Elektrode Alxanka oo adag
Heerka: DIN 8555 (E6-UM-60)
Nooca Lambarka: TY-C DUR 600
Qeexitaanka & Codsiga:
· Elektroodh SMAW ah oo dahaar leh oo loogu talagalay dusha sare ee adag.
· Iska caabin aad u fiican oo ka dhan ah cadaadiska iyo saameynta cadaadiska.
· Guud ahaan waxaa lagu dabaqi karaa dahaarka qaybaha birta, birta la shubay iyo birta Mn-ka ee sare, oo isku mar la kulmi kara xoqid, saameyn iyo cadaadis. Meelaha caadiga ah ee loo adeegsado waa warshadaha dhaqidda dhulka iyo daaweynta dhagaxa, tusaale ahaan ilkaha qodayaasha, mindiyaha baaldiga, daanka burburinta iyo koonaha, dubbayaasha shiididda iwm.
