Stick Electrode

ArcSmart 816 AWS A5.5 E8016-G

Characteristics and Applications: ArcSmart 816 is a low hydrogen type electrode for all positioned welding of 550 N/mm2 grade high tensile steel. This electrode is reserved for the use of spherical storage tank. The welding can be done with excellent strength and good impact toughness after PWHT. It is suitable for A537 CLASS 1 and CLASS 2 plate.

Notes on usage: 1. Clean up the contamination on the base metal and welding seam so as not to derogate the weld metal quality from particles. 2. Dry the electrodes at 350-400 for 60 minutes before use. 3. Use back-step method to prevent arc starting from blowholes and hold for 3-5 seconds at every end-up. 4. Maintaining short arc length as possible is highly recommended. While welding with weave method, moving range should be controlled within 3 times of the wireâ&#x20AC;&#x2122;s dia. 5. When the heat input is excessive, the impact value tends to be reduced, therefore, proper heat input control is important to the impact value.

It has a wide application due to its low cost and excellent weldability. It is suitable for repairing cracks or breaks in cast iron.

Notes on usage: 1. Clean up the contaminations on the base metal and welding seam so as not to derogate the weld metal quality from crack and porosity. 2. Heat the welding portion to fully evaporate oil, liquor or solvent on it, normally the temperature is at around 400~500 . 3. Maintaining short arc length as possible is highly recommended. While welding with weave method, moving range should be controlled within 3 times of the wire’s dia. 4. Use intermittent weld and keep arc length short (not longer than 3”) or the prolonged heating might cause crack on joint edge. Symmetrical intermittent weld should be applied to multi-layer welding so as to balance the heat stress. 5. Pre-heating and slow cool-down is sometimes required, according to the metal’s type, shape and size. 6.To alleviate shrinking stress, proceed peening on and off at the temperature above 540 after welding to prevent crack or distortion.
