EXPERIMETAL INVESTIGATION OF TEMPEARTURE DISTIRBUTION IN ARC FUSION WELDING

Abstract

Experimental study of Heat transfer phenomena in welding process has been carriedout in the present work. The experimental study was carried out on six groups (eachconsists of two plates) of low carbon steel material. Each plate is rectangular in shapewith dimensions of (150mm x 200mm) with different thickness, (11mm) 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 edgedesign of joint welding for each group. Data Acquisition System (DAS) wasmanufactured and used in order to measure the transient temperature distribution ofthe models at the selected positions (channel (1) to channel (10)). The experimentalmeasurements showed that the maximum temperature occurs close to the fusionregion and starting to decrease a way from fusion region which is called unaffectedbase metal passing through the region of heat affected zone. The agreement of theresults are good a comparison with present experimental work. Confirm results thatwere carried out experimentally. The agreement of the results is good capability andreliability the experimental steps of calculating heat transfer in Manual Metal Arcwelding (MMAW).
