Water Cool SAW MP20 Plate Butt Welding Joint Machine

1. What is the Position of MP20 Plate Butt Joint Weld Machine in Value Chain?

1) Mechanical Structure: MP20 model Plate Joint Welding Machine has split type main body, as shown in the first photo, which was taken at Wuxi JACK assembly workshop:

Check from lateral side, the machine main frame has two independant parts: Higher gantry and lower welding worktable: (Fig.1)

2) Function and Specification: MP20 model machine produces raw materials for manufacturing facilities: Integral piece of longer and or wider metal plates. The biggest width of original plate for joint is 2,000mm:

The joint larger plate, butt welded from original 2 pieces of smaller ones from Wuxi JACK MP20 model machine: (Fig.2)

3) Related Machine: Plate Butt Joint Welding Machine is reverse equipment of Strip Plate Cutting Machine, which cut metal plate into narrow strip metal plate. With these two types of equipment, you can get any size of metal plate for your necessity.

2.  Working Principle of MP Series Plate Joint Welding Machine:

1) Central Welding Technique: MP series Plate Flat Butt Welding Machine joint sheet metal plates in the welding mode of melt thru welding -- Single side welding and double side forming. The working principle is to butt weld the 2 pieces of sheet metal plate with large current --- For SAW (Submerged arc welding), specification of welding power supply is ZD1250, Rated output current of 1250A:

2) Water Cooling for Melt Thru: There is copper pad mechanism for holding sheet metal plates firmly during working of the MP series Plate Butt Joint Machine. These copper pads help force formation of welding seam, and are water cooled in the fully penetrated welding process. Hence the product name of “Water Cool SAW configuration” get from. Please check the attached 2^nd photo on SAW butt welding seam in the equipment:

3. Working Unit Arrangement in MP20 Plate Butt Joint Machine:

1) Fully Penetration Welding Work Table of Plate Joint Welding Machine:

a)  Welding work table of the machine has solid base, as shown in the attached first photo. The clear view on V slot on its top section, which is used for implementing on melt thru welding, please see the attached 3^rd photo and below. The above mentioned copper pad is located at bottom of the V slot. You can identify there are row of pressing blocks on its above, with a clearance for pushing in and clamping of workpiece (Metal plates for joint):

2) Gantry Platform in Sheet Metal Plate Butt Joint Welding Machine:

a) Mechanical gantry platform right behind the welding work table has broad breadth on its top, which is for holding welding power supply/ SAW welding flux recycling machine/ welding torch group of the Plate Joint Welding Machine at welding side, and triple cutting system at the other side of the gantry:

b) Welding Groove Prepare: The flame triple cutting torch and its working process please check the 4^th and 5^th photos, and attached video. This is optional configuration in MP series Plate Butt Joint Machine, for cutting out U/  V/  X types beveling on edges of thick plates before butt welding, to get broader and deeper welding fusion, and fully penetration welding. It works in the same way as Triple Flame Cutting Machine; The other kind of equipment with mechanical way of making beveling is Hobbing Cutter:

3) Operating Panel and Cable Arrangement in the Plate Butt Joint Machine:

a) Power cables and control cables in the Plate Butt Joint Machine are applied by way of drag chain, and junction boxes at the lateral side of gantry beam;

b) Operating panel is integrated onto top cover of electric control board, which is put alongside gantry body of the machine;

c) Black color grounding cable: Please check the 6^th photo.
