Wire and arc additive manufacturing (WAAM) has proven that it can produce medium to
large components because of its high-rate deposition and potentially unlimited build size …

Microperforated plate (MPP) absorbers are perforated plates with holes typically in the
submillimeter range and perforation ratios around 1%. The values are typical for …

Mechanisms for the formation of bead defects, such as humping, gouging, rippling, and
other unexpected surface patterns, encountered in welding or drilling are interpreted and …

Abstract A TIG–MAG hybrid arc welding process was proposed to achieve high speed
welding. The influences of hybrid arc welding parameters on welding speed and weld …

A self-designed external compound magnetic field assisted gas metal arc welding process
was developed to suppress the weld bead defects in high-speed welding. A comprehensive …

In order to understand the temperature fields, cooling rates and mixing in the weld pool, a
comprehensive, three-dimensional heat transfer and fluid flow model is developed and …

Three-dimensional numerical models are established to investigate the convection in
normal and high speed GMAW processes. A high speed photography system is used to …

Three-dimensional numerical simulations were conducted to study temperature distributions
and fluid flows during formation of humped beads in high speed gas metal arc welding …

The thermal condition and fluid flow in weld pool determine the formation of humping bead
in high speed gas metal arc welding. An external magnetic field is utilized to control the fluid …

The main aim of this work was to evaluate the influence and optimize the factors of the TIG-
MIG/MAG hybrid welding process on the geometry of the weld bead. An experimental design …
