9018 Welding Rod Uses

The 70 corresponds to a tensile strength of up to 79 900 pounds per inch psi.

9018 welding rod uses. For high temperature applications such as in the electrical power industry the high carbon 308h electrode provides better creep resistance than does 308l. The principal application of atom arc 9018 cm electrodes is for welding 2 1 2 cr 1 mo steels commonly found in pressure vessels heat exchangers pipings and other related components. All except the 6010 can be used with ac and dc currents. My understanding is 8918 and 9018 are also low hydrogen rods.

In certain cases namely smaw and stick welders the wires actually melt becoming part of the weld itself. Welding consumables catalog ı 43 stick smaw electrode excalibur 9018 b3 mr welding positions typical applications all except vertical down 2 25 chromium 1 molybdenum steels power generation petrochemical pressure vessels process piping designed for all position welding of 2 25 chromium 1 molybdenum low alloy steels premium arc. Atom arc 9018 electrodes are used for attachment welds on t 1 hy 80 and hy 90 steels and other high tensile quenched and tempered steels. 308l including er308lsi is predominately used on austenitic stainless steels such as types 301 302 304 305 and cast alloys cf 8 and cf 3.

The american welding society does not provide specification for carbon welding electrodes but there is a military specification no. But can be used on low strength steel like any rod with hydrogen. All four of the welding rods which we ve looked at are all position rods which offers great versatility. The welding rod is the piece of wire connected to the welding machine.

Can only be used on high strength steel if kept water vaper free but can be used on low strength steel regardless. Mil e 17777c entitled electrodes cutting and welding carbon. When should i use 308l 309l or 316l filler metal. The tungsten electrode is defined as a non filler metal electrode used in arc welding or cutting made principally of tungsten.

A current is fed through this wire which helps to join two pieces of metal together firmly.
