An experimental and numerical study of laser impact spot welding
Materials & Design, 2015Abstract A novel solid state spot welding technique is developed, which utilizes laser induced shock waves to accelerate the flyer plate towards the base plate to obtain spot joining of similar or dissimilar metal plates. As a kind of no-contact, cold, and low energy input process, laser impact spot welding of Al/Al and Cu/Al with different weld spot

Impact of solubility on laser tissue-welding with albumin solid solders
Lasers in Surgery and Medicine, 2000The correlation between the solubility of solid albumin solders and their laser weld strength was investigated.Sections of dog intestine were laser welded with soluble or insoluble solid strips of solder. Two different treatments were followed for tissue soldering: "wet weld" and "dry weld." These treatments were chosen to assess the impact of ...
