Electrodes - PROMAX 16LH Low-Hydrogen

Low hydrogen E7016 series stick welding rods for mild or high strength steels, where higher joint strength is required, such as components subject to higher load stress and strain. Also used as a buffer layer prior to hard facing. Smooth arc, easy-striking, with easy slag removal. Supplied in a 1kg re-usable convenience pack to keep electrodes in good condition, available in 2.5mm, 3.2mm & 4.0mm. AWS A5.1 E7016 H8 & AS/NZS 4855: B E4916 A U H10 classifications.

KEY FEATURES

  • Hydrogen controlled, for welding mild & high-strength (carbon-manganese) steels up to 510MPa
  • User Friendly: Very Smooth & Stable Arc, Easy Striking, Low Spatter, Easy Slag Removal
  • All-Positional (except for vertical down) & excellent weld appearance
  • 1kg re-usable pack keeps electrodes in good condition

 

1KG RE-USABLE PLASTIC PACKS - REDUCES WASTE & MOISTURE EXPOSURE

  • Sealed packs keep moisture out, right up to the point of use
  • Smaller pack size reduces waste & minimises the time/period of exposure to atmospheric moisture
  • Re-usable packs keep unused rods in good condition

 

WHY IS IT IMPORTANT TO AVOID MOISTURE ?

  • Air contains moisture (humidity) and any electrode exposed to air will absorb moisture
  • This increases hydrogen levels in the electrode (water 'H2O' contains hydrogen 'H')
  • Increased hydrogen compromises the strength & mechanical properties of the weld
  • Moisture can also negatively affect the arc characteristics of the electrode

 

APPLICATION INFO:

  • Mining maintenance & fabrication
  • Structural steel & site welding
  • Rural maintenance
  • Pipe construction
  • Boilers & pressure vessels
  • Build up or buffer layer prior to hard facing
  • Single-sided weld joints

 

OPERATING DATA

  • Suitable for all DC or AC welding machines
  • All-positional, except for vertical-down
  • Polarity: AC± or DC±

  • Suitable for use with most inverter welding machines, however older transformer machines may not have sufficient OCV (open circuit voltage)

 

CLASSIFICATIONS:

  • AWS A5.1 E7016 H8
  • AS/NZS 4855: B E4916 A U H10
  • EN ISO 2560-A: E 38 2B H10

 

 TYPICAL MECHANICAL PROPERTIES:

  • Yield Strength: 510 MPa
  • Tensile Strength: 590 MPa
  • Elongation: 26%
  • Impact Strength (CVN): 100J @ -20c / 70J @ -30c

 
FAQs:

Q: Does the sealed pack avoid the need for pre-drying electrodes in an oven?
A: This depends on the application. At the point of opening a sealed pack, 16LH electrodes will almost certainly contain less moisture than electrodes that are not sealed - however electrodes ovens should still be used in critical situations or when specified in the weld procedure.

Q: How many rods per pack/KG ?
2.6mm = approx. 50 rods per KG
3.2mm = approx. 33 rods per KG
