A weld in which the ends of the pieces are overlapped and then joined by welding.
Lap welding made by tilting the plates to be welded,So that the weld is flat.the electrode should point to the centre of the "V" at 45 degrees to the plate and 60 degrss to the line of weld.The correct correct penatration can be obtained can be obtained in the lower plate which has greater mas by causing the slight weave to hesitate slightly on this plate. Welds should be then made with the plates flat and metal controlled so as to get a bead of good section .A wedge inserted to the lower plate, which will enable the joint to be broken open for inspection.When a uniform regular bead can be obtained,specimens can be prepared, these welds are 30% stronger than the same length
of normal weldings.
