ANALISA PERUBAHAN KUAT ARUS TERHADAP KEKUATAN IMPAK PADA PENGELASAN

Abstract

Welding is process of is tacking on two part of metal by melting both or second tip of part of metal to be jointed, and also with or filler metal withouh later then in made cool concurrently. extension of Las the including extension classification remain to, because this extension cannot be unloaded by tide without destroying material of extension and continued of material. Procedure in welding looked to be very easy, but in fact in it there are a lot of problem which must overcome by where sometimes result of welding disagree with delaying result of the welding and resolving of problems need kinds of - kinds of knowledge one of the him at this research. As for target of which wish to be reached by at this examination that is to know strong influence of current of welding to material strong. From result of welding of low carbon steel which given by strong variation of current, done by examination of impak to material. Result of this research can be concluded that strong influence of current influence delaying and is resilient the than welding of material become militant low carbon.
