Shielding gases are of considerable significance in the protection of molten metal from
atmospheric contamination during welding processes. These gases play an important role in …

Oxides in steel weld metals can initiate fracture or can improve toughness by influencing the
development of beneficial microstructures. In this work, the authors conducted experiments …

In order to adapt to the high temperature and heavy load process environment of large
forgings, a novel die with “fist-like” structure was designed. The iron-based welding material …

Hyperbaric arc welding is a special application of joining the pipeline steels under seawater.
In order to analyze the behavior of the arc under ambient pressure, a model is required to …

摘要研究了不同保护气(Ar+ 5% CO2, Ar+ 10% CO2, Ar+ 20% CO2 和Ar+ 30% CO2) 对1000
MPa 级高强熔敷金属组织及强韧性的影响. 结果表明, 当CO2 含量为20% 时 …

Effects of welding parameters such as welding current, voltage and travel speed on the
tensile strength of weld metal in flux cored arc welding were studied. The results were …

El objetivo del trabajo fue, en esta primera etapa, comparar las propiedades mecánicas y la
microestructura del acero HIC, aleado al Nb-Ti-Cu-Ni, resistente a la corrosión, con las del …

A soldagem pelo processo de eletrodo revestido é uma das mais utilizadas na indústria
metal mecânica. O conhecimento das propriedades mecânicas e microestruturais de uma …

The objective of this work was to study the effect that the utilization of different shielding
gases (CO2 and a mixture 80% Ar/20% CO2), welding position (flat and vertical up), arc …

The objective of this work was, in the first step, to compare the mechanical properties and
microstructure of the corrosion-resistant steel hydrogen-induced cracking, alloyed with Nb …
