Analysis for Cooling Process of Arc Welding with Weaving Bead

Application of the Extreme Learning Machine for Modeling the Bead Geometry in Gas Metal Arc Welding Process

Rapid prototyping (RP) methods are used for production easily and quickly of a scale model of a physical part or assembly. Gas metal arc welding (GMAW) is a widespread process used for rapid prototyping of metallic parts. In this process, in order to obtain a desired welding geometry, it is very important to predict the weld bead geometry based on the input process parameters, which are voltage...

Visual Sensing Systems for Arc Welding Process

Visual sensing technology is widely used in welding practices because visual devices are decreasing in price, increasing in reliability and improving in image processing hardware and software. As the most studied welding sensor, CCD(Charge Coupled Device) is more suitable for quality control of welding process than other means of sensing devices because it can obtain both two dimensional and th...

Sensitivity Analysis for Prediction of Bead Geometry using Plasma Arc Welding in Bellows Segment

The automated welding systems, have received much attention in recent years, because they are highly suitable not only to increase the quality and productivity, but also to decrease manufacturing time and cost for a given product. To get the desired quality welds in automated welding system is challenging, an algorithm is needed that has complete control over the relevant process parameters in ...

Thermaltransport Phenomenon of Submerged Arc Welding Process

Original scientific paper In present work, thermal transport considering heat radiation by oval heat source shape and heat transfer of molten moving electrode was presented. In present paper, an analytical solution was presented by aggregating temperature increments caused by applying liquid metal and heat radiation of moving electrode. The assumptions for the study were heat source of temperat...
