Hygroscopicity of mild steel and 50-kgf class steel welding materials.

Blue-light hazard from CO2 arc welding of mild steel.

OBJECTIVES The objective was to quantify the blue-light hazard from CO(2) arc welding of mild steel. METHODS The spectral radiance of arcs in CO(2) arc welding of mild steel was measured for solid and flux-cored wires at welding currents of 120-480 A. Effective blue-light radiance and the maximum acceptable exposure duration were calculated from the spectral radiance using their definitions i...

Parametric Optimization of TIG Welding on Stainless Steel (202) & Mild Steel by using Taguchi Method

The main objective of industries reveal with manufacturing better quality product at low cost and increase productivity. TIG welding is most vital and common operation use for joining of two similar or dissimilar parts with heating the material or applying the pressure by using the filler material for increasing productivity with less time and cost constrain. The TIG welding parameters are the ...

A mortality study among mild steel and stainless steel welders.

A mortality study was carried out in conjunction with the European mortality study among welders coordinated by the International Agency for Research on Cancer (IARC). The study was aimed at assessing risks for lung cancer in relation to exposure to asbestos, welding fumes containing chromium and nickel, and tobacco smoke. The study included a cohort of 2721 welders and an internal comparison g...
