[MW:14247] Re: Welding C45 (1045)

iHave used E 312-16 electrode form Hyundai very effectively for C45
to general steels welding with preheating as per thickness.
this electrode has a high resistance to cracking.
should you have the opportunity look into the use of the same and i
can guarantee satisfactory results.
