Kusvikira pakupera kwezana ramakore rechi19, nzira chete yekusimbisa yaive yekusimbisa simbi, iyo mhizha dzaive dzashandisa kwezviuru zvemakore kuti dzibatanidze simbi nesimbi nekupisa uye nekurova. Arc welding uye oxy-fuel welding yaive pakati pekutanga maitiro akavandudzwa mukupera kwezana ramakore, uye magetsi emagetsi emagetsi akatevera nguva pfupi yapfuura. Welding tekinoroji yakafambira mberi nekukurumidza mukati mekutanga kwezana ramakore rechi20 sezvo hondo dzenyika dzakatungamira kudiwa kwenzira dzakavimbika uye dzakachipa dzekubatanidza. Kutevera hondo dzehondo, matekinoroji mazhinji emazuva ano ekuwelding akagadzirwa, kusanganisira nzira dzemaoko senge yakadzivirirwa simbi arc welding, ikozvino imwe yenzira dzakakurumbira dzekusimbisa, pamwe ne semi-otomatiki uye otomatiki maitiro akadai segasi simbi arc welding, yakanyudzwa arc welding, yakasanganiswa arc welding uye electroslag.
