Product Description

Properties of Electrode:

Low Hydrogen Electrodes provide fill freeze (out-of-place) or fast fill (high-dismissal) attributes and are developed to produce sound binds of X-ray grade with exceptional impact/notch features and high ductility.

Some less hydrogen stick rods possess a -1 suffix in AWS category. This suffix shows that the stick rod caters the needs for enhanced toughness.
Joining consumables can be categorized with an elective diffusive hydrogen designators, which comprises H4, H8 and H16 specification. The 'H' and relative digits depicts milliliters of diffusive hydrogen per 100 grams of fuse metal. For instance, a specification of H4 shows 4mL of diffusive hydrogen by 100 grams of bind deposit. While the 'R' designation for a rod illustrate that it consists moisture-resistant covering. To authorize for 'R' specification, rods that have been evicted from purely opened packs or have be renovated are revealed to 80% correspond dampness and temperature for 9 hours of 80°F.

Damp content following this outlook can not be further than 0.4 load percent. Even a less quantity of humidity over this stage can affect weld permeable and other flaws.
Whereas low hydrogen rods are suitably should operate on DCEP polarity (particularly, if the extent is 5/32" or less) and also on AC polarity. Indeed, some EXX18 rods are created specially for AC polarity like  7018 AC pole rode from Lincoln Electric.

Our years of knowledge and experience in this domain have supported our firm to manufacturer, export and supply Low Hydrogen Electrode. This electrode is suitable for welding of the metal products for attaining the superior-quality repairing and fabrication works.
