Repair welding is not used enough in the industry 1 . One of the reasons for this lies in the insufficient and unrealiable knowledge in many segments of this area. A very important part is having appropriate knowledge of metallurgical processes in heating of the base material 2-4 . Unsuitable heating deteriorates the microstructure as it reduces toughness and fracture behaviour of the weld 5 . ...

Automating the welding process for the shipbuilding industry is very challenging and important, as this industry relies heavily on quality welds. Conventional robotic welding systems are seldom used because the welding tasks in shipyards are characterised by non-standardised workpieces which are large but small in batch sizes. Furthermore, geometries and locations of the workpieces are uncertai...

Metal arc welding ranges from primitive (manual) to increasingly complex automated welding processes. Welding occupies 1% of the labour force in some industrialised countries and increasing knowledge of health risks, necessitating improved assessment strategies and controls have been identified by the International Institute of Welding (IIW), ILO, WHO and other authoritative bodies. Challenges ...

Suture repair of a severed peripheral nerve is cumbersome, presents a focus for infection and neuroma formation, and does not always produce adequate stump alignment. An alternative form of repair is laser nerve welding, which is attractive because it does not introduce foreign material into the anastomotic site, it forms a circumferential seal, and it can be performed in difficult-to-reach are...

This report presents a method of arthroscopic repair of the peripheral triangular fibrocartilage complex tears that replaces traditional suture knots with ultrasonic welding of sutures. This will help eliminate potential causes of ulnar-sided wrist discomfort during the postoperative period.

Kunnayut Eiamsa-ard, Hari Janardanan Nair, Lan Ren, Jianzhong Ruan, Todd Sparks, and Frank W. Liou Department of Mechanical and Aerospace Engineering, Intelligent Systems Center, University of Missouri, Rolla, MO 65409 Reviewed, accepted August 3, 2005 ABSTRACT Nowadays, part repair technology is gaining more interest from military and industries due to the benefit of cost reducing as well as t...

In this paper, we developed the direct repair welding method without eliminating load when of great steel truss is going. According to information about process and data systematized, working for eliminate defect joint analyzing used FEM on stability result welding-repair were scientific more than last time at structure. When do did not from part so it’s necessity use any Jackie turning back. T...

Laser Aided Manufacturing Process (LAMP) can be applied to repair steel die/molds which are currently repaired using traditional welding process in industry. In order to fully understand the advantages of laser deposition repair process over traditional welded-repair process, the mechanical properties such as tensile strength and hardness of H13 tool steel samples produced by these two processe...

Repair welding (RW) with wire cladding is a common procedure to extend the in-service life of heavily loaded tool parts for die and mould industries 1-5 . The main advantages of repair welding are short downtime and cost efficiency compared to production of new tool part. Repair welding in general lowers the tool cost in the final part and enables higher added value to the die casting and injec...
