AWS A5.29 / ASME SFA5.29 E81T1-W2C
JIS Z3320 YFA-58W
Applications
GSF.81T1-W2C is designed for the welding of weather-proof steel for example corten A-242 or A-588.
Mainly used for flat and horizontal fillet welding on structural exposed steel usually found on buildings and bridges.
Characteristics on Usage
GSF.81T1-W2C is a titania type flux cored wire which can be used for all welding in conjunction with CO₂
shielding gas.
Notes on Usage
① Proper preheating(50~150°C)(122~302℉) and interpass temperature must be used in order to
release hydrogen which may cause cracking in weld metal when electrodes are used for
medium and heavy plates.
② One-side welding defects such as hot cracking may occur with wrong welding parameter such
as high welding speed.
③ Use 100% CO₂gas.

Is specialized (focus) on Manufacturing & Developing the Technology of Welding & Cutting industrials.
And the industrial field enlarge to: Mold Maker, automotive, Pressure Vessel, Chemical Energy….
From 2010 Year, we cooperate with LG, Samsung to agent and sales on China market.
The beginning products is from the Recycle Chemical Resin: HDPE, LDPE, and LLDPE.
Now we have developing the more cooperate field with LG, Taita , Samsung….
On 2013 Year, we open the China Independent Corporation in China Shanghai:
Shanghai D&Z International Trading Co., Ltd.
And have the China Representative Office at Dalian, Zhuhai,
And the same year we set the Indonesia Representative Office in Surabaya.
It is enlarge out biz scope from Asia to East-Asia.
On 2014 Year, we register the “GSC” Brand for production the welding & cutting materials.
It is widely apply on the industrial fields.
