Advanced GMAW processes help in welding P91

May 26, 2016

By: ,

Alloy P91 has excellent high-temperature strength and creep resistance, making it a favored alloy for piping systems for power boilers and other applications that work at elevated temperatures and pressures. The conventional welding processes, gas tungsten arc welding and shielded metal arc welding, do a good job on P91, but modified gas metal arc welding (GMAW) processes and flux-cored arc welding (FCAW) have deposition rates three to four times faster.

Lockset manufacturer gets handle on scrap to boost productivity

May 25, 2016

By:

When you stamp 2.2 million pieces a day in the manufacture of lockset and doorset assemblies— 550 million stampings a year—smooth, speedy operation is your goal and bottlenecks and obstructions to productivity are your targets. Kwikset developed a unique way to handle scrap that removed a bottleneck and increased output.

Getting to know more about the metal you are forming

May 25, 2016

By:

An estimated 3,500 different grades of steel currently exist, with about 75 percent of them developed in the past 20 years. And more than 500 sheet aluminum alloys are registered with the Aluminum Association. Each of these materials grades has a different chemistry and different tensile properties...

Industrial dust collection goes modular

May 24, 2016

By:

Large-scale dust and fume collection can be somewhat inflexible. A fabricator moving, adding, or removing a few work centers can throw off the airflow balance and make the entire system less effective. A new technology aims to change this.

Don't lose track of the latest design updates

May 23, 2016

By:

The goal of forward-thinking fabrication shops is to be closely involved in a customer's supply chain, where perhaps it participates in part designs and design for manufacturability activities. If a shop is to be an active supply chain partner, it needs to be able to stay on top of engineering change orders and part design discussion. Cloud-based product life cycle management software can help.
