Practical Welding Today March/April 2017
The Welder, formerly known as Practical Welding Today, is a showcase of the real people who make the products we use and work with every day. This magazine has served the welding community in North America well for more than 20 years.
Consumables Corner: Choosing the right filler metal for A513 HSLA 70 steel
- By Nino Mascalco, Rob Koltz, and Steve Sigler
- Mar 27, 2017
- Consumables
- Article
Q: We have a job coming up involving hand rails, stairs, and tables for outdoor use. The engineers chose A513 HSLA 70 steel because it is thin and saves on weight. In the past we used A500 and welded it with an E70 filler metal. Because we are now using a material that is thinner and higher in...

More than 80 percent of the cost for a manual weld lies in the labor required to perform it. By choosing the right welding transfer mode and wire for gas metal arc welding (GMAW), you can reduce your overall cost and improve productivity and efficiency.
Which filler metal should you choose?
- By Kevin Trick

- Consumables
- Article
6XXX series is a common base material used in aluminum applications and, generally speaking, its best filler metal match is either the 4XXX or 5XXX series. The filler metal you choose depends on how the finished weld will be used. Will it be exposed to sustained elevated temperatures? Are strength, ductility, and toughness key requirements? Determine which properties are most important for the completed weld and select the filler metal according to those priorities.

- Article
Getting to the root cause of wire feeding problems in aluminum GMAW can be a head-scratcher, particularly if you are more familiar with welding steel. When feeding problems crop up, the solution can be as simple as understanding five key components. Familiarizing yourself with these components and knowing how to adjust them for aluminum welding can help the process run smoothly.
