Abstract
High Speed Resistance Welding (HSRW) is a high-volume manufacturing route
for the production of welded steel cans. Full optimisation of such a process
requires a scientific understanding of the relationships between process variables
and thermal effects occurring in the weld zone and heat affected zone. This paper
follows on from previous work undertaken as part of an ongoing project to
develop a predictive FE computer model of the HSRW process. Presently, the
model has been used to investigate the thermal effects of welding speed and A.C.
frequency on the macro scale evolution of the nuggets developed during
welding. The model formulation and results generated using the model are
described. The effects of varying strip speed and A.C. frequency on temperature
distributions, current density fields and predicted nugget lengths are highlighted.
Keywords: high speed resistance seam welding, weld nugget, thermal
behaviour, current density.
1 Introduction
Welded steel cans represent the most predominant form of metallic packaging
for human and pet food products, worldwide [1]. Although high-speed resistance
welding lines with linear speeds of over 1ms-1 have been developed, extra
demand is being imposed on process capability and product performance. To
utilise this process to its optimum capability and to increase the welding latitude
Keywords
high speed resistance seam welding, weld nugget, thermal
behaviour, current density.
