a) A piece of 30m long integral steel plate being joint from 2 pieces of 15m long plates, in Wuxi JACK MP20 model machine: (Fig.1)

b) The finished joint plate, being laid on output conveyor roller table of Wuxi JACK MP20 model machine: (Fig.2)

3. Workpieces Suitable in Wuxi JACK MP Models Steel Plate Flat Butt Welding Machine:

1) Plate Thickness for Butt Welding: This machine is for fulfilling flat butt joint on metal steel plates with various thickness, especially carbon steel: From the minimum thickness of 1 ~ 6mm, to larger thickness of 6 ~ 40mm, or even thicker;

Finished butt joint steel plates and welding seams, acquired from different models of Wuxi JACK Steel Plate Flat Butt Welder machine: (Fig.3, 4)

2) Plate Width for Butt Welding: The max. width of steel plates for butt joint in this machine, can be any size within the range of 2,000 mm~ 5,000 mm. This is the Max. length of butt welding worktable, and hence length of butt welding seam from MP models machine. When butt joint width greater than 5,000mm, rigidity of welding table can not be guaranteed, which we do not recommend for customers:

4. Application of MP Series Sheet Metal Steel Plate Butt Joining Welding Machine:

1) Task: This machine fulfils butt welding on 2 pieces of metal plates, material: carbon steel/ stainless steel/ Al, by means of butt welding;

2) The Related Equipment include:

a) RH series Edge Rounding Machine;

b) J series Stiffener Plate Straightening Machine,

Which are used for manufacturing on large machinery;

3) Applied Industries:

Together with MP series Plate Butt Welding Machine, these machineries can be formed up various production line for Shipbuilding / Port Machinery, and Bridge Construction, Hoisting Crane Machinery /Steel structure/ Tank Welding, etc., which have common points of large size steel plate being consumed as its raw material;

4) Besides, MP series machine can also be applied as individual equipment under any special case.

B. Technical Superiority of Wuxi JACK MP Series Steel Plate Flat Butt Welding Machine:

1. Wuxi JACK Patent Technology of Melt-Thru: In 2016 Wuxi JACK engineering team got the patent on core technology, which is applied in MP series Steel Plate Flat Butt Welding Machine --- Melt Thru welding, which means: Single side welding and double sides welding seam formation:

Melt thru SAW welding, being carried out in Wuxi JACK MP series machine, on steel plate butt joint welding: (Fig.6, 7)

2. Welding Technique Adopted in Wuxi JACK MP Series Sheet Metal Steel Plate Flat Butt Welder Machine:

1) Outline: As an efficient automatic equipment on plate butt welding, MP series machine was developed by Wuxi JACK engineering team, on the basis of advanced technique;

2) Multiple Welding Modes Options on the Basis of Plate Thickness:

Based on material and thickness range of plate for butt welding, the adopted welding technique can be:

a) GMAW CO₂ welding for welding on thin plates, thickness in the scope of 3 ~ 10mm:

Trial run on CO₂ gas shielded butt welding on thin steel plate: (Fig.8)

b) SAW Submerged Arc Welding for welding on thick plates, thickness in the scope of 6 ~ 40mm;

c) Plasma welding on small thickness (3~ 12mm) ferrous and non-ferrous steel: Stainless steel/ Al/ Low carbon steel:

With advantages of little deformation/ convenient and safe operation/ As well as good quality;

3. One Machine with Two Functions in Wuxi JACK Sheet Metal Steel Plate Butt Joint Welding Machine:

1) Necessary on Plate Edge Milling: When plate thickness exceeds 15mm, to get full penetration of welding seam from melt-thru welding, edge of steel plate need to be beveled before melt-thru welding;

2) Edge Beveling Way: This can be acquired:

a) Either with XBJ series Edge Milling Machine,

b) Or CNC-CG model Triple Flame Cutting Machine;

c) Or, in MP series machine, its steel plates coming in side will be equipped with triple flame cutting unit:

a) Oxygen fuel triple cutting unit, at incoming side of Wuxi JACK Steel Plate Butt Welding Machine: (Fig.10)

b) Cutting out welding groove by means of flame triple cutting: (Fig.11)

4. User Friendly and Intuitive Operation with HMI, in Wuxi JACK MP Models Steel Plate Butt Welding Machine:

HMI (Human machine interface) is adopted in electric control system of machine. By means of just keying process control parameters on plate butt welding, operator can have a high efficient and eligible management on operation:

1) HMI touch screen integrated with control panel of MP models machine: (Fig.12)

2) Process control parameters on steel plate butt welding, with touch screen of HMI: (Fig.13)

3) Besides, control console of SAW welding power supply, is used to manage on butt welding operation at welding point: (Fig.14)

C. Cost Saving and Production Efficiency Raise Benefitted from Wuxi JACK Steel Plate Flat Butt Welder Machine:

1. Before Using Steel Plate Butt Joint Welding Machine:

The 5 steps for accomplishing on metal steel plate joint operation:

1) The 1^st Step: Implement on the 1^st time welding one side of the 2 pieces of joint steel plates;

2) The 2^nd Step: 180° flip the 2 pieces of half joint plates by means of traveling crane or other logistics equipment;

3) The 3^rd Step: Carry out carbon arc gouging on the 2 pieces of half joint plates;

4) The 4^th Step: Carry out the 2^nd time welding on the opposing side of the 2 pieces of half joint plate;

5) The 5^th Step: Carry out carbon arc gouging on the finished joint plates;

2. With Put Into Use on Wuxi JACK MP Models Steel Plate Butt Welding Machine:

1) Productivity Raise: Now, with advanced technique of Melt Thru (Single side welding and double side forming), by operating on MP series machine, the above listed 2^nd to the 5^th steps are removed, raising working efficiency on plate butt joint around 30%~ 40%;

2) Operator Reduced: The original necessary 2 operators on plate butt welding, can be reduced to only 1 operator now;

3) Safety Assurance: The safety risk of flipping heavy plates by means of traveling crane can be totally removed, fully guaranteeing on fully operation, benefiting from high level performance of Wuxi JACK MP series machine.

D. Selecting Proper Models of Sheet Metal Steel Plate Butt Joint Welding Machine:

1) Wuxi JACK MP series machine has optional unit of flame triple cutting unit, for cutting out welding groove on edges of the joint plates, before melt thru welding operation;

2) If customers do not choose this flame triple unit in the Flat Butt Welder, the other option on cutting out welding groove on edges of steel plates, before butt welding operation, can be:

a) XBJ series Edge Milling Machine;

b) CNC-CG series Triple Flame Cutting Machine;

2. Conventional Models of MP Series Steel Plate Flat Butt Welding Machine:

1) Based on the Max. plate width, which equals to the max. length of butt welding seam, there are several standard models of MP series machine for customer choice, from MP20 to MP50 models. The related technical parameters of each model are listed in below table;
