Making medical stent in the way of laser spot welding of stainless steel wires L316

摘要

SEM scanning electron microscopy presented a relative uniform welding with no crack, time and laser beam energy must be set to achieve appropriate strength in such cases and finally obtain the best condition for receiving the best strength. Results of micro hardness testing on wires provided in dimensions of stent and wires which went away from the patient body showed that these wires are appropriate for making stent in this project.
