MP20 To MP50 Sheet Metal Steel Plate Butt Joint Welding Machine

A. Usage and Great Value of MP20 to MP50 Metal Steel Plate Butt Joint Welding Machine:

1. Usage: MP series Metal Steel Plate Butt Welding Machine joins 2 pieces of sheet steel into an integral piece of larger length, with strength of joint seam more stronger than base metal:

2. Specification: Based on length of joint welding seam, in other words, width of plates for butt welding, the model of machine can be from MP20 up to MP50, which corresponds with the Max. 2,000mm to 5,000mm seam length respectively:

A piece of finished joint plate of 2,000mm width and 30,000mm length, being laid on output conveyor roller table of Wuxi JACK MP25 model Metal Steel Plate Butt Welding Machine: (Fig.1)

3. The material of Metal Steel Plate for butt welding can be any common seen type: Carbon steels of different grades, including Chinese grade Q235/ Q345, Stainless Steel, Al;

4. Welding Mode: SAW (Submerged arc welding) for 6~ 40mm thick carbon steel plate, and GMAW CO₂ welding for 5~ 6mm sheet metal;

5. Application Scenario of Metal Steel Plate Flat Joint Butt Welding Machine:

1) Large Pipe Fabrication: When making production on large diameter pipe (Φ5,000mm diameter and above), single piece of steel plate length is not long enough to be bent and rolled into a full circle of Φ5,000mm diameter and above. By this time, it is necessary to joint 2 pieces of steel plate with this MP series Metal Steel Plate Butt Welding Machine;

2) Hoist Crane Production: The large dimension hoist cranes involves consumption of long length steel plate, which need to be acquired from butt welding on steel plates from Steel Mills;

6. Benefit on Productivity, Variable Cost, and Safe Operation with Metal Steel Plate Butt Joint Welding Machine:

1) Benefiting from this Wuxi JACK patent technology melt thru technique on butt welding, which implicates “Single side welding, and both sides of plate with seam formation”, MP series machine doubles productivity of plate butt joint welding operation, making the entire operation simple and smooth:

2) Without this machine, the butt joint welding on two pieces of Metal Steel Plates involves below necessary steps:

a) 2 times of welding on both sides of Metal Steel Plates;

b) One time of half finished joint plate overturning, with the help of overhead traveling crane;

c) Carbon arc gouging on the 2^nd side of plate;

3) Now, with Wuxi JACK MP series Metal Steel Plate Butt Joint Welding Machine, only top side plate welding can attain the target of plate joint, and all the remaining jobs of above mentioned are removed, the total cycle time can be decreased 30%~ 40%;

2) Safe Operation and Lesser Operator: Besides, without necessity of flipping the large and heavy steel plates 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 operation on plate joining, with MP model Metal Steel Plate Butt Joint Welding Machine, becomes fully automatic and safe.

B. Main Function Units in MP Series Metal Steel Plate Flat Joint Butt Welding Machine:

1. General Layout of MP Model Metal Steel Plate Butt Welding Machine:

a)  Running site of Wuxi JACK MP20 model at customer facility: (Fig.2)

b) Design print on Wuxi JACK MP20 to MP50 models machines: (Fig.3)

1) Plates Flow: Checking on the above photo and drawing, you can find in the sequence of material flow from input conveyor to output conveyor:

2) At incoming side of machine gantry, there is flame triple cutting torch, and at the outlet side of the gantry, there is melt-thru butt welding torch system;

2. Flame Triple Cutting Torch in Metal Steel Plate Flat Joint Butt Welding Machine:

1) Task: This unit can be viewed as a set of Plate Triple Flame Cutting Machine. It is for cutting out welding groove on the edges of Metal Steel Plates, when plates thickness for joining is above 15mm, so as to guarantee fully penetration on joint seams, in subsequent butt welding:

a) Oxygen fuel triple cutting, before butt welding: (Fig.4)

b) Flame triple flame cutting, at plate incoming side of machine gantry: (Fig.5)

c) Finished flame triple cutting plate, for butt welding: (Fig.6)

2) This flame triple cutting unit is optional configuration for MP models machines. Without it, customer need to prepare specific equipment for cutting welding groove on edges of Metal Steel Plates, such as XBJ series Edge Milling Machine;

3. SAW Butt Welding System in Metal Steel Plate Butt Welding Machine:

1) Welding Technology: The attached photos also reflect on machine central working unit: SAW butt welding system. The critical technical know how is Melt Through, the precondition on fulfilling high quality and efficiency butt welding effect:

2) Welding Torch Installation in Wuxi JACK Metal Steel Plate Flat Joint Butt Welding Machine: (Fig.8)

Shown in the above photo, this includes:

a) Welding torch and its high precision positioning mechanism;

b) Motor drive welding torch lifting mechanism;

c) Welding wire feeding unit and tube;

d) Welding wire straightening unit;

e) SAW welding flux conveying and recycling unit: Sending and recovering tubes; Yellow color flux hopper; Grey color Welding flux recycling machine;

4. Copper Pad and Welding Base of Metal Steel Plate Flat Joint Butt Welding Machine:

1) The butt welding bed which is assembled with an array of copper pads: (Fig.9)

a) Arrangement: You can see there are numerous pairs of black color holding blocks just above the copper pads, which have interval space of 300~ 350mm;

b) The quantity of black color holding blocks depends on length of welding table, equals to length of butt welding seam: In the total welding seam width of 2000mm of MP20 model, it needs 6 pairs of such holding blocks;

c) Function: These holding blocks are for the purpose of pressing the two pieces of Metal Steel Plates firmly during melt through butting welding operation, which are driven with oil cylinders to deliver heavy force. The oil cylinders are installed inside the trapezoidal cover, at both sides of the copper pads and welding base:

d) The oil cylinders being installed, inside the trapezoidal cover of Wuxi JACK MP30 model metal Steel Plate Butt Welding Machine worktable: (Fig.10)

2) Reliable Earthing: There are black color earthing cables, connected with each of the holding block, guaranteeing safe operation of Metal Steel Plate butt joint welding operation:
