Product Description

Product Description

Product Name:
HW751T welding flux for LPG Cylinder, pipemile,  pressure vessure
Specifications and Compliance:
GB/T5293-2018  S49A4AR-SU34
AWS A5.17M  F7A2-EL12 F7A4-EM12K F7A4-EH14
General Information:
Basicity Index:1.1
Grain Size:14-50 mesh
Density:1.3g/cm³
Polarity:DCEP/AC
Application:
HW751T welding flux is not sensitive to rust, scale, primer and dirt on the surface of the base metal. It is suitable for the situation when the base metal is not strictly cleaned before welding. It has excellent porosity resistance and good moisture resistance. The slag solidification is fast. There is no slag drip phenomenon during circumferential seam welding with small diameter. It is especially suitable for circumferential seam welding. It has good welding performance, soft arc, easy slag removal and good weld bead. The number of welding layers is limited and the maximum welding layer is three. It is used for welding regular pressure vessels, structural steels, pipeline steels and gas cylinders. It is especially suitable for the welding of pressure vessels such as LPG tanks and gas cylinders.

Notes:

1.Re-dry the flux at 300-350ºC for 60 minutes before welding.
2.Remove rust, water scale, primer and other contaminants on the base metal before welding to obtain excellent weld deposit.
3.Add new flux regularly before using the recycled flux to prevent defective weld bead.
