Matching with corresponding welding wires of different grades,SJ103 can be used in these areas:

1  normal steel structures Q345 and Q395 , steels of boilers and pressure vessels,19Mng,16MR, and 15MnVR

2  Steels of bridges-building Q345q and Q370q

3  Pipeline steels  X65,X70 ,X80,X100 

4  Ship hulls steels A32,A40,D40,etc.


1. SJ103 is an agglomerated  fluoride-baisc  and low-hydrogen type flux 

2. Grain size: 10 to 40 mesh ,alkanity approximately 2.5

3. The ampere of SJ103's current carrying can reach to 1400A

4  It can be used for single-way or multi-way welding of  490MPA grade steel,the properties of deposited metal are of high  impact toughness and high crack reistance,

5  SJ103 can be used  for multi-way welding and narrow-gap welding of 590MPA grade steels

 Necessary process before welding:

1   Damp flux should be re-dried at 300-350 ºC for 2 hours.Rust,grease and moisture on the weldment should be removed before welding.

2   A sieve of 10-40 mesh is needed to screen out broken slags and dilicate power,when in recyle-use,to ensure the welding quality

 Factory Chief Introduction:

LAIWU HULING WELDING is one of leading biggest manufacturer of Submerged ARC welding flux in China. The annual capacity of production is growing and up to12000 metric tons of agglomerated flux and 5000 metric tons of fused flux. The factory has established the R&D laboratory with the advanced inspection equipments in field of welding materials. Our company is located at Laiwu City near by the Jinan International Airport, and also is near the TAISHAN Mount of Shandong Province, China.  
The Submerged-ARC welding flux has been approved and passed the inspection of quality with the province grade and the national grade in China. We strictly executed and produced the welding flux according to the industrial standards ofGB/T 5293-1999, GB/T 12740-2003, GB/T17854-1999 and the China Classification Society-1996 completely. Our quality management has passed IS09001-2008 Quality System Certification.
The welding flux has been widely used in the Chemical engineering equipment, Heavy machinery, Pressure vessel, Boiler, Gas cylinder body, Spiral welded steel pipe, Steel structure building H-beam steel etc. We have been exported the welding flux to India, Indonesia, Egypt, Japan, Philippine and Jordan. The foreign customer usually purchased and preferred to the high quality Agglomerated flux ( LH-SJ101;LH-SJ301;LH-SJ501;LH-HF101G ) and Manganese oxide fused flux.
