Experimetal investigation of tempearture distirbution in arc fusion welding

Abstract EN

Experimental study of Heat transfer phenomena in welding process has been carried out in the present work.

The experimental study was carried out on six groups (each consists of two plates) of low carbon steel material.

Each plate is rectangular in shape with dimensions of (150 mm x 200 mm) with different thickness, (11 mm) for groups (1) and (2) from A285 grade (B), ((16mm) for groups (3) and (4) from A 285 grade (C), and (19mm) for sets (5) and (6) from A285 grade (A) using single V-Butt edge design of joint welding for each group.

Data Acquisition System (DAS) was manufactured and used in order to measure the transient temperature distribution of the models at the selected positions (channel (1) to channel (10)).

The experimental measurements showed that the maximum temperature occurs close to the fusion region and starting to decrease a way from fusion region which is called unaffected base metal passing through the region of heat affected zone.

The agreement of the results are good a comparison with present experimental work.

Confirm results that were carried out experimentally.

The agreement of the results is good capability and reliability the experimental steps of calculating heat transfer in Manual Metal Arc welding (MMAW).
