Proper Storage of Welding Consumables

How to store stick electrodes, and mig, flux-cored and metal-cored wires

Proper storage of both opened and unopened packages of welding consumables is crucial. It should avoid quality issues such as porosity, excessive slag fluidity, rough weld surface, difficult slag removal and more importantly, elevated levels of diffusible hydrogen which can lead to cracking. Adequate storage, handling and re-conditioning of electrodes vary according to type.  The […]

How Many Inches Of Mig Wire Per Pound

Easily calculate number of inches of wire per package size for any wire diameter

Have you ever wondered, or have you ever been asked how many inches of wire are in one pound of filler metal?  You may have been asked something like: “How many inches of wire are there in a 25LB spool of .035” ER70S-6 mig wire?”  Typically, this questions is asked when someone is trying to […]

Storing and Re-drying Low Hydrogen Electrodes

Low hydrogen stick electrodes come in hermetically sealed cans to prevent moisture pick up. However, once the package is open the coating can be above permissible levels of moisture within a few hours. The rate of moisture pickup depends on several factors including but not limited to relative humidity, electrode coating characteristics, and storage locations. […]

Mig Welding With S3 vs S6 Wire

Is ER70S-3 even necessary anymore?

One of the most frequently asked questions is if there is a valid reason to use an ER70S-3 (S3) mig wire versus the more commonly used ER70S-6 (S6) wire.    Both wires belong to AWS Specification A5.18 and can be used interchangeably in most applications because they provide almost identical mechanical properties.  There is subtle difference between the two […]

Deposition Rates for Stick Electrodes

Although most people may believe that stick welding is antiquated and a bone-headed choice for a welding process, this is simply not true. It is true that in production welding, especially in a controlled environment like a fabrication shop, the use of stick welding is typically a big mistake due to its low efficiency, extremely […]

Welding Cast Iron

Cast iron is not impossible to weld, although many that attempt to do so end up with a cracked weldment. The reason welding cast iron is a big challenge is that it contains up to 4% carbon.  This is an insane amount, considering that any material with a carbon content above 0.30%  is already considered […]

Short-arc vs Globular Transfer in GMAW

What is the difference between globular and short-circuit transfer? Short-circuit is a mode of transfer in GMAW in which metal is transferred from the electrode to the weld pool via a series of electrical short circuits. When the electrode (wire) touches the base material a short occurs and the arc goes out.  At this point […]
