Abstract
PURPOSE: To enable the good penetration free from defects such as lack of fusion to be obtained by specifying the groove shapes, such as root hegith, root gap, the curvature of groove bottom and groove width, as well as the conditions, such as welding current, arc voltage and welding speed.
CONSTITUTION: In the narrow gap penetration welding of plates to be performed by using refractory backing strips, the groove root height H of the groove shape 4 of plates 3 is set at 4W6mm, the groove root gap G at 0W1.5mm, the curvature R of the groove bottom at 5W7mm and the groove width B at 9W14mm and a refractory backing strip 5 is placed on the back side. The welding conditions are set at welding current 290W350A, arc voltage 28W37V and welding speed 20W35 cm/min. Such specifying of the groove shapes and welding conditions makes arc stable, and enables the welding free from defects such as lack of fusion and the formation of good penetration.
