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.

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.

Continuous improvement: Do you have a handle on flow

May 23, 2016

By:

Manufacturing is all about flow, both of physical products and information. You can plan for good flow. But if you let it evolve on its own, you will be dealing with the waste and efficiency that evolution creates.

Product design

May 23, 2016

By:

Waiting for a callback to discuss a major design change is one thing; but waiting hours just to see if a hole can be moved a little farther from the bend radius—that’s something else. One industry project, iFAB, aims to make design for manufacturability far more efficient.

5 steps to lean assembly in the job shop

May 9, 2016

By:

Many think cellular assembly isn’t applicable to the job shop, but in fact, creating cells in custom manufacturing is nothing new. For shops that carefully identify product or process families, cellular assembly can help increase throughput dramatically.

Which press brake is best?

May 9, 2016

By:

No press brake is best for every application, but you can find a press brake that’s best for you. To find that press brake, you need to match what’s available—hydraulic, hybrid, electric, mechanical, and other styles, along with the tooling—with what your operation needs.

Maintaining good cut quality when using an abrasive saw

May 2, 2016

By:

A fabricator that can find the right abrasive wheel for the job, can figure out the right cutting speed and downfeed rate, and can find the right saw with enough power likely doesn’t have to worry about poor-quality cuts while abrasive cutting.

Do you manage scrap properly?

May 2, 2016

By:

A metal fabricator checks incoming raw material before signing off on it. Doesn't it make sense to pay as much attention to the material leaving the facility? The potential return on the effort suggests "yes."
