Keyhole behaviour during laser welding of zinc-coated steel
The production of consistent, high-quality laser welds on zinc-coated steels for the automotive industry remains a challenge. A simple overlap joint geometry is desirable in these applications but has been shown to be extremely detrimental to laser welding because the zinc vapour formed at the interface between the two sheets expands into the keyhole and disrupts fluid flow in the melt pool, wh...
متن کاملOxidation resistance of plasma coated and laser treated mild steel
Stainless steel powder was coated on mild steel substrate using plasma coating. The porous coating thus obtained was modified using laser irradiation. The oxidation behaviour of the plasma coated as well as laser treated material was studied in air at 1073 K. There was considerable decrease in oxidation rate of mild steel after plasma coating as expected. In addition the oxidation resistance im...
متن کاملDissimilar resistance spot welding of AISI 1075 eutectoid steel to AISI 201 stainless steel
In this paper, dissimilar resistance spot welding of AISI 1075 eutectoid steel to AISI 201 stainless steel is investigated experimentally. For this purpose, the experiments are designed using response surface methodology and based on four-factor, five-level central composite design. The effects of process parameters such as welding current, welding time, cooling time and electrode force are inv...
متن کاملInvestigation of structural changes in resistance spot welding of advanced high strength steel DP590
The structural and hardness developed in advanced high-strength steel DP590 have been investigated with the help of optical microscopy and scanning electron microscopy on resistance spot welded specimens. The hardness diagram of the weld sections was prepared by microhardness test and the temperature peak and heat distribution were simulated by menas of the Abaqus software. The results show tha...
