E7016 Welding Rod

E7016 welding rod is a low hydrogen electrode having similar characteristic of E7015 however E7016 can be used with AC and DCEP Polarity.

E7016 welding rod

E7016 rod gives a crack resistant weld compared to E7018 rod on thick material welding and useful for welding on heavy weld seams or restrained welding joints to avert cracking.

7016 Welding Rod Polarity

E7016 Welding Rod Polarity is AC and DCEP (Electrode positive, or Reverse polarity).

E67016 Welding Rod uses

This low hydrogen Welding rod is used for welding applications for:

  • Welding of low carbon to medium carbon steel.
  • Welding barrier weld layer before hard facing.
  • Welding of ASTM A515, 516, 570, 572, 607 and 668 grades.
  • High cracking resistance for welding thick materials.
  • E7016 gives a ductile weld that is beneficial for API pipelines jobs where hardness control is required.

Storage and baking of E7016 Welding Electrode

Being a low hydrogen electrode, E7016 requires baking/ drying before use. The recommended drying or baking temperature for E7016 rod as per AWS A5.1, Table 1.3 is 500- 800°F (260- 425°C) for 1- 2 hours.

Baked or dried electrode shall be kept in portable holding oven at a temperature of 50- 250°F (30- 140°C) during use. Unused electrodes shall be returned back to stationary holding ovens.

E7016 Welding Rod amperage

E7016 welding electrode amperage depend on the electrode diameter. 3/32” rod is good with 75- 110 ampere, 1/8” with 100- 150 ampere and 5/32” with 150 to 190 ampere current.
