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 […]

Calculating Weld Metal Requirements by Hand

When you don't have your Procedure Handbook Tables

If you need calculate weld metal requirements and you do not have The Procedure Handbook of Arc Welding handy you can do this by hand by using simple geometry. What you need to do is find the volume of weld needed in cubic inches. A fillet weld with a flat face forms a right triangle. […]

Calculating Weight of Weld Metal Required

Estimate pounds of welding electrode necessary to complete a job

Calculating weld metal requirements seems complicated but for the majority of applications it should not be. Short of having a computer program that calculates this for you, the easiest way is to use the tables found in The Procedure Handbook of Arc Welding. Table 12-1 provides data to calculate weight of weld metal required per […]

How To Know If You Are Wasting Shielding Gas

Most manufacturing facilities use  1.5 to 3 times as much shielding gas as they should.  The reasons for this can be found in a previous post: Control Your Shielding Gas Usage. Before doing all the checks to see if you have leaks or other problems there is a simple way to get an idea of whether or not […]

Deposition Rate by Wire Type

A common question in the field is which wire type will provide the best deposition rate.  In one of our earlier posts “Calculating Deposition Rate for Solid Wires” we discussed deposition rates strictly for solid wires.   Here we will talk about deposition rates across wire types – mainly solid wire, metal-cored wire and flux-cored wire.   […]

Calculating Deposition Rate for Solid Wires

A common question that is asked when manufacturers are trying to determine costs associated with welding is: How many pounds of wire can I deposit per hour? Or, how many pounds of wire can I deposit at a specific amperage or wire feed speed?   There are charts to help you determine this, but unless you […]
