Subject: [MW:1150] SAW - For Single sided jointPREM S NAUTIYAL
Dear Friends
We are trying to establish SAW for single sided joint. The base metal is SA516Gr.70. The joint is 25mm thick. The joint is a single bevel groove but joint with included angle of 45degree ( one member is vertical and there is bevel on other member).The final NDT is UT.
Presently we are welding this joint with TIG+SMAW.The joint is circular hence ideal for SAW.
Now we want to try to weld this single sided joint completely with SAW. This is for productivity improvement.
Is it possible to weld this joint having no access from other side with SAW completely ?
Can we keep zero gap, zero rootface, and achieve full penetration joint with SAW??
If yes what should be the parameters, wire dia., etc.
We dont want to use any ceramic backing.
Can anyone suggest how to weld this joint completely with SAW.
This is a development activity. Please share your experience...
Regards
Prem Nautiyal

Why not GTAW+SAW? Full SAW may not give you full penetration + defect free in UT
