Many applications of ultrasonic-assisted methods were used during metal solidification,but they could not be introduced into weld pool. In this paper,a way of u
A new type of non-preheated hardfacing electrode was developed using H08A as the core and the coat contents including ferrotitanium, ferrovanadium, graphite, ru
The characteristics of temperatures, stresses and strains fields have been studied numerically for a titanium alloy sheet welded with an improved gas tungsten a
Impact pressuring diffusion bonding tests were carried out to produce joint between TA17 titanium alloy and 0Cr18Ni9Ti stainless steel. The reaction products an
In order to restore the degraded ultrasonic C-scan image for testing surfacing interface, a method based on support vector regression (SVR) network is proposed.
In this paper, the X-ray nondestructive test method of small defects in precision weldments with complex structure was presented. To resolve the difficulty of d
This investigation was performed to study acoustic field signal in order to improve RSW quality. Researchers firstly built an acoustic array sensor system,which
A digital control of pulsed gas metal arc welding inverter was proposed.A control system consisting of analogue parts was replaced with a new digital control im
It has been widely studied about the final residual stress and deformation in multipass welding of thick weldments. But there is a lack of a clear understanding
Nonlinear methods are used to analyze current signal of spot welding and the minimum embedding dimension,correlation dimension,the optimal time delay and the la
