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 wire’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.

T-Cast Characteristics and Applications: T-Cast is a low hydrogen type electrode with mild steel core rod. It is designed for the welding of cast iron when machinability of deposited metal is less considered. The welding can be done with stable arc and less porosity. 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.

Characteristics and Applications: TL-78A1 is an iron powder low hydrogen type electrode for 490N/mm2 high tensile steel. It provides high welding efficiency due to the pick-up of iron powder. The weld metal contains 0.5% Mo , therefore it is suitable for chemical plants, petroleum refinery plants, 0.5%Mo heat-resistant steel and other casting steels.

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 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 wire’s dia. 5. Do not exceed the range of recommended current. Over heat input might decrease the impact value. 6. Pre-heat the workpiece at 100~200 and PWHT at 620~680 .

While welding with weave method, moving range should be controlled within 2.5 times of the wire’s dia. 3. Dry the electrodes at 250~300 for 60 minutes before use. Take out consumables for half day consumption and keep in the environment at 100~150 during welding process. 4. Use lower current to prevent from crack and minimize base metal dilution.
