tariby welding flux-cored, 550Mpa alkaline vy ambany.
Ny endrika tsara tarehy, ny fanesorana slag tsara, ny setroka tsy dia misy, miaraka amin'ny teknolojia welding tena tsara, mety amin'ny fanodinana mitsangana midina.
Izy io dia manana hamafin'ny mari-pana ambany tsara, fanoherana ny crack ary ny fanoherana ny porosity.
