N-7016-1

Specification

AWS Specification: AWS A5.1 E7016-1
JIS Specification: D4316
Other Specification: N/A

Description

N-7016-1 is a low hydrogen type electrode that features titanium and boron in its weld metal deposit
Exhibits high toughness at -60 degrees C and excellent crack tip opening displacement (CTOD) value

Application

Welding of aluminum-killed steels for low temperature service (N-TUF 33) for tructures to be used in frigid area, offshore structures, and cryogenic storage tanks

Remarks

Electrodes should be re-dried at 350 - 400 degrees C for 60 minutes

Optimum heat input in accordance with service conditions and plate thickness of structure should be applied in order to obtain desired toughness and CTOD value

Keep arc length as short as possible

Overlap method should be applied at the joining part of the bead
