It was a fun night for me at the monthly American Welding Society — San Diego Section meeting.  This night’s topic?  Induction heating with a system unlike anything you’ve ever seen before.

Gone are the days of waiting hours and hours for your length of pipe to warm up to the right temperature –

Miller has just released the new ProHeat 35 Induction Heating System, which works by inducing heat electromagnetically, rather than via a conductor, thus saving the operator incredible amounts of time and energy.

Simply wrap the induction coils around whatever piece of metal you’re working on, and in just a few minutes, you’re ready to go!

This picture was taken looking inside the length of pipe that was being heated up by the ProHeat 35 — you can’t see it here, but that tube was glowing red hot on the inside!

And even better, when I tried touching the coils wrapped around it?
Cold as ice! This product is simply amazing!

But perhaps the best part about this whole new system is that you don’t even have to buy it! Red-D-Arc will rent out one of their machines to you for as long as you need!

If you’ve ever had any questions with regards to finding the proper filler metal for welding aluminum (or aluminium, as everyone else calls it), then look no further!  Tony Anderson from the AWS has exactly what you need:

Finding an ally alloy

6 variables that affect aluminum filler alloy selection

Choosing the best filler metal for aluminum welding involves taking into account the operating conditions of the finished welded component as well as six important variables that can affect the operating condition.

Editor’s Note: This article is adapted from Tony Anderson’s presentation for the Aluminum Association Conference, May 5-6, 2009, Toronto, by the American Welding Society.

Filler alloy selection for welding aluminum is an essential part of the development and qualification of a suitable weld procedure specification (WPS). Choosing the most appropriate filler alloy for welding aluminum is based on the operating conditions of the finished welded component and a number of variables.

When selecting a filler alloy for welding aluminum, it’s a good idea to compare the performance of each filler alloy against each of the six variables: ease of welding, strength of the welded joint, ductility, corrosion resistance, sustained-temperature service, and postweld heat treatment.
