MP20 Automatic Plate Butt Joining Machine with Triple Cutting

The automatic MP20 Plate Butt Welding Machine in the attached first photo was taken at Wuxi JACK workshop, for being commissioned before delivery to customer.

1. Application of MP20 Plate Butt Joint Welding Machine:

1) Function and Specification:  MP20 plate Flat Butt Welder is the smallest, also one of the most frequent selected models of MP series Plate Butt Weld Joining Machine. This model of plate Flat Butt Welder is for fulfiling butt joint metal plates of up to 2,000mm wide, which is the common size of the steel plates, with the optional function of triple cutting on the plate，for the purpose of plate beveling before butt welding. The usage of beveling is to get optimum fusion quality of butt welding seam;

2) One Machine Two Functions:  Without this optional unit of triple flame cutting, customer need to specifically make bevel on the edge of the plates at other equipment ahead of time operating on the Plate Butt Joint Welding Machine. Usually this is acquired by Edge Milling Machine. With triple cutting, one set of MP series Plate Butt Weld Joining Machine completes the function of both beveling and joint butt welding with one set of the Plate Butt Joint Welding Machine, which is a cost effective way of plate butt joint solution for customers.

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

1) The general structure and working principle of MP series Plate Butt Welding Machine is something similar to Edge Rounding Machine: A fixed main body with front feeding-in and rear sending conveyor. Raw material goes through the plate Flat Butt Welder, and turned into finished product;

2) Workpiece Going Through: The plate feed in side of the gantry side of Plate Butt Welding Machine is installed with triple cutting unit (The attached 2^nd photo), the opposite side (send out) side of the gantry is installed with welding torch unit (The attached 3^rd photo);

3) Melt Thru Butt Welding Unit of Wuxi JACK MP series Flat Butt Welder:

a) The most prominent technical feature is MP series Plate Butt Joint Welding Machine is Melt through Technology (One side welding Two side forming). Under majority conditions the butt welding mode is SAW (Submerged arc welding), for joint metal plates with thickness 6~40mm. In minority conditions, for joint thin metal plates (2~6mm), CO₂ gas shielded welding is used. This is very similar to welding mode distribution in H Beam Fabrication Machine. The attached 3^rd photo and attached video show CO₂ gas shielded welding in MP series Plate Butt Weld Joining Machine;

b) Please check the attached 3^rd and 4^th photos. In MP series Plate Butt Welding Machine, melt through technology butt welding system include one set of welding power supply equipped with operating console, welding torch and its motor drive carriage along horizontal guiderail of main body, welding torch lifting unit, welding torch cross-slides, welding flux recovery unit (SAW only), wire feeding and straightening mechanism;

4) Copper Pads of the MP Series Plate Flat Butt Welder: 

a) Function:  Please check the attached 5^th photo. This unit is installed beneath the workpiece, and worked in the form of upward stroke during start up operation of the Plate Butt Welding Joint Machine. Which means, it pressed the plates tightly against its bottom surface of the joint plates;

b) Usage: It is for forcing formation of “One side welding Two side forming” (Melt through Technology) butt weld seam in the MP series Plate Butt Welding Machine;

c)  In MP series Plate Butt Weld Joining Machine,  this copper pad unit is water cooled;

5) Copper Pads Elevating unit of the MP Series Plate Flat Butt Welder:

It is motor drive and for manipulating the above mentioned copper pads along vertical direction;

6) Water Cooling System of the MP Series Plate Flat Butt Welder:

a)  This water cooling unit is for heat dissipation of the above mentioned copper pads during butt welding process in the Plate Butt Weld Joining Machine;

b)  It utilizes circulating water. There is a water tank alongside the mechanical main body of the Plate Butt Joint Welding Machine;

7)  Hydraulic System of the MP Series Plate Flat Butt Welder:

It is for driving the item three sets of downward pressing unit of this Plate Butt Joint Welding Machine;

8) Electric Control system of the MP series plate Flat Butt Welder: 2 pieces of A.C. Inverter and other elements: Contactors, relays, fuses, breakers, etc.
