e) Summary on Wuxi JACK 3 in 1 H Beam machine
A. How to Produce Heavy duty H Beam with Integral Function 3 in 1 SAW H Beam Welding Machine?
1. Confinement on 2 Passes of Welding Seam with 3 in 1 H Beam Fabrication Machine:
1) Yes, it is possible to make two passes of welding on H Beam, by sending the H Beam to the 3 in 1 H Beam machine the 2nd time;
2) In theory, in extreme cases, all the H Beam (This means 100% of workpieces) can be welded with two passes in the 3 in 1 H Beam integral machine, if customers do not care for productivity;
3) But obviously, this is not the best solution for customers in terms of both productivity and cost effectiveness;
2. Recommended Proposal with H Beam Building and Straightening Machine:
1) Under the condition over 40% workpieces need to be welded with two passes, we recommend a set of SAW H Beam Welding Machine, for implementing on 45° fillet welding, this can get better appearance of welding seam, and higher productivity;
2) A set of Wuxi JACK LHA model SAW H Beam Welding Machine, and its 2 pieces of fabricated H Beam: (Fig.1)
3) Rule of Thumb: The workpieces which should be welded with two passes in 3 in 1 H Beam machine had better not exceed 10%~ 20%, this is recommendation from the viewpoint of ideal productivity.
B. How to Determine the Most Appropriate Configuration of 3 in 1 H Beam Building and Straightening Machine?
1. Division of Workpieces Between 2 Major Categories of H Beam Steel Structure Fabrication Equipment:
1) As we know, in the field of H Beam Steel Structure Fabrication Equipment, PHJ and ZHJ series 3 in 1 H Beam Fabrication Machine has clearly different applicable working parts, from that of typical H Beam Production Line;
2) Of which, H Beam 3 in 1 Integral Machine has unmatched advantages for producing light to medium duty T Beam/ H Beam:
The welded H Beam produced from Wuxi JACK 3 in 1 SAW H Beam Welding Machine: (Fig.2)
3) While H Beam Production Line has the unique capability on producing heavy duty H Beam;
4) Here, the distinction between light to medium duty H Beam, with heavy duty ones, lies in requirement on size of welding leg: 8mm to 12mm welding seam height;
2. The Practical Issues Encountered with Customers When Purchasing H Beam Building and Straightening Machine:
1) Ideal Condition: In practical application, if customers have their workpieces clearly falling within either scope of specification mentioned above, this is a simple choice to made;
2) Dilemma: However, many times sees hybrid distribution of H Beams with specifications falling within the scope of both H Beam Fabrication Machine and H Beam Production Line, which is a hard choice to made;
3) For Example, customers have H Beams with flange thickness from 6mm up to 32mm, which cross the line between the 2 types of H Beam Steel Structure Fabrication Equipment;
4) Proposal: Under such condition, we recommend combined solution of H Beam Assembly Welding Straightening Integral Machine together with SAW H Beam Welding Machine. This will not only meet customer demand on producing various sizes of welding H Beam, but also maintain investment on equipment at the minimum level;

C. Welding Seam Penetration in 3 in 1 H Beam Assembly Welding Straightening Integral Machine:
1. Full Penetration Seam on H Beam Steel Structure Fabrication Equipment:
One of the questions customer posed is, is below welding seam penetration available from 3 in 1 H Beam machine? (Fig.3)
2. For 3 in 1 H Beam Fabrication Machine:
Wuxi JACK engineering team suggestion is no. Because:
1) For welding web with full or partial bevel, the welding current should be large: Over 700A to 800A;
2) While for working welding current of the Integral Function 3 in 1 SAW H Beam Welding Machine, the most frequently selected welding current range is around 500A~ 600A;
3) Although the 3 in 1 machine is equipped with 1000A specification SAW welding power supply, when welding current exceeds 700A~ 800A, the formed welding seam will sink down;
4) The web with full or partial bevel should be welded in SAW H Beam Welding Machine with 45° fillet welding: Not only considering eligible welding current, but also the best quality of welding seam;
3. Recommended Welding Seam in Integral Function 3 in 1 SAW H Beam Welding Machine:
1) Fabricating H Beam in the position of flat welding, or 0° welding, the proper welding seam had better be partial penetration:
2) The design sketch on typical welding seam toe sizes being fabricated from 3 in 1 H Beam Assembly Welding Straightening Integral Machine: (Fig.4)
D. Tapered H Beam being Fabricated from H Beam Steel Structure Fabrication Equipment:
1. Practical Demand: During proposal exploration between customers and Wuxi JACK, many customers care on the availability of H Beam Fabrication Machine to produce tapered H Beam;
2. The feedback from Wuxi JACK is yes: The 3 in 1 H Beam machine definitely can fabricate tapered H Beam, or in other words, variable cross section H Beam;
3. Specification: Meanwhile, the maximum slant angle should not exceed 8°. Which, in practical Steel Structure Industry, is fairly a large angular scope, and can meet most majority, or, close to 100% of customer demand on this aspect;
4. Hand made sketch on tapered H Beam, that can be produced from Wuxi JACK Integral Function 3 in 1 SAW H Beam Welding Machine: (Fig.5)
E. Summary on Wuxi JACK 3 in 1 H Beam Fabrication Machine:
1. There are really large quantity of discussions and exploration between customers and Wuxi JACK, in numerous commercial cases of related H Beam Steel Structure Fabrication Equipment;
2. Such discussion is beneficial to both sides: It not only helps getting the most fitting technical solution for customers, but also inspiration source of Continuous Improvement on the machine;
3. Significance: As the leader on rendering the best H Beam Building and Straightening Machine for customers of so many years, such effective communication also makes great contribution, on helping Wuxi JACK maintaining our leading position on this product family.
