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.

Arc Welding 101: Defining a fillet weld with D1.1

May 13, 2016

By:

Q: I'm auditing a fab shop and have a question regarding the AWS D1.1 code. The shop is referring to the corner joints in the plates encompassing the columns as fillet welds, yet there is no faying surface. D1.1 says a fillet can have up to 3/16-in. misalignment (with certain stipulations), which...

Aluminum Workshop: The perks of a push-pull gun for GMAW

May 12, 2016

By:

Q: I will be getting into aluminum welding much more than I have in the past. I want to buy a new set of equipment for gas metal arc welding (GMAW) and I’ve already picked out the power supply and feeder. Should I buy a push-pull gun or stick with the simpler and less expensive push-only gun? A:...
