large size and heavy weight, which will greatly increase logistic cost of I H-beam Welding Machine. To save freight charge on the machine for customers, we exclude these items from supply range of the machine.

Question 14

How Many Operators are Necessary for Running on I H-beam Gantry Welding Machine?

Accepted Answer

This is another important question customer concerns during machine purchase analysis, and actually differs based on practical condition at customer site. the major factors affecting number of operators include:

1) Model and design of machine. For example, for LHA series H-beam Gantry SAW Welding Machine, there are 2 branches of: LHAC lateral operating type, which usually need 2 operators work on one machine; While one operator is sufficient for working on LHAZ middle operating type;
2) Quantity of machines on site: Especially for I H-beam Welding Machine, very often customer purchase more than one set of machine: For LHC model at automatic H-beam production line, usually 4 sets in a line; For LHA series gantry frame moving and LHT model open structure T frame I H-beam Gantry Welding Machine, one or two sets are installed in H Beam production workshop. Under ideal condition, one operator can take care on operation of 2 machines simultaneously, which can raise productivity;
3) Operator Proficiency: This is another controversy sometimes happened during business exploration. For example, also in end of December 2025, the Vietnam customer discussed with Wuxi JACK engineer on how many operator is necessary for operating on PHJ and ZHJ series 3 in 1 I H-beam Welding Machine. The Vietnam customer questioned on whether only one operator is capable of working on one set of the 3 in 1 machine, he told us that, in Vietnam factories, customer manager arrange on 2 operators to work on the machine: One as lead and one as main; On the other hand, from Wuxi JACK perspective, if operator is proficient, only one people is sufficient for managing on the 3 in 1 I H-beam Welding Machine.
