2. Efecto del tiempo de superpulso de soldadura sobre la evolución microestructural de un acero de bajo carbono
ABSTRACT The Super Pulse arc type was developed to provide a solution to butt root pass beads in the semi-automatic welding process with gas protection (GMAW). Unlike standard pulse welding, the Super Pulse uses a sequence of different pulse waveforms to create a cord shape and appearance similar to the GTAW process. It uses higher amperage in the primary ph

3. Evaluation of the Effect of the Water in the Contact Tip on Arc Stability and Weld Bead Geometry in Underwater Wet FCAW
Abstract: Underwater wet flux cored arc welding – FCAW – is an important process employed to repair marine structures with the advantages of not handling the components off the water and offers higher productivity in comparison to other conventional welding process. Under the water, wet welding activities are performed with lower stability, due to the pr

4. A Study on Process Characteristics and Performance of Hot Wire Gas Tungsten Arc Welding Process for High Temperature Materials
Hot wire gas tungsten arc welding (HW-GTAW) process is the one where the filler wire is pre-heated close to its melting point before it is fed in to the arc. The effect of HW-GTAW parameters such as welding current, hot wire current and the wire feed rate during welding of super ASS 304H stainless steel tubes were evaluated in terms of heat input, voltage-cu

5. Weldability studies and parameter optimization of AISI 904L super austenitic stainless steel using friction welding
Welding input parameters play a very significant role in determining the quality of a weld joint. The quality of the joint can be defined in terms of mechanical properties, distortion and weld-bead geometry. Generally, all welding processes are employed with the aim of obtaining a welded joint with the desired characteristics. The purpose of this study is to

10. Caracterização de junta soldada por atrito linear com mistura (FSW) da liga Al-Mg-Si AA 6063. / Friction stir welded joint characterization of 6063 aluminum alloy.
Friction Stir Welding process arose from a desire to apply the principles and benefits of traditional solid state friction welding friction in non axi-symmetric geometries. Thus, it was added a traveling speed and a special rotating tool that allows welding aluminum alloys with bad weldability. The key factor to have a linear friction welding with sound bead
