Today, the quality of welded seams is often examined off-line with either destructive or non-destructive testing. These test procedures are time-consuming and therefore costly. This especially true if welds not accurately due to process anomalies. In manual welding, experienced welders able detect anomalies by listening sound welding process. this paper, an approach transfer “hearing” welder in...

The aim of this study is to investigate the optimization process parameters for Metal inert gas welding (MIG). In the present work, bead-on -plate welds were carried out on MS 5986 Fe 410 carbon steel sheets using Gas Metal Arc Welding (GMAW) process. In this present investigation ER70S-6 solid wire having 1.2 mm diameter was used as an electrode with direct current electrode positive polarity....

Gas metal arc welding (GMAW) is a process in which an electric formed between wire electrode and workpiece alongside shielding gas to protect the from contaminants. There are several ways molten droplet can be transferred weld pool known as transfer modes. Identifying mode automatically essential monitor control process, especially automated processes employed modern Industry 4.0 manufacturing ...

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...

Baja ASTM A36 banyak digunakan di dunia industri pada bidang manufaktur seperti pengelasan GMAW. Penelitian ini dilakukan untuk melihat pengaruh variasi sudut saat proses GMAW terhadap nilai kekerasan dan struktur mikro hasil pengelasan. Spesimen yang yaitu tebal 10mm. Proses dengan las 70o 110o serta menggunakan arus 95A, 125A, 155A 185A. Metode eksperimen. Pengambilan data observasi langsung ...

A gap is generated in the weld joint due to dimensional error of welded parts and thermal deformation aluminum alloy’s gas metal arc welding (GMAW) process alloy. The optimum conditions corresponding different gaps are required field. In this study, were optimized using Taguchi’s design experiment method response gaps. Al5083-O with a thickness 4.0 mm was used as base material, GMAW performed o...
