SPIE Proceedings, 1986
In this study, we have developed a concept of wound closure by laser welding and studied the wound healing process. In the first set of experiments, six-millimeter long, full-thickness incisions were made in the skin on the back of hairless mice. Control wounds were closed with interrupted 5-0 prolene suture.

Abstract Repair and maintenance of parts and components is carried out as a logical procedure that ensures the production of a usable and safe component or it can be approached haphazardly. This article describes the requirements and repair techniques of arc and oxyfuel welding processes to repair weld defects and structural failures. It

Welding in the World, 2010
A lot of trial and error is involved when it comes to repair welding of service exposed cast material like HP40-Nb used in the radiant section of steam cracking furnaces and many, different weld repair strategies are proposed in literature and applied by plant operators and weld fabricators.

Failures of Welding Repaired Pipeline
2008 7th International Pipeline Conference, Volume 2, 2008Enormous attention has been attracted to the safety issues regarding numerous pipelines that have had to be repaired by welding. The present paper describes experimental and numerical research conducted to assess the structural condition of welding-repaired pipeline, subjected to internal pressure including cyclic load.

Weld Repair of Irradiated Materials
Materials Characterization, 1999Maintenance of an accelerator for production of tritium will require replacement or modification of components that have been exposed to neutron irradiation. A primary repair option is welding, but conventional repair welding processes produced severe cracking in irradiated stainless steel.

RESISTANCE SPOT REPAIR WELDING OF SPOT WELDED STEEL SHEET
Materials and Manufacturing Processes, 2005ABSTRACT Repeated resistance spot repair welding over the poor spot weld and interface fractured spot weld of low carbon steel sheet has been studied. The repair welding has been carried out at different parameters to optimize the welding current, weld time, and electrode force as the primary welding parameters for maximum joint strength.
