Premium 7018 Welding Electrode
Premium 7018 Welding Electrode
Product Code : 28
Product Description

Classification :

  • IS : 814 - 2004 : EB 5426 H3 JX
  • AWS/A 5.1 : E 7018

Description :

A heavy coated low hydrogen, iron powder type electrode ideally suited for producing tough and ductile welds of radiographic quality in boilers, pressure vessels and heavy structures subjected to dynamic-loading. The smooth, soft arc, easy slag control, all positional welding, low spotter and excellent slag release provide maximum weldor-appeal. The electrode has a metal recovery of minimum 110%. GM 18 has very good impact values down to minus 30oC. Typical hydrogen content is 3 ml/100 gms of weld deposit.

Applications:

  • Boilers : Earth moving machinery
  • Pressure Vessels : Storage tanks
  • Pipe lines : Penstocks
