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?

NCPWB Technical Bulletin: The Difference Between NCPWB WPSs and AWS Standard Welding Procedures

This bulletin explains how the National Certified Pipe Welding Bureau (NCPWB) Welding Procedure Specifications (WPSs) differ from the American Welding Society (AWS) Standard Welding Procedures in both application and adoption.

NCPWB Technical Bulletin: Qualification of Welding Operators for Orbital TIG Welding

There is occasional confusion among NCPWB members who use orbital pipe and tube welding machines when it comes to determining just what is required to qualify a welding operator and how to properly complete the QW-484 form for welding operators. This bulletin clarifies the difference between a welder and a welding operator and provides sample welder qualification test records for welding operators using automatic and machine welding.

Welding professionals need to understand the types of defects found in weldments and how they appear in a radiograph to ensure the projects they deliver will not fail. NCPWB’s Radiograph Interpretation Technical Resource provides both written and visual examples of discontinuities to simplify the process. It’s just one of MCAA’s educational resources that are free to MCAA members as a benefit of membership.

A Federal Trade Commission (FTC) rule banning non-compete clauses is set to go into effect on September 4, 2024. Under the rule, non-competes are broadly defined as any arrangement that prohibits, penalizes, or functionally prevents a worker from getting a new job or starting a business after leaving their employment, even if the agreements are not labelled as non-competes. In short, the rule bans employers from entering into non-competes with workers covered by the rule. It also imposes an obligation on businesses to notify former employees and contractors with whom they previously entered into non-competes, that these agreements are now unenforceable. There is an exception for agreements with senior executives related to the bona fide sale of a business and for situations where a dispute arose about whether the non-compete was breached before the effective date of this rule.
