Description

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

 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.

 One-side welding defects such as hot cracking may occur with wrong welding parameter such

as high welding speed.

 Use Ar+20~25% COgas for welding.

THE   LATEST   NEWS

Is specialized (focus) on Manufacturing & Developing the Technology of Welding & Cutting industrials.

Along with the China/ Asia shipbuilding industrial developing, Wood Well Limited start to touch the shipbuilding associated biz and products, looks like: BWMS, Cutting Tools, Welding Machine, Pipe, Power Cable,CBM…..

And the industrial field enlarge to: Mold Maker, automotive, Pressure Vessel, Chemical Energy….

In order to strength our ability, we invest and cooperate with some good potential China manufactory on “welding & cutting” from 2007 Year.

 

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.

<!--[if !vml]--><!--[endif]-->

 

And we set the Japan Representative Office in Tokyo on 2014 Year.

It is help us upgrade our quality and service standard, and have the chance to cooperate with Japan famous company: Kyocera, Toshiba, Asahi….

 

On 2015 Year, we set the Brazil Representative Office in San Paulo.

The 2016 Rio de Janeiro Olympic Games will be hold son, we hope our products and service could win this market.

 

During the last 14 years developing, and all the Wood Well Staff hard working, now we have the 3 main division with 7 Section.
