China Wheel Type Welder Welding Machine for Strip Production

Welder
Equipment component
According to the direction from the entrance to the exit, the components of the welder are as follows:
1)entry Single channel four-point centering looping table
2)main equipment of welder
3)exit strip four-point centering looping table
driving device side is provided with:
4)entry guide box of cutting scrap and scrap box
5)pneumatic system(the welder has its own air storage tank)
6)cooling water system
the main equipment is equipped with:
7)lubrication system
8)electric control system
2.3 Main Technical Parameters of Welder
1)welder type:C-frame type, double shear in the machine
2) Welding method: single phase DC, narrow overlap, mash resistance seam welding
3)Welding ability: meet the supplied materials conditions listed in appendix 1
4)Welding direction: vertical to the center of the line , from the operation side to the driving side
5)Height of strip path of welder: 1100mm(refer to appendix 8)
6)deviation for joining strip:
a.welding thickness rate(max)
A/B=1/1.5
A: thin strip thickness
B: thick strip thickness
If the welding thickness rate is more than this rate, then should take or add transition steel production of steel coils to achieve this rate.
7)seam quality and welding time
refer to appendix 7
8)clearance when the strip going through the welder
from the width direction: 1550mm
from the height direction:as follow
9)welding overlapping
Overlapping(OS) 1-5.0mm(Automatic adjust)
Overlapping(DS) 1-5.0mm(Automatic adjust)
10)welding speed 5~9 m/min
