MP35 Melt Through Cost Effective Plate Joint Welding Machine

Operation View on Plate Butt Welding Joining Machine:

The vertical view on a set of Wuxi JACK produced and exported to Russia MP35 model Plate Butt Joint Welding Machine, in the attached first photo demonstrates on typical working site of the equipment: The raw materials (Metal plates for joint) next to conveyor, and completed joint plate on the output conveyor roller table:

Typical working site and finished workpiece of MP35 model machine: (Fig.1)

1. Copper Pad and its Cooling Water Circulation for Melt thru Technology of MP Series Plate Butt Welding Joint Machine:

1) Finished Welding Seam on Joint Plate: You can find the welding seam formed on the joint plate at the right most of the first photo, and local amplification in the attached second photo and below. MP series plate Flat Butt Welding Machine adopts with Wuxi JACK patent melt thru technology in its SAW butt welding process, delivering high level of welding seam on both sides of the joint plate, with single side welding. This raises welding efficiency to the original twofold level:

Finished joint welding seam on joint plates: (Fig.2)

2) The attached 3^rd photo shows arrangement of copper pad before its installation into the Plate Butt Welding Joint Machine. For successful completion of melt thru (Fully penetration welding), especially for medium and large size plates, copper pads and its water cooled unit are critical for finishing the job:

3) Melt thru Come into Being in Wuxi JACK MP Series Plate Butt Welding Joint Machine:

a) SAW Welding Flux: Before melt thru butt welding in the machine, a thin layer of sintered welding flux should be deposited on the surface of copper pad; 

b) Plates Clamp: And the two pieces of sheet metal plates are pressed tightly on the copper pads, with another large amount of welding flux deposited on the welding seam, please check attached video and the attached 4^th photo:

Firmly clamping the 2 pieces of plate with blocks, which are driven with hydraulic cylinders: (Fig.4)

 c) Melt Thru Welding: The large current SAW (Submerged arc welding) and copper pads help realizing fully penetration welding seam coming into being in the machine, attaining the purpose of melt thru;

4) Water Cooling of Copper Pads  in Plate Butt Joint Welding Machine:

a) Why Need Water Cooling: In MP series machine, the SAW butt welding has large current, which generates on fairly quantity of heat, and may have negative effect on the copper pads and welding perforamnce. Correspondingly, there are circulating cooling water system, for effectively cooling these copper pads during work of the Plate Butt Welding Joining Machine;

b) Working Principle: As can be seen from the attached 3^rd photo, operator was connecting these coppers pad with a blue color rubber hose. During large current SAW butt welding, cooling water run through this rubber hose, taking heat away from the copper pads. A large water tank is located at function area of the machine together with hydraulic pump system, completing the entire water cooling system for copper pads:

Large capacity cooling water tank equipped with MP model machine: (Fig.5)

5) Copper Pads Elevation in Sheet Metal Plate Butt Welding Joining Machine:

a) Working Way: The copper pads are elevated integrally under motor drive;

 b) It descends down during in feed and out send of the plates into and out of the machine, and ascends up at the positioning of the plates, and then is pressed firmly against bottom surface of the welding seam;

c) The up and down stroke of copper pads is controlled with photo-electric switch in the control system of machine.

2.  Meaning of “Cost Effective” in Operation of Plate Butt Joint Welding Machine:

One Machine Double Functions: This machine with core technology of Wuxi JACK patent, incorporates cutting and welding function into one equipment, and doubles productivity on plates joint by means of:

1) Flame Triple Cutting: Integrate beveling function by means of Oxygen fuel triple cutting torch, as shown in the 5^th photo and below. Without it, beveling on plate thicker than 15mm need to realized with XBJ series Edge Milling Machine, or CNC-CG series Triple Plate Cutting Machine; Or, without beveling for making welding groove, the max. thickness for butt welding is only 15mm, instead of 40mm for standard specification:

Oxygen fuel flame trip cutting torch mechanism, as critical assitant function unit of Plate Butt Joint Welding Machine, especially workpiece is large size plate thicker than 15mm: (Fig.6)

2) Remove the second welding step on the opposing side of the plates and hence dangerous and toilful work of metal plates flipping;

3)  Remove carbon gouging job which is necessary before the second side welding;

In all, any 2 pieces of rough metal plates can be joint together with one time passing through Wuxi JACK MP series machine. This is similar to 3 in 1 H Beam Assembly Welding Straightening Integral Machine, that one set of machine integrates several functions into one set of powerful equipment.
