Abstract
We are presenting a study on zero-gap CO2 laser lap welding of multi-coated steel using alloying additives. Steel coated with multiple elements like zinc, nickel, aluminum, epoxy resin etc., being considered for use in fuel tanks for newer alternative fuels, was experimented and the effects of welding parameters on properties like porosity, hardness, bead quality etc. was investigated. An L-9 Taguchi experiment design was used to incorporate multiple multi-level processing factors. The results indicated optimal operating window for the material, which can be further optimized for real-time production.We are presenting a study on zero-gap CO2 laser lap welding of multi-coated steel using alloying additives.
