MP40 High Quality Plate Butt Joining Machine for Plate Join

Feature and Application of MP40 Plate Butt Joint Welding Machine:

1) MP40 High Quality Plate Butt Joint Welding Machine is large sized model in its product group；

2) In the attached first photo, operators were grinding the welding seams for removing welding reinforcement of the finished jointed plate fabricated from the Wuxi JACK MP40 plate Flat Butt Welding Machine.

1.  Application of MP40 Plate Flat Butt Welding Machine:

1) Usage, Specification and Core Technique in MP40 Plate Butt Welding Machine:

a) Function: This Plate Butt Joint Machine is for joint 2 pieces of metal plates with its width up to 4000mm, in the form of automatic large current SAW butt welding and or gas shield butt welding, on single side of the 2 metal plates;

b) Melt-Thru Welding: With adoption of melt through technology, got its welding seam formed on both sides of the steel plates. In other words, single face welding double face completion;

2) Where Used: In many infrastructure projects, such as Railway Bridge/ Highway Bridge/ Bay Bridge, huge size of steel plates need to be used as raw material of construction, which should be got from large size MP40, MP45 or even MP50 Plate Flat Joint Welding Machine.

2. Technical Characteristics of MP Series Plate Butt Joint Machine:

1)  Welding Groove Cutting in Plate Flat Butt Welding Machine:

a) Challenge and Critical Control Point: Of all the welding positions in machine works, flat butt welding is difficult for satisfactory seam formation, compared with, for example, 45° fillet welding in LHA/LHC/LHT H Beam SAW Machine, or flat fillet welding in H Beam Fabrication Machine. So, it usually needs to have two sides of welding, especially for joint metal plates with thick thickness and large size in Plate Butt Joint Welding Machine;

b) For this reason, In melt through technology of MP Plate Flat Butt Welding Machine, welding groove needs to be made ahead of time;

2) There are 2 options for getting this purpose in the Plate Flat Joint Welding Machine: 

a) Either customer can make the bevel by means of an Edge Milling Machine;

b) Or ask for optional triple torch equipped on the MP series Plate Butt Joint Welding Machine, as shown in the attached 2^nd photo. It is flame cutting with A.C. inverter control speed, to make beveling on the edge of plates into required chamfer (U/V/X);

3) Input and Output Conveyors in the Plate Flat Butt Welding Machine:

a) Length: The conveyors have standard length of 9m for feed in and 15m for send out in MP40 Plate Butt Joint Welding Machine. And special length of the conveyors is available based on designated length of raw material from customers;

b) Driving Segment:  For standard length of conveyors in the Plate Butt Welding Machine, there is one motor drive segment at input conveyor, and two motor drive segments at output conveyor respectively;

c) Alignment for Linearity:  Holding wheels and plate pushing units are equipped on the input and output conveyors of the MP series plate Flat Butt Welding Machine, ensuring lengthways linearity of the plate during joining;

d) Sometimes customer may need more than 2 pieces of plate joint together in the Plate Butt Welding Machine: The attached 3^rd plate jointed with the joint plates, and output conveyor should be lengthened accordingly;

4) Critical Points for Successful Running of Melt through Technology in MP Series Plate Butt Joint Machine:

a)  The attached 3^rd photo shows butt welding quality in MP Plate Butt Joint Welding Machine. The 4^th and 5^th photos show close up of the weld torch;

b)  You can see besides motor for driving the torch up and down/ Wire feeding unit/ Flux conveying tube, there are wire straightening unit for keeping linearity of welding wire, screw type adjusting unit for managing pressing force of wire feeder;

c) All these are critical points for maintaining successful running of melt through technology in MP series Plate Flat Joint Welding Machine. Please check attached video on SAW butt welding in the plate Flat Butt Welding Machine.
