In this section we will introduce a gantry frame welding machine designed and produced for a famous overseas welding company of branch in China, which would be used in their welding laboratory for validating SAW (Submerged Arc welding) technique. So, it is a special made welding equipment for special use.
1) This special made gantry welding machine should be capable of making independent running of welding head and its carriage;
2) Welding mode is SAW (Submerged Arc welding);
3) The entire set of special made welding machine should have good stability, high rigidity, flexible and convenient operation;
4) The equipment can work steadily and reliably within the range of 150A~ 1300A within fluctuation tolerance of ±5%;
5) This special made welding machinery should be equipped with workpiece worktable. The worktable is designed and made based on workpiece type.
1) The complete set of special purpose welding machinery is composed of mechanical machine body of gantry frame; SAW power supply, welding console, and wire feeder;
Rated Welding Current | 1000 A |
Rated Duty Cycle | 100% |
Input Electricity Specification | 3P 380V ±10%,50Hz±1Hz |
Output Current | 150 ~ 1300 A |
No Load Voltage | Up to 75V |
i. It is a kind of multi-function welding power supply. It can be used in both submerges arc welding, and open arc welding;
ii. It can be used in various welding equipment, including general purpose and special welding machinery;
iii. Constant voltage and constant current;
iv. Average working life is 15 years in the working mode of 3 shifts;
v. Remote control available, and welding parameter adjustment with console;
a) Precise management of welding technology, arc striking characteristic, welding start and stop, welding seam dimension and appearance, reducing welding cost for both “ordinary” and specialized welding machinery;
b) Productivity is raised thanks to its high deposition rate, high welding speed and eliminating bottleneck;
c) Welding program, wire feeding speed, wire size, welding parameters, and welding mode can be modulated very easily within extensive range. This is especially beneficial for specialized welding equipment;
a) Wire feeding range is 0.4~ 7.4m/min., wire diameter range is ф2.4-ф5.6mm;
b) Wire feeding box reduction ratio is 142:1, and optional 95:1 is available for special welding equipment;
c) Wire feeding is powered with D.C. motor, managing wire feeding speed precisely;
d) Best pressure fitting by means of adjustable spring for clamping welding wire, avoiding wire deformation;
e) Wire feeding head can be revolved in full position, equipped with wire straightener, meeting high demand of all kinds of welding application, including SAW in this special made gantry welding machine;
It is the body and trunk of this special made welding machine. It can be summarized in the form of below parameters:
