INITIAL ARC IGNITION CONTROL IN GAS-SHIELDED WELDING
The control method of the initial arc ignition in the gas-shielded welding is offered. It is based on the short-circuit current limitation after heating the wire stick-out with the metal passing current to the plastic state for the time of the wire ...

Systematic study of effect of cross-drafts and nozzle diameter on shield gas coverage [PDF]
A shield gas flow rate of 15–20 L min21 is typically specified in metal inert gas welding, but is often adjusted to as high as 36 L min21 by welders in practice. Not only is this overuse of shield gas wasteful, but uncontrolled high gas flows can lead to

An investigation of abrasive wear and corrosion behavior of surface repair of gray cast iron by SMAW
In this work, improving the abrasion–corrosion behavior of gray cast iron used in centrifugal pumps was studied. These pumps are usually made of gray cast iron (BS:1452Gr220) and are repaired by Shielded Metal Arc Welding (SMAW).

The Influence of Shield Gas Compositions on the Arc Temperature in Gas-Shielded Metal-Arc Welding
The influence of shield gas compositions in argon-nitrogen, argon-oxygen, argon-carbon dioxide and argon-hydrogen systems on the arc temperature was studied by means of the spectral line intensity method.The findings in this work are as follows:1) The arc temperature increases slightly with an increase of welding current.2) The arc temperature does not
