Teknik pengelasan semakin banyak dipergunakan secara luas dalam proses penyambungan plat-plat besi, kontruksi bangunan dan konstruksi mesin. Salah satu metode yang sering dipakai, yaitu gas metal arc welding (GMAW). Tujuan penelitian ini adalah untuk mengetahui parameter terbaik pada Pengelasan GMAW terhadap struktur mikro, makro kekerasan Material ASTM A537 A653 DDS (galvanis). Metode digunaka...

In recent years, ultra-high-strength structural (UHSS) steel in quenched and tempered (Q+T) conditions, for example, S960QL has been found wider application areas such as structures, cranes, trucks due to its extraordinary material properties acceptable weldability. The motivation of the study is investigate unique capabilities electron beam welding (EBW) compared conventional gas metal arc (GM...

Salah satu jenis stainless steel yang cukup kuat, tahan terhadap korosi, mampu mencegah kontaminasi dan mudah dibersihkan adalah AISI 304 . Dalam aplikasinya di dunia industri penyambungan material ini sering menggunakan pengelasan, dengan parameter pengelasan berbeda-beda, sehingga akan berpengaruh sifat mekanis tersebut. Pada penelitian pengaruh dari arus mekanik pada gas metal arc welding (G...

The use of variants the gas metal arc welding (GMAW) process has become an affordable option in industry. Alternating current–gas (AC-GMAW) arises as one them, providing additional degrees freedom for controllability and versatility. This study focused on analysis a complex waveform AC-GMAW stainless steel, employed modern synergic programs, which not been widely disseminated technical literatu...

This paper describes a high-current Gas Metal Arc Welding (GMAW) process using constant voltage power source developed for high-efficiency welding of thick stainless steel plates. A short arc length as condition is preferable to concentrate the and obtain deep penetration plate welding. However, it easily found that an unstable derived from circuit happens irregularly by general purpose GMAW wi...
