FCAW or Flux Cored Arc Welding-

So basically the assumption had always been that FCAW procedure had always been done without the need for gas. Had just learned today according from individual at professional welding shop that shielding gas can indeed be used in conjunction with Flux Cored Arc Welding.

Apparently, you can use gas such as CO2 and Argon with the method much like with MIG welding. Some welding machines have different setups with regards to what type of welding that is required. For instance you can have a machine set up for MIG/TIG, MIG/FCAW, SMAW, etc.

FCAW operates on the same basic procedure that MIG/GMAW uses, and most people will claim that it is relatively easy to use compared to stick or TIG. So now going into a little more detail for FCAW, we will now look at a few of the different positions that are used with this welding method.

One of the biggest advantages that FCAW has over multiple other forms of welding is its high deposition rate of metal. This is truly one of the more important reasons as to why many fabrication shops and ship building industries favor FCAW immensely

- Flat: obviously one of the easiest positions to weld in as well as usually the position that many first time welders will begin. For the author, have found one of the best ways to learn for anyone who is beginning FCAW or GMAW is to be comfortable as to be able to manipulate the torch better.

Flat position or 1G/1F will offer the majority of folks, especially the beginners, the most comfort.

Horizontal: 2G/2F

Vertical: 3G/3F

For those who have struggled with stick welding in the vertical position and have not FCAW/GMAW welded before, this will certainly be a lot easier. Of course FCAW in this position tends to be easier due to the fact that you only have to worry about keeping the gun steady and watching the puddle.

With stick welding, you do this plus have to keep feeding the electrode in manually as you move along the puddle. It will take a few times to practice but eventually it will become really easy to do.

Introduction to Operations

-When welding with FCAW equipment, it is also particular import to pay attention to the torch tip during welding operation. Most of the time spatter will gum up the nozzle tip causing obstruction for the gas (if you are set up for FCAW-G or GMAW).

-Depending on whether or not you might be new to FCAW or GMAW welding, it isn't always possible to weld in a comfortable position. Case in point, the welding instructor for the author was a retired welder of 40+ years at a local shipyard. He made mention that much of the FCAW welding was done out of position (e.g. welding with a mirror, on his back etc.)


  1. Our trampoline just broke and my husband is constantly working so I have had to learn some welding in red deer so I can fix it on my own! It's so hard for me! I'm trying to gather as much information as I can about it though! Thanks so much for sharing!

  2. I have been really impressed by going through this awesome blog.metal fab

  3. Great insights. The process of manufacture of welding electrodes consists of several steps, each of which must be executed with high precision. The manufacturing process is automated with a variety of welding electrode making machines available in the market today.

  4. im fixin to have to take a nomenclature test for a fcaw job at caterpillar, what the heck is gonna be on that test and where online can i study for it ? can anyone help ??????

  5. I was just learning that the blue light that come off the welder can hurt your eyes really bad if you look at it. I think something that is also very important with welding is safety. One part of safety to me is getting the right equipment as well. http://www.burnback.com.au

  6. Actually these work is very risky so we should know about safety as well as safety tools. All of our organs are very important so we should not take any risk before protect us. I have a site which discuss about weldinghelmethq. Please visit this site to know more.
