Try to laser weld two pieces of clear plastic together and they may not remain clear for long. The carbon black and other opaque additives that make laser welding of clear materials possible in the ...

The Weld Bead Inspection (WBI) Tool provides peace of mind for piping systems in the microelectronics, chemical processing, life science, and energy sectors, by assessing the quality of infrared-weld ...

Last month we looked at the MIG process, which is definitely the most popular type of welding used for classic trucks. This month we'll explore TIG welding, which many people consider the premiere ...

Last month, we presented the basics on setting up a TIG welder as the groundwork for the next few write-ups on actually making things with TIG welding. These TIG welding techniques aren't difficult—it ...

In the manufacture of heat exchanger components for aircraft, it was found that using the pulsed TIG method to weld the inlet and return manifolds was giving excessive porosity. Consequently an ...

Dynabrade's 4 1/2-in.-diameter depressed-center wheel grinder features a 12,000-rpm, 1-hp air motor for cleaning metal before welding and removing weld beads afterwards. This grinder has a safetylock ...

To grind or not to grind? What a question! It all depends on what you’re really trying to show, and in the case of welded joints, I often want to prove the integrity of the weld. My ground-back piece ...

The present research has been done to study the effect of different independent input process parameters on the desired responses in the submerged arc welding process. Half factorial technique has ...
