RE: [MW:5516] Re: POAK MRKS ON SAW WELDING

Here is an extract from lincon catalogue, they recommend L50 wire to avoid this or change the flux to 860

865… is a general purpose flux designed to weld butt joints and flat and horizontal fillets. 865 produces 70,000 psi tensile strength as welded or after short or long term stress relief. 865 flux should be used with L-50 electrode for optimum impact properties, resistance to rust porosity, and resistance to pock marking. L-61 may be used on steel free of scale and rust.

Dear Mr. Masthan,

Which company product you are using?We faced such kind of problem with ESAB filler and flux combination and eliminated the problem by introducing Lincoln products.The problem we faced only on surface profile of the weld bead(Radiography was OK).There was no metallurgical problem with ESAB products during SAW process.
