AWS A5.20 / ASME SFA5.20 E71T-12M-J
EN ISO 17632-A-T 46 4 P M 1 H5
Applications
Oil and gas construction, pipe, and off-shore structures.
Characteristics on Usage
GSF. 71T-12M-J is a titania type flux cored wire for all position welding. It provides excellent notch toughness at low temperature, not only as-welded but also stress relieved state.
All position welding can be achieved with excellent flat bead appearance, less spatter and easy slag removal and high welding current in vertical up position can be performed.
Notes on Usage
① Proper preheating (50~150°C)(122~302°F) and interpass temperature must be used in order
to release hydrogen which may cause crack in weld metal when electrodes are used for medium
and heavy thick plates.
② One-side welding defects such as hot cracking may occur with wrong welding parameter such
as high welding speed.
③ Use Ar+20~25% CO₂gas for welding.

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.
