Pulsed GTAW for stainless steel
Figure 1
Proper fit-up and good control of the welding parameters go hand-in-hand in producing successful fusion with minimal distortion. A poor fit-up requires more weld metal to fill the gaps. More metal means more heat, which leads to more distortion.
Some welders swear that... Read more...

Robotic GTAW or GMAW: No longer a clear-cut choice
Figure 1 Technology advancements have made GTAW easier to automate. Photo courtesy of The Lincoln Electric Co. Robotic systems manufacturers and integrators have a confession when it comes to TIG, or gas tungsten arc welding: They've sometimes steered people away from it. "I've worked... Read more...

GTAW la delgada línea
Lo delgado está de moda—es decir, para materiales.
Por los estrictos requerimientos de peso, espacio y diseño en sectores que van desde el procesado de tubos hasta el espacio aéreo, más aplicaciones requieren con frecuencia materiales como acero inoxidable, acero suave y aluminio de ¼ de... Read more...

Welding for all seasons
Tom Young knows people. He knows Dan Pastorini, onetime Houston Oilers quarterback and today a race car owner and driver for the SCCA Pro SPEED World Challenge circuit. He also knows Richard Fielden, an artist whose public sculptures and other works dot the Houston metro area. They both know... Read more...

TIG for titanium tubing
Titanium is 45 percent lighter than steel, 60 percent heavier than aluminum, and more than three times stronger than either of them. While it is much more expensive than many other metals, it has greater corrosion resistance, lower life-cycle costs, longer service life, and drastically lower... Read more...

The root causes of weld defects
Weld defects happen for a host of reasons. Air may creep into the weldment to cause porosity. The wrong amount of heat can cause cracking. Bad welding technique can cause undercuts or incomplete penetrations of one kind or another. Various factors contribute to weld problems, but many lead... Read more...

GTAW the thin line
Thin is in—for materials, that is. Because of stringent weight, space, and design requirements in sectors ranging from tube processing to aerospace, more applications frequently call for materials such as stainless steel, mild steel, and aluminum inch and thinner. And often these... Read more...

Learning TIG
Photo courtesy of The Lincoln Electric Company Gas tungsten arc welding (GTAW), which used to be called heliarc, is referred to by most welders in the shop and field as TIG. In the field, TIG applications include welding stainless in the food industry; stainless, aluminum, titanium, and... Read more...

Guidelines for tungsten electrodes
Tungsten is a rare metallic element used for manufacturing gas tungsten arc welding (GTAW) electrodes. The GTAW process relies on tungsten's hardness and high-temperature resistance to carry the welding current to the arc. Tungsten has the highest melting point of any metal, 3,410 degrees...

The shocking truth about welding
Photo courtesy of TWI I was thinking about how my articles always begin with something stupid or embarrassing I've done and what a shame it is that I can remember so many stories to relate. I'm going to mix things up this time and begin with a stupid story about a former... Read more...

TIG welding - an overview
As I've said before, I like to begin my articles by relating a personal dumb but funny learning experience. Why do I do this, you might ask? Because I'm not afraid to admit I make mistakes; after all, I'm human. I've been taught by, worked for, and even been friends with a few people who... Read more...
