AWS A5.5 / ASME SFA5.5 E7016-G H4R
JIS Z3211 E4916-N1 AP L
EN ISO 2560-A - E46 6 1Ni B 1 2 H5
Notes on Usage
Welding Positions:
① Dry the electrodes at 300~350 ℃(572~662℉) for 60 minutes before use.
② Adopt back step method or strike the arc on a small steel plate prepared for this particular
purpose to prevent blow hole at the arc starting.
③ Pay attention not to exceed proper heat-input because excessive heat-input causes
deterioration of impact values of all-weld metal.
Applications
AWS A5.5 / ASME SFA5.5 E7016-G H4R can be used for welding of high tensile steel for low temperature. Such as off-shore structures, LPG storage tanks, etc.
Welding Position
Characteristics on Usage
AWS A5.5 / ASME SFA5.5 E7016-G H4R is an extra low hydrogen type electrode for all position welding of aluminum-killed steel and TMCP steel used at low temperature.
All-weld metal is 0.9%Ni type and better notch toughness and CTOD properties at -10 ℃
temperature. X-ray performance and usability are good.
