Material Weldability Chart
The materials weld-ability chart below is a valuable reference tool when designing components and materials to be electron beam welded together. Some materials are easily electron beam welded while other are difficult but can be done and of course.....some just should not be tried. Please use this as a guide, it is not mean to be a bible - it is always prudent to contact EBTEC Corporation to speak with an electron beam welding expert, as well as submit weld-ability samples before finalization of design.
W
= Weldable
X = Not recommended (cracking or other problems)
D
= Difficult to weld or requires special techniques
M
= Difficult to weld - magnetic deflection problems
Blank
= Weldability unknown
Notes:
1) Free machining grade alloys, such as 416, 420F, 430F,
and 303 are not suitable for electron beam weldingNew Paragraph
