Xiang Welding Industrial Co Ltd
We are manufacture in Tianjin, China, We produce Sintered Flux, the standards are AWS F7A4-EH14,AWS F6A0-EM12,AWS F6A4-EM12,AWS F7A8-EH14,AWS F7A0-EM12,AWS F6A0-EL8,AWS F7AZ-EL8,AWS F6AZ-EL8


following features:
1, the high quality welded joint can be produced.
2, the arc is particularly suitable for the sheet welding because of it's stable burning and shallow melting depth.
3, the all-position welding as well as single-side welding and bi-side molding can be realized due to the easy operation.
4, the appearance of welded joint beautiful without spatter.



AWS F7A0-EM12
Sintered Flux
Sintered FluxAWS F7A0-EM12, is a kind of calcium-titanium sintered flux, with basicity of 1.0. The granular shape is round; size 2.0 ~ 0.28mm (10-60 mesh); color black. It has very good welding usability that enables it to have stable arc, the removal of slag is easy, and the bead appearance is nice. It is especially suitable for welding all kinds of round seam. The flux can be operated on DC/AC. The wires should be connected to the positive terminal when the welding machine is set to DC current.
AWS F7A0-EM12
Application
Sintered Flux, AWS F7A0-EM12  can be working with the right welding wires (H08A, H08MnA, and H08MnMoA) can weld ordinary structural steel and the steels that are used in boilers, pipelines.

Notes:
1. Flux must be baked at 300°C ~ 350°C for 2 hours
2. Impurities such as rust, oil stain and moist should be cleared before welding.
