A bracket used for flux for submerged arc welding with small-diameter pillar on sphere tank. It includes a funnel

a thin arc plate

a dam-board

a rubber gasket

a junction plate and a bearing. The technique is this: first

put some flux on a thin arc plate

then put the bracket below the weld joint of the pillar and make the flux and the outside girth welds fit tightly

and solve the problem that it can’t employ automatic submerged arc welding to make inside girth welds of the pillar on sphere tank.
