Studying heat-affected zone deformations of electric arc welding
, 2018 The paper studies the influence of the most common defects in permanent electric arc welds made during the welding butt joints in infield oil pipelines, onto the strength characteristics of the welded pipe material around the heat-affected zone.

Internal wire guide for GTAW welding [PDF]
, 1989 A welding torch for gas tungsten arc welding apparatus has a filler metal wire guide positioned within the torch, and within the shielding gas nozzle. The wire guide is adjacent to the tungsten electrode and has a ceramic liner through which the wire is ...

steel research international, EarlyView.This study analyzes the thermal and mechanical behavior of activated tungsten inert gas welding on 4 mm‐thick Grade 91 steel, widely used in high‐temperature applications. Using a combined heat source model, the research predicts weld distortion and residual stress, validated through experiments.

Use of audible sound for on-line monitoring of gas metal arc welding process [PDF]
Metalurgija, 2008 In this paper sound generated during the gas-metal arc welding process was studded. Experimental analyses of the acoustic signals have shown that there are two main noise-generating mechanisms, first having impulse form is arc extinction and arc ignition;

Metallurgical characteristics of armour steel welded joints used for combat vehicle construction
Defence Technology, 2018 Austenitic stainless steel (ASS) and High nickel steel (HNS) welding consumables are being used for welding Q&T steels, as they have higher solubility for hydrogen in austenitic phase, to avoid hydrogen induced cracking (HIC) but they are very expensive.

Influence of Higher Tramp Element Level on the Weldability of Automotive Steels
steel research international, EarlyView.The use of green recycled steels is constantly expanding in the automotive industry. The increase in tramp elements resulting from the recycling of steel is problematic. Tramp elements can lead to a negative influence on the weldability. To understand the influence, the welding properties of three green steels are characterized. The potential limits of

Method for defect free keyhole plasma arc welding [PDF]
, 1993 A plasma arc welding process for welding metal of increased thickness with one pass includes operating the plasma arc welding apparatus at a selected plasma gas flow rate, travel speed and arc current, to form a weld having a penetration ratio to weld ...
