Re: [MW:34149] Re: Advise for Weld defects during SAW Welding

Dear experts thank you for your valuable advises. 

The used consumables are

Wire : Cordiff 357 SA (Cr, Ni, Mo alloyed Tubular wire) Make - Diffusion

Flux: Supershield SS Flux ( Basic Flux, Neutral behaviour in terms of C, Cr, Ni & Mo pick-up or burn out)  Make: Super Alloys & Metals

because of very  high traveling speed and long weld bead.

Hi

First, you should give us sufficient information such as the AWS Classification, the wire and flux name, and the ASTM name of the material.

second, seemingly your welding speed has been high, I can see the long beads in the welding direction.

third, sticking the slag usually happens when the A is too high and the cause of porosity usually is moisture in the flux, have you baked the flux before use?

Dear Experts, 

There are few issues found during SAW weld  cladding at site and are highlighted in the report. Please find attached report.

I have a few questions

1. Reason for such issue to occur. 

2. Is the issue of Flux (neutral basic flux) or Flux cored wire used in the process.

3. Please advise how can this be sorted out.

Thank you,

George
