INFO.
•
In some cases, ripple patterns of the welded beads may not be precisely
visible depending on the type of material used, welding speed and the heat
input during welding. Especially, the patterns of welding materials such as
the SUS, a mild steel that takes time to harden, cannot be seen unlike the
welded beads of aluminum alloy welding.
•
There is a major relationship between the reduction of blowholes and the
measure of the melted metal’s vibration. The bigger the extent of the molten
pool, the bigger the vibrations as well; reducing more blowholes. On the
contrary, if the molten pool is small, then fewer blowholes will be eliminated.
If thicker beads are used for welding, the effects are bigger. However,
blowholes should not be taken away from all of the welding materials such
as extremely thick coated or oil-based steel products and cast materials.
•
If short-circuit occurs frequently while welding using soft aluminum, the
overview of the bead could appear black.
