Parameters set up in Flat Butt Welding Machine: (Fig.6)
C. General Steps in Operating the Plate Flat Butt Welder:
In a nutshell, for delivering satisfactory joint plate from the Plate Flat Joint Butt Welding Machine, you need to complete the basic steps of:
1. Material Handling in Plate Butt Joint Welding Machine:
This includes:
1) Loading on two pieces of metal plates onto input conveyor of Flat Butt Welder;
2) Loading finished joint plate off output conveyor;
2. Alignment on Metal Plates in Flat Butt Welding Machine:
1) This is critical for guaranteeing eligible melt thru welding quality in the Flat Butt Welding Machine;
2) It includes aligning two pieces of metal plates along its length direction, so that lateral side of the two metal plates are collinear;
3) And aligning width side of metal plates, for joint against centerline of copper pads in the Plate Butt Joint Welding Machine;
3. Flame Triple Cutting Process: Properly setting pressure/ flame of Oxygen and cutting gas, and angle of triple cutting torches;
4. Melt thru Welding: This is “Core of the core” in operating the Flat Butt Welding Machine: Welding current/ welding voltage/ wire feeding speed.
D. Tips on Operating Plate Butt Joint Welding Machine:
1. Preparation Work for Running Plate Flat Joint Butt Welding Machine:
1) Operator should be familiar with all the buttons/ selection switches of Plate Flat Joint Butt Welding Machine;
2) Make sure all the components/ Subassemblies of the Flat Butt Welder are in normal state for running;
3) Modulate process parameters of triple cutting/ butt welding in the Plate Butt Joint Welding Machine;
4) Switch on supply of preheating oxygen/ cutting oxygen/ acetylene or propane and adjust its pressure based on thickness and chamfer type of the workpieces in Plate Butt Joint Welding Machine:
a) 0.5 ~ 1.0 MPa for preheating oxygen;
b) 1.0~ 1.2 MPa for cutting oxygen;
c) 0.25 MPa for Acetylene;
5) Start on water cooling system for copper pads, and adjust water pressure (0.2~0.4 MPa);
2. Material Handling in Flat Butt Welding Machine:
1) Logic Interlock: To fully make sure safety operation on the Flat Butt Welder, and best quality delivered, in control system of Plate Flat Joint Butt Welding Machine, there are interlock logic between input and output conveyors and function units;
2) For example, when the working mode selection switch is at “Cutting” or “Welding”, managing input and output conveyors is invalid;
3) Operator should understand and follow these logics for proper handling and position control on plates;
3. Flame Triple Cutting Technology in Plate Flat Joint Butt Welding Machine:
1) Based on thickness of metal plates, triple cutting in the Flat Butt Welder can be divided into two broad groups of (thinner than 28mm) and (between 28mm and 40mm) of metal plates;
2) We give detailed instruction on pressure and flames adjustment in manual book of the Plate Butt Joint Welding Machine;
4. Melt Thru Welding in the Flat Butt Welding Machine:
1) Two layers of dedicated welding flux need to be deposited on the copper pads, and on the workpieces respectively;
2) Two layers welding flux are of different grade, which we give recommendation based on accumulated empirical data and years of experience on Flat Butt Welder, which varies on material and thickness of metal plates;
3) Also, we will give a rule of thumb on suggested key process parameters including Butt Joint clearance/ Welding current/ Welding Voltage/ Wire feeding speed in manual book of the Plate Butt Joint Welding Machine.
E. Summary on Wuxi JACK Flat Butt Welding Machine:
1. Operation of MP series Plate Butt Joint Welding Machine involves series of skill/ technique/ experience on machine itself and process technology;
2. Ss leading producer of Flat Butt Welder, Wuxi JACK is willing to share technical know-hows to customers worldwide who have demand and interest on it.
