JQ.SJ105


Introduction: JQ.SJ105 is a kind of ffluoride-basic type sintered flux for surfacing welding. The alkalinity is approximately 2.2. Round grains. The granularity is 2.0~0.28mm (10~60 meshes/inch). It has excellent welding performance, stable arc, good slag detachability and beautiful appearance of surfacing layer. The surfacing metal has excellent crack-resistance. If used together with appropriate wear-resistant submerged-arc welding wires, ideal surface hardness can be obtained. Direct current. The wire should be connected to the negative terminal.


Uses: If used together with appropriate wires (such as WM-210 wear-resistant alloy flux-cored welding wire), they can be used for surface overlaying on rollers.

Instructions:
1.The fluxes should be baked under 300~350℃ for 2 hours before using.
2.The stains on the weldments, such as rust, oil stains, moisture, etc., must be cleared away before welding.
