MP25 model Plate Butt Welding Joint Machine in the attached first photo was taken from its butt welding side, or finished workpiece going out side.
Technical Feature: MP series machine adopts welding technology of Melt thru, which means “Single side welding and double side forming”. It has technical specialty of large welding current and forced welding seam formation, with advantage of little deformation and good quality:
Overhead view on melt thru butt welding, in Wuxi JACK machine: (Fig.1)
a) Advantages: Benefiting from this melt thru technique, MP series Plate Butt Weld Joining Machine doubles productivity of plate butt joint welding operation, making sure the entire operation simple and smooth: Without this machine, the butt joint welding on two pieces of metal plates involves:
- 2 times of welding on both sides of the sheet metal plates;
- Plus one time of half finished joint plate overturning;
- Together with carbon arc gouging on the 2nd side of plate;
b) Efficiency Raise from Single Side Welding Only: Now, with Wuxi JACK MP series Plate Butt Welding Joint Machine, only top side plate welding can attain on the target of perfect plate joint, and all the remaining jobs of above mentioned are not necessary any more. In this sense, the total cycle time on plate butt joint can be decreased 30%~ 40%;
Besides, without necessity of flipping the large and heavy carbon steel plate upside down, which entails cooperation among several operators, and should take great care in the process, lesser manpower is needed, the most dangerous step of operation is removed, the entire butt joint welding working process in the MP series machine becomes fully automatic and safe.
a) The first piece of metal plate is hoisted onto input conveyor of the machine, and goes forward toward machine gantry, until its rear edge (The edge for butt welding in the first plate) arrives at position of flame triple cutting torch;
b) By this time, operator should press the STOP button to stop moving forward of the first piece of plate, and have flame triple cutting on the plate, for beveling purpose. The flame triple cutting torch can be adjusted up and down (Motor drive), forward and backward (Manual control), making sure the flame triple cutting torch tip direct at edge of the plate all the while;
c) Please check attached video on triple cutting step in Wuxi JACK MP series Plate Butt Welding Joining Machine. It is same as Plate Triple Cutting Machine. At the completion of rear edge beveling on the first plate, it resumes going forward, until arrives at the welding torch position at the other side of the machine gantry:

a) The second piece of sheet metal plate is hoisted onto input conveyor of the machine, and sent forward, until its front edge (The edge for butt welding in the second plate) arrives at position of flame triple cutting torch;
b) The same beveling step is repeated in the second piece of plate. At completion, it is also sent forward to butt welding base of the machine. By this time, the two pieces of metal plates for butt joint are all right at copper pads unit (Butt welding unit);
a) The attached 3rd~ 6th photos reflect on melt thru butt welding in Wuxi JACK machine. The edges of two plates for joint should be right at middle of copper pads, as can be identified in the 4th photo;
b) During welding operation in the machine, parameters such as welding current/ voltage/ velocity can be adjusted with control console of SAW power supply, as can be found in the 5th photo:

c) Welding Position for Plate Butt Joint: In Wuxi JACK MP series Plate Butt Joint Machine, welding position is 0° flat butt welding, different from 45° fillet welding in H Beam Submerged Arc Welding Machine, or flat fillet welding in H Beam Fabrication Machine. The entire melt thru SAW butt welding is automatically performed.
