Welding and flux must describe drying by using electrodes and flux after drying should be kept in an incubator 100-150 ℃, the welders welded steel silo insulation should be placed in the barrel, used with the check.

Learning the above welding, tacking, and then tell us about welding plate, arc board and led board settings.

Welded steel silo severely welding specifications set in accordance with national norms, steel plate welded joint library rules, the welding plate shall be affixed to the base material looks solid, groove gap should be appropriate to ensure that the weld penetration.

Know the needs of the welding groove, let's take a look at how the weldment is assembled step by step?

Butt agreed with the thickness of weldments counterparts dislocation, puzzle welds not more than 1mm, assembly welds not more than 2mm.

When the groove gap is too large, do not agree pad or steel reinforcement in the groove gap, when weldment assembly groove when the gap beyond 5mm, but the length ≤ 15% total length of the weld, promised for surfacing disposal, surfacing after the weld groove shall be grinding to the original requirements.

Here is a look at what tack welding?

Welding quality requirements and technical measures and formal tack welding seam, like tacking welding shall bear holding a certificate of competency by welders.

Positioning the weld strength must be welded should be, but the thickness is typically not to exceed half of the weld becomes usually 4-6mm, positioning the weld length is typically 30-60mm, not to exceed a distance of 400mm appropriate.
