4J36 gwiritsani ntchito kuwotcherera kwa oxyacetylene, kuwotcherera arc yamagetsi, kuwotcherera ndi njira zina zowotcherera. Popeza coefficient wa kukula ndi zikuchokera mankhwala a aloyi zikugwirizana ayenera kupewa chifukwa kuwotcherera kumayambitsa kusintha zikuchokera aloyi, ndi bwino kugwiritsa ntchito Argon Arc kuwotcherera zitsulo filler makamaka lili 0,5% kuti 1.5% titaniyamu, kuti kuchepetsa weld porosity ndi crack.

Njira yochizira kutentha
Annealing kuti muchepetse nkhawa	Kutenthetsa mpaka 530 ~ 550ºC ndikugwira 1 ~ 2 h. Kuzizira pansi
kuchepetsa	Pofuna kuthetsa kuumitsa, zomwe zibweretsedwe mozizira, zozizira zojambula. Annealing imafuna kutentha mpaka 830 ~ 880ºC mu vacuum, gwirani 30 min.
Njira yokhazikika	Muzoteteza media ndi kutentha kwa 830 ºC, gwirani 20min. ~ 1h, kuzimitsa Chifukwa cha kupsinjika komwe kumapangidwa ndi kuzimitsa, kutentha mpaka 315ºC, gwirani 1 ~ 4h.
Kusamalitsa	Sangakhoze kuumitsa ndi kutentha mankhwala Kuchiza pamwamba kungakhale sandblasting, kupukuta kapena pickling. Aloyi angagwiritsidwe ntchito 25% hydrochloric asidi pickling njira pa 70 ºC kuchotsa oxidized pamwamba.
