Practical Welding Today January/February 2005
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.
Metallurgy Matters: Thermal cycles, the HAZ, and the strength of martensite
- By Bob Capudean
- Jan 18, 2016
- Metals/Materials
- Article
Last time we looked at how welding heat influences the heat-affected zone (HAZ) of metals strengthened by three typical hardening processes: solid-solution hardening, cold working, and precipitation hardening. That leaves one critical strengthening process to consider: transformation (martensite)...

- Arc Welding
- Article
Q: I would like to know if a wire-feed welding machine can double as a modest-amperage DC shielded metal arc welding (SMAW) machine if I attach an electrode holder to the output. I have been told that aluminum welding works well and is convenient using SMAW and DC. I have the aluminum roller kit...

- Arc Welding
- Article
Plasma arc welding (PAW) uses plasma, a gas that has been heated to a high temperature and ionized. The plasma becomes electrically conductive, transferring an electric arc to the workpiece through a small orifice.
Simplifying shielding gas selection
