چکیده
|
Porosity is one of the main problems in welding of a516gr70 through flux core arc welding (fcaw); therefore, this paper is sought to investigate the effect of shielding gas composition on the rate of porosity and four modes of gas composition are considered for this investigation which include: in order to prove the validity of experiment, three samples are considered for each one of compositions that are totally 12 (4*3) and metal a516 gr 70 with a thickness of 10 mm was also selected for samples.

Abstract
|
Porosity is one of the main problems in welding of A516Gr70 through flux core arc welding (FCAW); therefore, this paper is sought to investigate the effect of shielding gas composition on the rate of porosity and four modes of gas composition are considered for this investigation which include: In order to prove the validity of experiment, three samples are considered for each one of compositions that are totally 12 (4*3) and metal A516 Gr 70 with a thickness of 10 mm was also selected for samples.
