The oscillating phenomenon of the weld pool has a direct physical correspondence with its penetration state, which broad application prospects in monitoring states. This article studied characteristics short-circuiting gas metal arc welding (S-GMAW) different states based on high-speed photography system. results show that form liquid bridge electric explosion impact is “surface impact” S-GMAW....

The weld penetration under different plasma welding currents was compared in the plasma-gas metal arc (GMAW) hybrid of aluminum alloy. When current lower than 150 A, greater sum single and GMAW penetration. reached 130 with increase current, advantage gradually weakened, that welding. above change mechanism is revealed from heat source energy distribution molten pool stress. results show when 1...

Joints of complex phase 780 (CP-780) advanced high strength steel (AHSS) were carried out by using an ER-CuAl-A2 filler metal for the gas arc welding pulsed brazing (GMAW-P- brazing) process and ER-80S-D2 GMAW-P employing two levels heat input. The phases in weld bead HAZ analyzed, evaporation zinc means scanning electron microscopy (SEM) was also monitored. mechanical properties welded joints ...

Recently, deep learning has been applied to various welding techniques, such as laser welding, gas metal arc (GMAW), and resistance spot research on automation quality prediction is being conducted. Even for GMAW, many researchers have attempted predict through X-ray, current, voltage measurements. If judgment in real time not necessary, it most effective judge the of a welded part using an ext...

Proses dengan las 70o 110o serta menggunakan arus 95A, 125A, 155A 185A. Metode eksperimen. Pengambilan data observasi langsung ...

METAL transfer describes the process of the molten metal movement from the electrode tip to the workpiece in gas metal arc welding (GMAW). A better understanding of the metal transfer process is important for improvements in the quality and productivity of welding. While several distinct modes of the metal transfer have been classified,[1] the globular and spray transfer modes have received att...

In recent years Gas Metal Arc Welding (GMAW) technology has expanded its functionalities in various areas which have further motivated usage several emerging manufacturing industries. There are issues and challenges associated with this technology, especially dissimilar metal welding (DMW). One of the predominant is selecting appropriate parameters influence efficiency technology. To explore mo...
