Wonder if anyone has experienced problems with honeycomb type blow holes appearing in and adjacent to the weld pool area, when welding relatively thin aluminium castings? I get the feeling this might possibly be hydrogen inclusions of some sort, maybe caused by shielding gas issues?
Only seems to occur on castings which are thinnish and which may well be made out of low grade material (various motorcyle parts). Be very helpful if anyone has had the same sort of problems and found a way to overcome them..........
