MIG-MAG Kaynağında Duman Oluşumu

Öz

İmalat sektöründe geniş bir kullanım alanına sahip olan MIG-MAG kaynağı, bu prosesin doğası gereği, oldukça fazla miktarda zehirli ve sağlığa zararlı gaz-duman meydana getirmektedir. Dumanın kompozisyonu ve partiküllerin büyüklüğü kadar açığa çıkan dumanın miktarı da çalışan sağlığı açısından önem arz etmektedir. Duman miktarını belirlemek için özel olarak imal edilmiş duman kabini düzeneğinde deneyler gerçekleştirilmektedir. MIG-MAG kaynağında duman oluşum hızı (miktarı) üzerine çalışmalar yapan araştırmacılar, farklı koruyucu gaz kompozisyonlarının ve debilerinin, akım şiddetlerinin, ark gerilimlerinin, kaynak hızlarının ve serbest tel boylarının duman oluşum hızına olan etkilerini incelemişlerdir

Fume Formation In Gas Metal Arc Welding

Öz

Gas metal arc welding, which is widely utilized in manufacturing industry, generates significant amount of toxic and unhealthy gas-fume as a nature of this process. Besides fume composition and particle size, fume amount generated also is of importance in terms of worker’s health. In order to determine fume amount, experiments are realized in custom built fume chamber. Researchers, who studied fume formation rate in GMAW, have investigated the effects of different shielding gas compositions and flow rates, current intensities, arc voltages, welding speeds and wire electrode stick-out length on fume formation rate

Anahtar Kelimeler

• GMAW, emission, fume chamber, fume formation rate
