Iimpawu kunye nesicelo
I-AWS A5.1 E7018-1 H4 Iintambo zokuwelda, i-electrode yokuwelda yi-electrode ye-iron-powder low hydrogen yohlobo lwe-welding ye-all-position yentsimbi eqine kakhulu ye-490N/mm2 grade. Yenzelwe ukusetyenziswa kwe-single and multiple pass. Le mveliso inomtsalane omhle wokuwelda kwaye ivelisa i-arc ezinzileyo ene-spatitter generation ephantsi. Ivelisa iintsimbi zokuwelda ezineempawu ezintle zoomatshini kunye nokuqina kwempembelelo kubushushu obuphantsi (-45℃) kunye ne-hydrogen ephantsi esasazekayo. Iimpawu zayo zenza le mveliso ifaneleke kwiintsimbi ze-alloy eziphantsi, iintsimbi ze-carbon eziphakathi, iipleyiti zentsimbi enzima, iintsimbi ezibunjiweyo, intsimbi ye-aluminium ebuleweyo ye-LPG kwaye ngakumbi ukuwelda kweentsimbi ezine-weldability ephantsi.

Amanqaku malunga nokusetyenziswa:
1. Ngaphandle kokuba imeko yokugcina ikhuselekile kwaye ukupakisha akonakalanga, sicebisa kakhulu ukuba omise ii-electrodes kwi-350-400℃ kangangeyure eli-1-2 ngaphambi kokuba uzisebenzise.
2. Sebenzisa indlela yokuthintela ukuvuthuza kwemingxuma kwi-arc.
3. Kucetyiswa kakhulu ukugcina ubude obufutshane be-arc ukuze kuthintelwe ukufuma.
