8. Weld ƒe wɔwɔme madeamedzi .
Weld ƒe wɔwɔme madeamedziwo dometɔ aɖewoe nye: weld ripples manyomanyo, weld siwo mesɔ o, tɔtrɔ si mesɔ o le weld kple base gas dome, weld dahewo, kple weld siwo mesɔ o.
Nusitae nɔnɔme sia le:
Ne wotsɔ weld seam la blae la, ka si wotsɔ ƒoa ka la meli ke o, alo kekelia meyina edzi o.
Ŋuɖoɖo:
Trɔ asi le mɔ̃a ƒe liƒo ŋu.
9. Welding .
Weld Bead fia: Ne weld ƒe mɔzɔzɔa trɔ ŋutɔ la, weld bead alo uneven forming nye nusi dzena le dzogoea dzi bɔbɔe.

Weld le parameter nyuitɔwo te, trɔ asi le dzogoe si dzi nàkpɔe le ŋu be dzogoeawo nawɔ ɖeka.
10. Anyigba ƒe slag ƒe gomekpɔkpɔ le eme .
Surface slag inclusions ƒo nu tso: le welding ƒe ɖoɖoa me la, ŋutigbalẽ ƒe slag inclusions siwo woate ŋu akpɔ tso egodo la dzena le ƒuƒoƒoawo dome koŋ.
Susu me dzodzro le anyigbadzi slag inclusion ŋu:
A. Le multi-layer multi-pass welding me la, interlayer coating la mele dzadzɛ o; alo weld ƒe ƒuƒoƒo si nɔ anyi va yi la ƒe anyime mele gbadzaa o alo weldment la ƒe anyime meɖo nudidiawo gbɔ o.
B. Welding dɔwɔwɔ ƒe mɔnu siwo mesɔ o abe low welding input energy kple welding ƒe duƒuƒu kabakaba akpa.
Ŋuɖoɖo:
A. Tia welding current kple welding ƒe duƒuƒu si sɔ. Ele be woakɔ nusiwo wotsɔ blaa nuawo dome le multi-layer multi-pass welding me.
B. Grinding Be woaɖe weld seam kple slag inclusion le anyigba dzi, dzra welding ne ehiã.
