Full penetration laser beam welding of thick duplex steel

Mar 31, 2016 · Full penetration high power bead on plate laser beam welding tests of up to 20 mm thick 2205 duplex steel plates were performed in PA position. A contactless inductive electromagnetic (EM) weld pool support system was used to prevent gravity drop out of the melt.

FULLY BUTT WELDED BEAMS Structural engineering

Mar 07, 2005 · Assuming the difference is small, you can use a full penetration weld, single bevel or "V", to splice the beams and provide continuity across the flanges. If the difference in size is substantial you won't be able to physically weld the flanges to provide continuity without some extra steel.

Joining I/H beams together WeldingWeb™ Welding

Welding shorter beams together was just tremendously appealing because it would mean not having to breach the outside wall of the house to position a long single piece beam. I'm confident in my abilities to perform the weld, but not producing a procedure welding isn't engineering.

Welding Wide Flange Splices Structural engineering

When you weld two wide flange together by cutting them square would it make sense to further strengthen the web by putting cover plates over the web? are not fillet welds on cover plate.. they are supposed to be full penetration weld on the main beam as shown. Are they not? But they look bad (or missed it) so I told the contractor to go
