Advantages of SAW (Submerged Arc Welding):

-It has a high deposition rate and it can penetrate the weld deeply.

-When you have designed a good process and you have control over what you are doing you can be sure that you get a strong weld.

-You can actually do this with thin sheets of steel and they can be done at a higher speed.

-There are very minimal fumes or arc lights which makes this a safer process.

-You can do this indoors or outdoors.

-You don't have a lot of distortion.

-You don't get any spatter on the weld because the arc is always under the blanket of flux.

-As with any technique there are a few limitations with the SAW method that include:

-You are limited to only a few positions that you can use this within.

-You can only use steel, stainless steel or a few nickel based metals.

-The flux handling systems can be more complex and difficult to use.

-Slag is a problem in a couple of ways: you can get residue from it that may cause some issues with your health or with safety and it will require a complicated slag removal system.
