A convex back side of weld

Postby Tungsteniac » Sat Jan 21, 2017 8:09 am

Sorry for my english. How to weld stainless steel pipe if need back side of seam had convex from 0.5 to 1.5 millimeters?
Seam showed under looks is not bad, but his back side is flat. Engineer-welder said me what by world standards back side of weld must be convex a few (from 0.5 to 1.5 mm).

Welders, when we welding a pipe then your back side of weld is convex or not (flat, a slightly concave)?
