Technical Strong Points of Wuxi JACK I H Beam Assembly and Tack Welding Machine

1. Downward Press Beam of Wuxi JACK I H Beam Assembly Machine:

1) This unit design in Wuxi JACK machine is completely different from that of other producers, just like in the case of 3 in 1 H Beam Assembly Welding Straightening Machine:
2) Wuxi JACK machine (Left) downward press beam compared with other producers (Right): (Fig.1, 2)
 Fig1 I H Beam Assembly Machine 9 IMG_7195 Fig2 I H Beam Assembly Machine 4
3) Shown in the above photos, Wuxi JACK I H Beam Assembly Machine press beam has solid structure of rectangular box structure, with sliding force for driving downward movement for firmly clamping on H Beam. The manufacture cost is much higher, and performance is much reliable and smooth;
4) While in other producers’ machines, the downward press beam is guided with 4 pieces of rolling rollers, the corresponding downward movement is by means of gliding force, the corresponding performance has shorter life than Wuxi JACK products;
 

2. Overall Structure Dimension and Strength of Wuxi JACK I H Beam Assembly Machine:

1) It is not proper to paste the photo on entire set of other producers’ machine here. We just demonstrate on our main machine, to show our solid design:
2) Front view on Wuxi JACK Z15 model I H Beam Assembly Machine in year 2025, for East European customer: (Fig.3)
Fig3 I H Beam Assembly Machine 39 IMG_20250502_144327
3) The overall dimension and manufacturing cost of Wuxi JACK I H Beam Assembly Machine is far more larger and higher than other producers. Our goal is to provide durable, stable and high quality products for customers, not “Short time throwaway” products;
4) In this era of fierce competition, that many producers stealthily change their design and reduce machine manufacturing cost, so as to lower down selling price to gain more advantageous position in competition, do not truly care on real quality and subsequent performance at customer site, just for making improper profit. It is not easy to sustain belief on “Truly takes customer long term interest as 1st priority”, that Wuxi JACK insists on our design and quality of our machines. We believe customers with sagacious judgement understands value of our machines;

2) Requirement on accuracy of T Beam and H Beam fitting up, in terms of flange and web relative position;
2. Electric Control: I H Beam Assembly Machine is the only equipment in line of H Beam Welding Production Machine, which has both A.C. inverter for VF (Variable frequency drive) working speed management, and PLC (Programmable logic controller) for flexibly controlling operation logic, and can update conveniently by technician when necessary.

Work Principle of Wuxi JACK I H Beam Assembly Machine

1. The appearance and structure of I H Beam Assembly Machine is quite similar to 3 in 1 H Beam Assembly Welding Straightening Machine. From other perspective, the latter is originated from the former:
2. Customer operation site of 2 machines: Z15 model I H Beam Assembly Machine (The left one), versus PHJ15 model 3 in 1 H Beam Assembly Welding Straightening Machine (The right one): (Fig.1, 2)
Fig1 I H Beam Assembly Machine 15 Fig2 3 in 1 H Beam Assembly Welding Straightening Machine 6

3. Formation of 3 in 1 H Beam Welding Machine from I H Beam Assembly Machine:

At central function zone of the machine, right following the assembly alignment rollers,
1) Replace the original 2 sets of 350A- 500A CO2 welding power supply into 1000A- 1250A SAW type;
2) Replace the original 2 pieces of CO2 stitch welding torches to SAW continuous welding torches;
3) Add on the group of straightening rollers right following SAW continuous welding torch units;
Thus come into being 3 in 1 H Beam Welding Machine. Shown as below on comparison:
4) Central function units of Wuxi JACK I H Beam Assembly and Tack Welding Machine, versus 3 in 1 H Beam Assembly Welding Straightening Machine: (Fig.3, 4)
Fig3 I H Beam Assembly Machine 7 IMG_7187 Fig4 3 in 1 H Beam Assembly Welding Straightening Machine 326

Work Procedure of Wuxi JACK I H Beam Assembly Machine

Same as 3 in 1 H Beam Fabrication Machine, here the assembly operation is also implemented in the two steps of:

1. First Stage Rough Assembly: (The above 1st Photo) in I H Beam Assembly Machine:

1) First, rough positioning and clamping on flange and web by means of hydraulic drive manipulators (Also called pulling rod box);
2) The 2 pairs of manipulators are located in interval along machine infeed roller tables, face to face with each other in symmetry;
3) Such rough fitting up is fulfilled simultaneously, together with flange and web sending into the main machine;

2. Second Stage Precise Assembly (The above 2nd Photo) in I H Beam Assembly and Tack Welding Machine:

1) As the clamped flange and web are sent to main machine, precise positioning and clamping is carried out, by means of hydraulic oil cylinder drive alignment rollers;
2) These alignment rollers are installed in symmetry, and at different height levels, for clamping on flange and web respectively;
3) To acquired accurate assembly effect, these alignment rollers are eccentric type. Which means, position of these eccentric alignment rollers can be adjusted in inching mode, so as to manage on flange and web position correctly, acquiring full proof accurate assembly effect;

3. The above 3rd Photo: Pressing Web with Flange Firmly in Wuxi JACK I H Beam Assembly Machine:

1) During T Beam H Beam assembly and CO2 intermittent welding operation, the workpiece is pressed and held firmly by means of a piece of downward going pressing beam, which is guided with a rod;
2) This rod is driven with an overhead oil cylinder, which are installed into machine top gantry. It is the apex point of the machine;
4. Overall view on T Beam H Beam assembly in Wuxi JACK machine is shown in the above 4th photo.

B. CO2 GMAW Welding in I H Beam Assembly and Tack Welding Machine:

1. Welding mode on H Beam assembly is small to medium current CO2 gas shielded welding, majority in the form of intermittent tack welding;
2. The nominal max. welding current is 500A, and common seen working current is around 350A;

3. Welding Environment of I H Beam Assembly Machine:

1) Unlike I H Beam Submerged Arc Welding Machine, which is adopted with no fume and SAW (Submerged arc welding), CO2 GMAW generates intense heat, fumes, noises, strong arc light;
2) Accordingly, as shown in above photos, operators need to put on proper PPE (Personal protection equipment) for maintaining personnel safety, especially helmet/ glove/ goggles;
3) The CO2 welding torches should be equipped with water cooling function, to maintain its service life.
