Hi I do a lot of cast iron repairs turbo chargers etc. and where possible I always use the TIG with silicon Bronze filler. For the job you are describing the important thing to note is that the weld must be completely flat when finished. To arc weld this a Nickel rod would be the norm but the proble...

Hi I make aluminium boxes out 40thou 6061 sheet of course I use 1'' x 1'' angle with a 1mm wall to frame the box then its easy to weld the edges together butt weld backed by the angle. Is there any reason you could not have even a 3/8 strip behind the joint tack this on first and then you would get ...

Hi and welcome to the forum I'm a similar welder to yourself but Darrell F is who your looking for he will have the info you need. Regards Bert

HI Matt, I've been TIG welding for a long time and I would definitely recommend TIG for Alloy car bodies. I have welded BMW car bonnets as the 5 series has an aluminium body. I've also welded a broken shock mount on the chassis of a 5 series. In the case of steel car bodies I use TIG brazing with si...

HI Darrell, Sorry for the late reply I haven't been on the forum in a while been so busy. To answer your question 5356. The reason is 6061 Aluminium is a primarily a magnesium alloy about 1% and so is 5250 about 2% magnesium and 5356 is a 5% magnesium rod. So the 5356 is closer to both alloys and wo...

Hi your most welcome to the forum. Enjoy Regards Bert

Hi welcome to the forum, I've pretty much the opposite set of skills to you 30 years TIG and MIG, I do a lot of Aluminium and Stainless steel and some Titanium, Magnesium and Cast Iron. I am mostly workshop based with guys bringing me Car, truck, yacht, boat, industrial equipment and bicycle parts b...

Hi I've been TIG welding Aluminium a long time but I'm not sure exactly sure what your asking or what you are trying to do. In order to TIG weld Aluminium you must have an AC/DC welder it must be set to AC. Argon gas is used, it sounds like you have a scratch start TIG does it have an AC setting? Pu...

Hi To answer your question yes soluble oil is the best for that type of cutting. Multi function cutting oil by LubeSol. You can buy a 5 litre drum of soluble oil and then mix it your self, for steel a 5% oil to 95% water mix is good, and for Stainless steel a 9% oil to 91% water. So roughly 1 part o...

Hi wow a turntable that is a great idea! and 0.9 nozzels are on the way thanks alot that really was a big help, I'm looking forward to my next lot.
cheers Bert

Hi typically for pulse welding you have the high amps or welding amps at a higher ampage than normal welding
current 30 to 50% higher and the backround or low amps at 30% of the high current. I hope that helps.
Cheers Bert

Hi your very welcome and I look forward to any questions you might have regarding TIG welding. Best regards Bert

HI! for TIG welding aluminium you set your machine to AC . The TIG torch connection is the same connection as it would be for Steel which is DCEN (electrode negative) or the negative connection on your welder. You always use the same connection for TIG on the welder, you just change the AC/DC switch...

Hi Guys thank you very much for your replies, much appreciated. The Plasma Torch on my Stahlwerk 50 is an AG60 do you know if it is possible to buy different tips to suit thin material for this torch? I didn't know there was different tips for different thickness material. Should I try and change th...

Hi I've been TIG welding cast Aluminium parts for over 25 years so it's not at all a problem, you first need to clean the part really well, if you have a die grinder with a tungsten burr that is ideal, if not a grinder with a new disc if not a file then a stainless steel wire brush, then some Aceton...

Hi Guys I'm here in Dublin Ireland, looking for some tips on how to cut out a flange without getting so much distortion. I cut out a 9'' OD circle with a 6'' hole with my plasma cutter, out of some 1mm (40thou) mild steel and when I was done it buckled so bad that it was unusable. So I went again wi...

Hi Guys thanks very much for your replies. I was only using one of the white insulators. I found initially when I put both on I had trouble clamping the electrode. But obviously I will now use both insulators. I really appreciate the feedback, it's great to have really good information from experien...

When welding 1/4 inch (6.4mm) Aluminium with AC TIG using a gas lens and 3/32 ( 2.4mm) Tungsten the Front often breaks off my Ceramic Cup. I'm using a no. 7 Cup with a 3/32 Electrode 2% lanthenated with about 1/4 inch stick out, A nice little bit of balling at the tip and about 15cfh of Argon flow a...

Hi I use 4043 on All castings Cylinder heads and Engine parts it's the silicone in the alloy that helps the weld to flow and tends to be shiny in comparison to 5356 which has magnesium.

Hello MotoEngineering here a new member and a big fan of Jody, I've been welding over twenty years mostly TIG, I do a lot of Aluminium Welding but as I do alot of parts for motorbikes, I do Titanium and Magnesium as well. I have my own small Engineering Shop in Dublin where I have a Lathe, Milling M...
