NCPWB Technical Bulletin: When To Use E6010 Welding Electrodes
The E6010 electrode is a wire encased in cellulose held together with salts and minerals. These electrodes penetrate better than low-hydrogen electrodes like E7018 when making root passes, making it easier to make a good root pass. However, E6010 introduces hydrogen into the weld creating a risk of cracking, and this article shows when its use should be limited.

Piping codes are standard industry practice, and failure to agree on the one that applies to your work can result in ugly disputes with customers. Customer specifications can have inspection requirements that can result in repairs to welds that you did not plan for. Welders can make welds that put your business at risk. This article highlights what you can do to avoid these risks.

NCPWB Technical Bulletin: What You Should Understand About GMAW (MIG) & FCAW Welding
While there is a lot of buzz about modern waveform controlled power sources and how they make it easier for a welder to make the root pass, the basics of MIG welding have not changed. This article describes the technical aspects of GMAW, explains how the metal gets from the wire to the workpiece (transfer modes), and highlights what contractors need to pay attention to when bringing the process into their shop or field fabrication site.

NCPWB Technical Bulletin: The 37-1/2 Bevel
The 37-1/2°± 2-1/2° bevel is the normal bevel angle to find on piping fittings and flanges and in many specifications and standards. Where did such a weird angle originate?

MCAA’s Virtual Trade Show connects our contractor members with the members of MCAA’s Manufacturer/Supplier Council.
Last week, the construction industry came together at the 2025 Safety & Health Conference, where over 500 safety and health professionals from the Mechanical Contractors Association of America (MCAA), the Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA), and The Association of Union Contractors (TAUC) reaffirmed their commitment to advancing safety and health across the trades.

The National Certified Pipe Welding Bureau (NCPWB) has released a new Technical Bulletin highlighting when to use E6010 welding electrodes, and when their use should be limited. While E6010 electrodes make it easier to make a good root pass, they introduce hydrogen into the weld creating a risk of cracking. The bulletin explains how best to mitigate this issue so that every weld is a quality weld.
