AAC welding machine
AAC spot welding applied to reinforced mesh assembly process of
aerated concrete panel. Spot welding
machine produce the high-temperature electric arc to solder the
melting welding and welding materials when the positive and
negative poles in the momentary shorting. So that achieve the
purpose of they can combine together. Welding current,electrode
pressure, power time and electrode working surface size of the
welding parameters have a significant impact on the welding
Cycle spot welding and welding from four basic stages (spot welding
(1) the pre-pressure phase - the electrode is dropped to the
current which is connected phase, and the electrode is pressed for
the workpiece, so that the workpiece is appropriately pressed.
(2) welding time - the welding current passing through the
workpiece and producing heat to form the molten core.
(3) the maintenance time - cutting off the welding current, the
electrode pressure continues to be maintained until the melted core
is solidified to enough strength.
(4) the rest of the time - the electrode is beginning to lift the
electrode again and begins to fall again, starting the next welding
