Fig. 4. Representative cross-sections of 6063-T6 aluminium alloy welds
with different edge distances – (a) more than 5mm (overlap joint
configuration); (b) within the range of 2-5mm; and, (c) less than 2 mm
(fillet lap joint configuration). Heat dissipation in each case is illustrated
by the arrow and the size of arrow represents the level of heat dissipation.
