1. the fiber laser core diameter:50um

2. Wire length :10M

3.The stable output power:+-1.5%

4.BPP<1.5

5.Half angle diverges:0.06 microradian

 Choose correct protection gas.

1.use  argon gas,the fluent:15-25L/min,use flowmeter.

How to find the focus

1.use aluminum alloy bead welding(power adjust less than 1000w),adjust the height until sparks to MAX.

How to set the swing parameter:

1.choose frequency 100-300HZ,swing filed1.0-1.5 mm(a little bigger than the wire diameter)

0.1d=v/f

πd=v2/f

V1 is the welding speed,V2 is the swing speed

normally V1=20mm/s ;d=1.0mm

f=200HZ,v2=628mm/s

How to set the parameter of wire

wire diameter:1.0-1.2mm

feeding wire speed1.0m/min

Vw=KVg

Vw=Vfπd2/4 

Vg=VwHw

V w is the wire V.

Vg is the gap of interval

K is formal parameter(1.1-1.7)

V1 is feeding wire speed

Vw is welding speed

H is thickness of plate

d is the diameter of wire

W  is the width of interval

The core diameter is smaller ,the welding depth is big
