Abstract

The paper presents brief retrospective of progress and state-of-the-art of hybrid laser-plasma welding (HLPW). It is shown that the main objectives of HLPW include not only plasma-arc heating of item metal to increase its absorptivity, but also modification of welding thermal cycle to lower the rate of cooling after welding. This allows lowering the content of brittle structures prone to fracture in service. Moreover, presence of plasma-arc component of the process allows lowering the requirements to quality of fit-up of the butts to be welded, compared to laser welding. Prospects for introduction of HLPW into industry are related to its cost and technological advantages
