Why Are Fillet Break Tests Done for Welder Qualifications

When qualifying a welding procedure specification (WPS) for  fillet welds per Clause 4 of AWS D1.1 Structural Welding Code you must only perform a single test.  You must do macroetches in three locations as shown below. It is assumed that if we can show root fusion at these three locations that our welding procedure is […]

The Best Piece of Equipment to Reduce Welding Costs

Many fabricators spend thousands of dollars in new welding equipment every year.  They look for the latest and greatest technology that will allow them to reduce manufacturing costs.  We have seen some of our customers justify the purchase of robots and other types of advanced welding equipment relatively easily.  Some pieces of equipment pay for […]

Can Pulse Really Solve All Your Welding Problems?

Competition amongst manufacturers of welding machines is a wonderful thing.  Companies like Miller, Fronius, OTC, Lincoln Electric, and many others are continually improving their equipment, making it more user-friendly and at a lower cost.  We as users benefit from this.  However, this has brought about a significant problem, a huge epidemic. And that is the […]

9 Steps to Develop a Repair Welding Procedure

Some repairs, whether it is repairing a failed weldment or repairing a crack in a casting, may easily be done by simply grinding out the crack and applying more weld.  Other repairs, however; are more complicated.  Or at least they should be. Just last week a customer contacted us asking for help in developing a […]

The Reason Behind Minimum Fillet Weld Sizes

It's not what you think

Have you ever noticed that there are design rules that prohibit sizing a fillet weld below a certain size for a given thickness of material? If you look at AWS D1.1/D1.1M:2015 Structural Welding Code (Steel) you can find this on Table 5.7.   If you happen to own a copy of AISC 360-16 Specification for Structural […]

Modes of Metal Transfer: Pulse

Pulsed spray refers to a GMAW mode of transfer in which metal droplets are transferred through the arc with changes in amperage produced by the power source.  The power source provides a pulsing peak current that raises the amperage above the transition current and allows for axial spray transfer.  This peak current is only applied […]

Modes of Metal Transfer: Spray

Spray is a mode of metal transfer in which a fine spray of metal droplets are projected axially from the tip of the electrode to the work.  These droplets are smaller in diameter than the electrode.  This mode of transfer is characterized by high wire feed speeds (high amperage), high voltage and consequently high heat […]

Can You Read Welding Symbols?

Take the Welding Symbols Test to find out

Welding symbols are the universal language of the welding industry. They are used to communicate vital information regarding the details of a weld including: Joint details Weld size and length Weld sequence Contour finish Location Process Required inspection methods Penetration requirements Etc. Yet this important language is not understood by the vast majority of those […]
