5. Welding Procedure
1. Welding position: The welding torch is be positioned in the vertical pipe.
2. Swing welding
1) Before welding, press the button to swinging positioning, observe the location
of the gap are consistent with bevel edge. Usually, leave a gap on both sides of
the cover. In normal, the filling thickness of the gas shielded welding machine is
about 2mm.If covering filling thickness is greater than 2mm, swinging width
should be smaller than the weld width, reducing welding speed in time, pay
attention to adjust the residence time of on both sides of weld bead, avoid to
causing weld slag on both sides.The swing width of the middle filling layer shall
be subject to the width of the fusion line in the groove, and the residence time
on both sides of the groove shall be adjust correctly. In actual welding, the free
transition of the weld pool shall be subject to the guarantee.
2) When the groove clearance of the filling layer is small, the first filling can be
carried out with small swing and small current and voltage.
3) The swing speed will affect the welding and welding quality, because the speed
of the swinging and welding specification, welding speed (the speed of the
welding carriage), both sides pause time is together. In principle, is a welding
molten pool transition time is given priority to, the speed of the swinging, and
pause time on both sides) can guarantee on both sides of weld pool before and
after each covers more than half a molten pool advisable, form zigzag welding
speed is too slow. Too fast speed will cause the weld bead on both sides of the
weld bead fuse is not good, this kind of situation in the filling layer welding is
easy to produce slag inclusion.
4) The left and right pause time for swing shall be subject to the fusion of the weld
pool and the edge of the weld pass during the welding process. Meanwhile, the
front and back weld passes shall be superposition within one swing cycle.
Generally, the left and right pause time shall not exceed 100 [i.e., 1 second].

AMP-N150
12
For welding pass with wrong side, the pause time should be increased
appropriately on the wrong side to ensure the weld line fusion forming well.
5) The swing mode of digital control is adopted, and the adjustable speed has a
wide range in the welding process.
3. Welding specifications
1) The dry elongation length of the welding wire (the length of the welding wire
extending from the conducting nozzle) should be 10mm to 15mm. Too long is likely
to cause instability of the welding and poor gas protection;Too short molten pool is
not easy to observe, easy to plug welding nozzle, burn conductive nozzle.
2) It is advisable for the gas flow rate to be about 25L/min according to the scale of the
equipped flowmeter. Too large or too small will cause poor gas protection.
3) The welding current, voltage, the current, voltage, welding current is 180 a 28 v),
welding voltage, welding in the process of actual welding current, voltage
parameters matching situation depending on experience judgement, based on
current, welding voltage, welding arc length increases, then cause soft, drift,
welding arc is not stable, may even burn out conductive mouth;Welding voltage
decreases, welding arc length decreases, welding spatter increases, arc runout,
welding wire butt pool phenomenon, welding bead appearance formed welding,
resulting in red wire, non-combustion, welding wire burst. Take voltage as reference,
contrary to the above situation.The normal arc length is about 2mm.
4. Setting of welding machine
1) USES the overseas advanced welding power source, just press the button ignition
can realize automatic welding, arc extinguishing set to ensure the welding quality
of welded joint, the end of the especially in the big specification, when welding
with arc function, can guarantee the welding arc in forming, crater arc current,
voltage must adjust in advance and adjustment methods with reference to
electric welding specifications;
2) Select solid core or flux-cored wire switch by using the wire;
