Laser beam welding has wide acceptability due to least welding distortion, low labour costs and convenient operation. However, laser welding for dissimilar titanium and aluminium alloys is a new area which is having wider applications in aerospace, aircraft, automotive, electronics and other industries. The present study is concerned with welding parameters namely laser power, welding speed, fo...

copper–silver bimetallic strips were produced by cold roll welding process and were treated by diffusion annealing in the temperature range 250–800 ?c. the interface bonding strength was determined by bending and peeling tests, resistance, conductivity and micro hardness profiles were determined and microstructure in the interface region was observed by optical microscope. electrical resistance...

The most effective method to reduce CO2 gas emission from the steam power plant is to improve its performance by elevating the steam temperature to more than 700 ◦C. For this, it is necessary to develop applicable materials at high temperatures. Ni-based Alloy 617 and 12Cr steel are used in steam power plants, due to their remarkable mechanical properties, high corrosion resistance, and creep s...

Tungsten Inert Gas welding (TIG) process is an important component in many industrial operations. The TIG welding parameters are the most important factors affecting the quality, productivity and cost of welding. This paper presents the influence of welding parameters like welding current, welding speed on strength of low carbon steel on AA1050 material during welding. A plan of experiments bas...

Resistance spot welding is a simple process with high speeds and one of the most economical productive processes. It applied in various industries such as automobile, aircraft, home appliance; thus, demand for monitoring quality increasing. Owing to nature resistance process, there are several factors that can be monitored, dynamic value, which determined using current voltage measurements, dis...

Application of thermoplastic materials has increased dramatically in recent decades due to its recyclability, low density, resistance to chemical changes. The friction stir welding process is one of the new methods of solid state welding, which has recently undergone a significant improvement. In this research, using a new tool Made of plain carbon steel st37 in friction stir welding and low co...
