Although additive manufacturing (AM), or three dimensional (3D) printing, provides
significant advantages over existing manufacturing techniques, metallic parts produced by …

The effects of many process variables and alloy properties on the structure and properties of
additively manufactured parts are examined using four dimensionless numbers. The …

Printing overhang structures by laser-powder bed fusion (L-PBF) additive manufacturing
remains challenging due to warping distortion. This paper studies the warping formation of …

This paper aims to present a comparison on the use of different heat treatment conditions in
association with welding of a HSLA-80 steel. This investigation was carried out by multipass …

The demand for lightweight structures in ship fabrication to improve performance and fuel
savings has led to increasing use of thin-section structures. However, welding such …

Residual stress measurements were performed on DMR-249A steel weld joints fabricated
by shielded metal arc welding (SMAW) and activated flux gas tungsten arc welding (A …

In this work, tandem metal inert gas (MIG) welding using double torches with each torch
contained a single wire feed was conducted to join AA5083 aluminium alloy plates. In order …

In wire arc additive manufacturing (AM), as in arc welding, arc heat thermally deforms
substrates and articles. For industrial applications, deformation characteristics of various …

A thermo-elastic-plastic numerical method based on the hybrid inversion combing
experiment results and numerical results was developed. The influence of various factors in …

Distortion induced by welding process is one of the major problems found in shipbuilding
industries. Significant loss in time and cost to correct and repair this welding defect occurs …
