MasterWeld Ni1 (ER80S-Ni1) is a copper coated low alloy TIG welding wire alloyed with nominally 1%Ni for improved toughness. Actual Ni content is kept below 1% to ensure conformance with NACE MR0175.

MasterWeld Ni1 is for welding of CMn steels with yield stress of 450MPa or where good toughness is required down to –50°C, such as:

ASTM A333 & A334 Grade 6

A350 Grades LF2 & LF5

A352 Grades LCB & LCC (cast)

API 5L X65

BS 4360 Grades 43E, 50E, 55C, 55EE, 55F


Welding of high strength steels

For welding higher strength steel structures where PWHT is impracticable so that welds must possess an appropriate degree of toughness and crack resistance.

Ideal for welding of Weathering Steels

The addition of about 1%Ni promotes micro structural refinement, with improved tolerance to procedural variations compared to plain CMn weld metal. Nickel also increases atmospheric weathering resistance and improves electrochemical balance between weld and base metal, thus minimizing preferential weld area corrosion in marine environments. For offshore oilfield sour service, a maximum of 1.0%Ni is commonly required (NACE MR0175).

Also recommended where design requirements specify toughness testing of higher strength low alloy steel welds down to –50°C eg. offshore construction, pipelines and pressure vessels.
