Liropo tsa ho Welding AWS E7018 ke electrode ea tšepe ea carbon e koahetsoeng ka phofo ea hydrogen potassium e nang le hydrogen e tlase. Lerōle la tšepe le koahetsoeng le eketsa sekhahla sa depositi. E na le ts'ebeliso e ntle haholo e e lumellang ho ba le arc e tsitsitseng, ho fafatsa hanyane, ho tlosa slag ho bonolo ebile ho tjheseletsa maemong 'ohle. Tšepe e kentsoeng e na le thepa e ntle ea mechini e fanang ka ho tiea ho hotle haholo mochesong o tlase.
Molamu oa ho tjheseletsa oa AWS E7018 (electrode ea mofuta oa phofo ea tšepe ea motheo) o loketse ho tjheseletsa tšepe ea carbon le sebopeho sa tšepe e nang le motsoako o tlase, joalo ka Gr.50, jj.
