Guys I am really struggling to run beads on aluminum. Ive been practicing on .125 . I can run a perfect bead no filler , even on the edge. The settings reacts exactly how all the videos say they should. The white band from the cleaning , Foot pedal responds decent, It happens just like the videos, ...

I've been asked to weld some copper bus bars together to lengthen them. The bars are about 1/4" thick and apparently pure copper. Either way, I can find out what exactly they are made of. Can I TIG weld copper just like aluminum? If I can, what rod, anything particular I need to be aware of? P...

I have access to both tig & mig Miller welders 300 amp, the plate will need to be flat when done. pic attached I could weld the plate to the 8 x 8 tube first? Strongly recommend against welding a ROUND member directly to a FLAT plate. You will not achieve adequate fusion in the interface betwee...

@ koenbro - solid advice above. Continue to systematically work through the process towards excellence. One step at a time. Strongly encourage you to sign up for formal live training. Face and voice with an experienced human is best. As an alternative or complementary approach, another solid course ...

@Ant428 - material error, on my part. Wrongly assumed you were talking about welding 1/2” thick ALUMINUM vice carbon steel. In context for steel, my amperage numbers are way hot/hot. Sorry for the confusion.

@Ant428 - up your Tungsten to 1/8” for starters. 135A for 1/2” Ally, irrespective of welding position amd joint preparation, is cold/cold. You’ll need a baseline amperage of 280+A to fuse this joint, IMPO. Use 1/8” 4043/5356/4943 filler. A 280A rig with H25 (75Ar/25He) may have the boost to inject a...

....can it be brazed with decent strength? aluminum bronze? silicon bronze?.... No. Successfully joining Al to Mg, vis a vis an electrically augmented flame (ie. fusion welding) or oxy-fuel (ie. brazing), has been studied ad nauseam within the automotive/aerospace industry since the 1970s. We've le...

....Recap: Are we saying a tungsten grind that matches a sharpened fine point pencil is bad for Al and instead I need a flattened end?... For the majority of cases, you'll optimize the Tungsten's arc stability and cathodic penetration effects by properly preparing and profiling the included angle t...

Our Force Majeur for ferrous/non-ferrous materials is a 3.2mm (1/8in) Tungsten. RED for ferrous, BLUE for non-ferrous, and CREAM for special apps. 90% of the Tungsten manufactured by DGP (German). On occasion, we'll use 2.4mm (3/32in) in RED and BLUE. Ejected the use of 1.6mm (1/16in) long ago. Our ...

Is there anything out there that is new, other than bulky canvas or heavy leather? ....Any suggestions? We use a combination of materials.

....I have seen the 1 video Jody did where after welding he heated the part back up to I believe 400 degress to relieve the stress. Would you recommend that as well or is that just for thicker aluminmum?.... No need to PWHT. Unless specified by code/specs. This ain’t CERN. You aren’t splitting atom...

So does making a fillet weld larger then the base metal affect the properties of the weld like excessive face reinforcement does? No {strength} credit is given to any weld size LARGER than the required minimum specified by code. Ever. Welds exceeding the minumum size are sometimes called out and ex...

@ Aaronmnwelder - recommend you build 2ea of these assemblies “back to back”. Think symmetry. Mechanically affix the base plates to one another via fasteners in the bolt holes. Use additional clamps to achieve a flat/flat geometry. Now, you will be welding an 1/8” tube to a sandwiched base plate of ...

@ Jetman - 90% of our grinders are corded Metabos in 4-1/2" and 6". Strong as steel and smooth as ice. Recommend the 13.5A, paddle switched, quick-change WEP 15-150 . The paddled operation is ideal for safe, shorter duration work, a la with .045" Slicer wheels. If you are planning to ...

@ loudandgreen - you may have seen this article from Medtronic highlighting the cap of 160A for welding. Recommend consulting your doctor and contacting your manufacturer of pacemaker. Literature states "Frequencies between 10 kHz and 1 GHz are generally the most problematic....EMI signals in t...

We're going the other way. Sourcing 4% Thoriated Tungsten. DGP, direct from Germany. The increased volume of Th oxides will lower the Work Function (eV) and promote super smooth arc starting capabilities. Our goal is to boost the performance of properly profiled 1/8" RED Tungsten for thin/thin ...

Recommended reading LLNL’s report on Joining Beryllium . Report cites Ar/He shielding for select fusion processes. EBW is most common fusion process. Also, reach out the Fronius (German). for tech consult. They, IMPO, have the edge on state of the art waveforms and weld pool control for MIG/MAG. And...
