Equivalent to Lincoln 760 welding flux
1.Description:
LH-SJ501 is a bonded type acid flux composed mainly of aluminium and oxides with ball form granule about 10-60 mesh in size.Its basicty is 0.5-0.8.It can be used on AC or DC power source.It provides good welding usability,easy slag removal,excellent anti-porosity property and beautiful bead appearance.
2.Applications:
In combination with H08A or H08MnA wire,this flux is suitable for welding of gascylinders,membrane water-cooled wall of boilers,ect.
3.CHARACTERISTICS:
1.LH-SJ501 is an agglomerated aluminate- rutile type flux.
2. metallurgical behavior: High silicon and manganese pick- up is obtained.
3.Grain size: 10 to 60 mesh.Basicity: 0.7( BIIW).
4. The welding performance is excellent.
Slag detachability is very good, especially at high speed.
Welding porosity scarcely occur.
5. Its welding speed can travel up to 120 cm/ min. It is particularly useful for welding tube- web- tube joints of finned tubes.
6.LH-SJ501 is useful for welding thin plate in single pass and limited pass.
7.The flux has low moisture pick-up and granular stability . As the bulk density is low so is the consumption rate.
4.Caution:
1.Damp flux should be re-dried at 300-350 Centigrade for 2 hours.
2.Rust, grease and moisture on the weldment should be removed before welding.

7.Our Factory 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 of GB/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.
