    Two Exceptional Performances by Wet Welding's Andersen Easywelds
     
    Case 1
    In 1987 Andersen Easywelds were used to do wet welding in +1000 fsw on a field job offshore Brazil. Since then Andersen Easywelds have done deeper and more substantial wet welding.
     
    Case 2
    A cast steel pipeline was girth wet welded in 32° water in 10 foot of depth on an emergency basis. There are many reports of petroleum pipeline repairs.
     
     
    The Wet Welding Andersen Easyweld's Testing
    Under US Navy Supervision there were Butt Welds done in the vertical and overhead positions in 21 fsw, 1.5 knot of current, 1 foot of visibility, 55°F sea water yielding a weld which had 2T bends and exceeded a US Navy Specification for surface welding
    Higher Strength steel (ABS Grade EH-32) was wet welded yielding a Vickers 10 hardness of 55 on the fusion line
    No micro cracks wet welding according to a micro
    Other Test Done and Ongoing
