Influence pulse shaping in laser welding of aluminium on the quality of welds

The difficulty in laser welding of aluminium is occurrence of various defects such as porosity, hot cracking, and underfill of weld. This paper describes the influence of pulse modulation and pulse shape on the quality of weld made on the aluminium alloy EN AW- 6082 (AlMgSi1).
