Shown in the above photos, successful daily operation of the machine involves below six necessary steps for prepare:
1. H Beam Holding Racks of I H Beam Gantry Welding Machine:
1) To save cost for customers, these brackets usually are prepared by customers, according to prints from producer Wuxi JACK;
2) Each of these brackets are 2 triangulars, one large and one small, facing each other, forming into a 45° included angle, with stiffeners inside the 2 triangulars, and connected into an integral unit
3) These brackets should be positioned and fixed on a row in accurate alignment during installation stage, and tested its linearity during commissioning;
4) For the two branches of LHA model machine: LHAZ center operating and LHAC side operating, orientation of triangular racks are different;
5) These brackets should be made clear ahead of time installation;
2. Installing Guiding Rails of I H Beam Welding Machine:
This should be completed with precise parallelism and correct span:
1) This is the precondition to guarantee stable precise longitudinal movement of machine main frame, during the entire welding operation;
2) There are corresponding technical tolerance stipulated in machine specifications;
3. Reasonably Arranging Welding Supplementary Function Units of I H Beam Submerged Arc Welding Machine:
This machine has fairly amount of welding supporting mechanisms, that one set of the machine has 2 groups (LHA series and LHT model) or 1 group (LHC model) of every specie function cells, including:
1) Submerged arc welding machines and its control console, for tandem arc SAW welding, control console combines both D.C. and A.C. welding power supplies;
2) Welding wire feeding and straining unit;
3) Welding flux feeding and reuse unit;
4) Welding seam tracker;
4. Well Planned Workshop Utility for Running I H Beam Welding Machine:
1) Power Grid: Workshop for installation large current SAW welding machine should have sufficient electricity capacity. Including: Electricity power, machine and welding power supply cables, cable hanging racks, etc.;
2) For example, for the special design large LHC model in June 2025 year, one set of the machine should be prepared with electric capacity of:
a) LHC model machine itself, 5kW, 25A;
b) ZD7-1600 D.C. SAW welding machine, 84kW，160A;
c) ZDE7-1200 A.C. SAW welding machine, 71kW，150A
3) Voltage Regulator: Stable power grid without fluctuation directly affects performance of SAW power supply, and hence welding quality;
5. Security Measures and Cells in Wuxi JACK I H Beam Welding Machine:
These are assistant but indispensable units for daily running of machine operation. You may overlook it normally, but can not do without it. For example:
1) Climbing staircase at lateral of machine main frame. Mechanical main frame of some models machine is as high as 4,000mm. So, proper installed climbing ladder and surrounding fence is of vital importance for making sure safety of operators;
2) Guarding fence surrounding platform;
3) Alarm light;
6. Careful Material Flow Plan on Operating H Beam Welding Machine:
This includes:
1) Raw materials assembled H Beam coming in;
2) Finished workpiece SAW welded H Beam sent out;
3) Internal hoist and flipping H Beam by means of traveling crane, in the case of single equipment LHA or LHT model;
4) Locating machine control board, SAW welding machines, SAW welding flux reuse machine, this is especially important for LHC model, which has column structure, prone for imbalance, if not planned carefully.
