Flux Cored Wires

1011

Characteristics and Applications: ArcStar 81N1M is a gas-shielded flux cored wire for all-position welding. It is designed for welding 590

N/mm2 high tensile steel for low temperatures. It provides good weldability with smooth bead appearance, less spatter and stable arc as well as good

impact properties down to -40�

. It is also suitable for welding on construction machinery, shipbuilding, offshore, structures, bridges,

storage tanks and piping.

Notes on Usage: 1. When the heat input is excessive, the impact value tends to be reduced. Therefore, perform welding with

selecting proper heat input depending on the required impact value. 2. Preheating at 50~150

� is required depending on steels, plate thickness and restraint.

3. Use DC(+) polarity.

4. Use 75~80%Ar+25~20%CO2 as shielding gas.

Characteristics and Applications: ArcStar-101K3 offers excellent arc stability and low spatter with CO2 shielding gas. It also has a fast freezing slag for all-position welding. These features, along with relatively low diffusible hydrogen levels, excellent slag removal, good impact values and high strength levels, make ArcStar-101K3 a superior choice for welding higher-strength steels.

Notes on usage: (1) Use (DC+) polarity. (2) Use 100%CO2, 20~25 l/min shielding gas. (3) Welding heat input must be controlled in order to get required impact value, since notch tough

ness tends to decrease due to excessive heat input. (4) Keep dry during handling and storage.

It is able to obtain the weld metal with good resistance to wear under wide range of welding parameter owing to its high hardness of weld metal and low penetration.

It is suitable for hardfacing of bulldozer blade, bucket lip, tipper teeth, the parts of impeller subjected to severe soil abrasion.

Notes on usage: 1.The pre-heat and inter-pass temperature should be kept over 300

� and should be slowly cooled to room

Characteristics and Applications: TWH-67-O is a self-shielded flux-cored wire developing a ledeburitic structure with a great amount of

embedded Chromium Carbides and super-hard Metalborides. The alloy is specifically designed for extreme abrasive wear at high temperatures. The deposits can’t be flame out, heat-treated, machined or forged except grinding.

It is used for blast furnace bell, sugar cane industry, bucket teeth and coke oven screen etc.

Notes on usage: 1. For hardfacing the high-carbon steel or the low-alloy steel, the welding consumables of the austenite

stainless steel could be welded as buffer layer. 2. Too many layers might cause crack. In need of welding many layers, the bead of rib or waffle pattern

should be applied.

Characteristics and Applications: TWS-420-S is a submerged arc flux-cored wire that matches with TF-81 neutral flux to produce the weld

metal of AISI 420 martensitic stainless steel. It offers excellent resistance to fire cracking, corrosion and unlimited deposition thickness. It is used for workpieces such as continuous casting rolls and steel mill rolls for high temperature service.

Notes on usage: 1. When the carbon content of the carbon steel workpiece is over 0.8 wt% or that of low alloy steel workpiece

is over 0.35wt%, a buffer layer using mild steel filler metal (root-pass welding by TWH-31-S or TWH-34-O with around 300~400

� pre-heat treatment) is helpful for further hardfacing.

2. The pre-heat and inter-pass temperatures between 200-420� should be kept for massive workpieces, heavy cylinders and highly stressed workpieces to prevent weld cracking.
