Product Description

Product Description

SJ501
Product Description:
Aluminum-titanium sintered flux, basicity is 1.0, granularity is 10-40 mesh, bulk ratio: 1.2-1.5g /cm3. Ac or DC reverse connection is recommended. It is suitable for the occasions where the base material is not cleaned before welding, for the welding of low carbon steel, low alloy steel and heat-resistant steel, such as ships, boilers and pressure vessels, especially for the high-speed welding of thin plates, which has high requirements for the appearance of the weld.

Meet the standard:
AWS A5.17 F7A0-EL8
NB/T47018-2017

Scope of application:
With appropriate welding wire (such as H08A, H08MnA, H08MnMoA), it can weld low carbon steel and low alloy steel structures, such as ships, boilers, pressure vessels; Especially suitable for high-speed welding of thin plates.
Welding position:
Horizontal and horizontal welding

Note:
Prior to soldering, the flux must be baked at approximately 300-350 ° C (572-662 ° F) for 2 hours.
Before welding, it is necessary to remove rust, scale, primer and other impurities on the surface of the base metal to obtain excellent welding deposited metal.
In the case of multi-layer welding, the bottom welding of groove welding requires a small current and welding speed.
New flux is added regularly to prevent flux defects and poor bead surface forming caused by flux reuse.
