Welding fume contains elements that, in their pure forms, can be hazardous to worker health if inhaled or ingested. Therefore, the chemical composition of welding fume must be examined when considering fume toxicity. Various chemical analysis techniques are presented and their applicability to airborne particles is described. Knowledge of particle size is important because a given characterizat...

We developed micropore membrane inlet mass spectrometer (MMIMS) probes to rapidly measure inert-gas partial pressures in small blood samples. The mass spectrometer output was linearly related to inert-gas partial pressure (r(2) of 0.996-1.000) and was nearly independent of large variations in inert-gas solubility in liquid samples. We infused six inert gases into five pentobarbital-anesthetized...

316L stainless steel joined to mild is widespread in several applications reach a requested good association of mechanical properties at lower cost. The activating tungsten inert gas (ATIG) weld was carried out using modified flux composed 76.63% SiO2 + 13.37% Cr2O3 10% NaF meet standard recommendations terms limiting the root penetration. Modified optimal gave depth penetration 1.84 times grea...

Sensing plays a key role in automating and controlling welding processes. Although arc light sensing has advantages over through-the-arc sensing for arc length control and seam tracking, the current technology relies on experimental data and lacks theoretical foundation. To improve measurement accuracy, this work addresses the theoretical foundation for arc light sensing. A theoretical model ha...

Mild steel has a wide range of uses such as in the construction field, automotive machinery industry, cookware, and pipeline. Metal Inert Gas (MIG) welding act an assembly method mild steel. Corrosion level is common problem that occurs MIG on In this study, suitable parameters voltage, number passes, were chosen experimental testing was planned by using Design Experiment (DoE) part Taguchi met...

This study contains experimental investigation and analysis of different joint design and parameters affecting welding distortion observed in gtaw process. Distortion is a major problem and it has different types. The extent of distortion depends on some important parameters related to welding. The important parameters chosen for given study are welding current, thickness, gas flow rate and joi...

The objective of this study is to predict the percentage dilution in AISI 1020 low carbon steel welds produced from tungsten inert gas welding using Artificial Neural Networking (ANN) approach. regression plot showed R = 0.9992 as progress training, 0.99865 validation and 0.85285 training test. This led overall correlation coefficient (R) 0.90007 which signified that ANN a robust tool for predi...
