MEtallographic aspEcts of wEldings bEtwEEn orthodontic rings and ...

welding difficulties when the power degree was too
high, because the orthodontic ring effectively melted.
conclUsions
1. It is recommended to weld the orthodontic
rings using Wipla wire.
2. The tangential welding is much more
comfortable in comparison with the point-like one
and has better results.
