1) There are 10+ types of H Beam Machines in production line, covering steps of: Assembly, SAW welding, flange straightening, horizontal press longitudinal straightening, 60°/ 90°/ 180° flipping, end face milling;
2) In each type of machine, there are several structures and models, to best suitable for customer need. For example, for H Beam SAW Welding Machine, customers has options of: LHC trolley boom structure, or LHA gantry frame, or LHT open T frame, based on whether automatic or semi-automatic line, and the max. size of H Beam, especially web height, flange width and thickness;
3) With over 20 years technical accumulation and experience, as professional and renowned H Beam Production Line Supplier, Wuxi JACK strives on provide the top grades machines to customers, with the most rational price, most durable performance, and the shortest lead time, with flexible way of supply chain management: Make to Order, or Assembly to Order, or Engineering to Order.
WIP (Work in Process) Flipping and Transfer
Material flow among work stations defines basic difference between Automatic and Semi-Automatic production line:
Layout of Wuxi JACK typical automatic H Beam Welding Production Line:
1) Here, “Semi-Automatic” only refers to its ways of material flow among work stations in production line is implemented manually: Usually by means of travel crane. This is challenge on operators, in terms of operation safety and convenience;
a) Meanwhile, most majority H Beam Machine in semi-automatic line work automatically;
b) The exception is CO2 tack welding in H Beam assembly: When fitting up H Beam with web height higher than 2,000mm, for example, 2,500mm height H Beam, manual CO2 welding is more practical than automatic tack welding;
c) Because for such large H Beam, its flange and web thickness are usually higher than 60mm, which should be paid special attention by operator on small current CO2 welding, to make sure fully fusion welding seam;
d) This is the case with Wuxi JACK Z30 H Beam Assembly Machine for an Iraq customer in year 2026: Customer plans on manual CO2 stitch welding, on their 3,000mm web height and 80mm flange thickness H Beam;
a) Unlike in automatic line, which adopts with 4 sets of trolley column boom structure to forming into a streamline, in semi-automatic line, H Beam SAW Welding Machine is gantry frame structure, welding on 2 pieces of H Beam at the same time;
b) H Beam is laid onto stationary triangular racks during SAW welding, which are usually prepared by customers to save logistics cost. Because these racks are large and heavy, and easy to produce;
c) Double Productivity: Sometimes, customers ask on 2 sets of gantry frame machine being installed in a row, to double productivity. This embodies on flexibility of semi-automatic H Beam Welding Production Line:
