Package		20kg/Carton

EASYARC™ 7016 is a low-hydrogen type electrode for all-position welding of mild and low alloy steels. The easily controlled arc of EASYARC™ 7016 makes it easy to use on either AC or DC polarity. EASYARC™ 7016 offers excellent mechanical properties and crack resistance. It is also easy to strike and restrike.

ADVANTAGE LINCOLN

High deposition rates
Easy slag removal
Excellent crack resistance and X-ray performance
Flat or slightly convex beads have distinct ripples with little spatter
Manufactured under a quality system certified to ISO9001 requirements
Available in PERMAPACK™ (Vacuum Sealed)

REDRYING

All controlled hydrogen electrodes will perform optimally when they are dry. Unopened Lincoln PERMAPACK's provide excellent protection against moisture pick-up in good storage conditions. Should re-drying be necessary, remove electrodes from the packet / container and spread thinly and evenly on racks in a ventilated oven. For electrodes that have had a short or mild exposure to the atmosphere then re-drying at 572°F(300°C) for 1 hour will be sufficient. For electrodes that have been exposed to longer or more aggressive conditions or for critical work re-drying at 572-662°F (300- 350°C) for 1-2 hours is recommended. After re-drying electrodes should be stored in a hot box.

Typical Application

EASYARC™ 7016 is a multi-purpose electrode with excellent operator appeal. EASYARC™ 7016 can be used for general construction welding applications such as bridges, buildings, ship building and pressure vessels. EASYARC™ 7016 can also be used for the construction or repair of earth moving or farm equipment. EASYARC™ 7016 is excellent for the welding of medium carbon steel, low alloy, and thick plate such as (ASTM A131) Grade A, B, D and E ship plates.

Conformance

AWS/ASME A5.1/SFA5.1 E7016

Guidelines for Use

All water, rust and oil should be completely removed from base material to prevent cracking and blowholes.
For improved impact properties, avoid use of excessive amperage levels.
Backstep method should be applied to prevent blowholes and pits during arc start.
Arc length should be kept as short as possible during welding.
If weaving is required, the width should not exceed 3x the diameter of the electrode.
