Very nice weld monger thank you what about the use of 3 main categories of
magnesiun where to use them . So far I thought the best rod for cracks
was Si12 ..

How can you tell what kind of aluminum is ? so you can use the appropriate rod.
The way it goes I will to weld it .

Thank you all for your valuable suggestions and comments , i must agree that contamination of the basic metal is the worst thing of all . I conclude that repairs like this should be done once and very well. The welder that weld it in the first place did not weld correctly so it end it up an almost h...

any advice will help , someone weld this and he came to me for cure

Dear mat ,in general welding starts from middle so it leaves room to expand ,cool and continue , force draft or spray water for faster.|You can make this spiral on a strong lathe or in pieces and strong heat to reform it

Drooping machine is a constant current machine like tig , something very useful, so it can be used but it is a risk to burn it. If it was cheaper i would have tried.{Drooping Type (Constant Current): Drooping V-I characteristics is used on constant current type welding machine. When arc is struck in...

thank you all , but i insist , i want to weld 4mm thick metal to 0.4 mm , so i'm willing to try , it is like when the tungsten stucks
...any drooping machine in dc capable to provide 250 amperes will do what is this drooping? in dictionary is bend over something not right ....

the way i figure it out is that the tungsten does not light arc and is in touch constantly .
the book of 57 the replay is : time is the moving picture of the unmovable eternity ,plato. you know that im greek i recon

correct but still something is missing try this go to my picture in forum then use save as ... jpg and then in paint you can read it

no , you put a tungsten to the ground wire of tig , with the the torch tungsten touch the sheet metal

the procedure you describe is something different , if you know resistance welding two electrodes by force in sheet metal , spot welding in tig is similar no pressure but in constant touch then press the button and it melts the two pieces together like resistance welding the timer switches of the cu...

thank you , there is a difference in spot and tack welding im not sure about it . Spot welding is like using the electrodes in touch with thin sheet metal and press the button of tig , spot timer stops current . It takes some practice. Tack is longer and manual. The question is if an expensive tig m...

this will help

hi does anyone used tig spot welding like resistance welding

Actually was the idea to buy a better machine with pulse and the rest of goodies,after plying around I ended up to using 60Hz.

I had a go today on a heavily rusty aluminum cooler it had a hole in it sorry that there is no photo. I thought that the procedure might be helpful to some so i describe it .Clean well since i did not know how many amperage it will need so i started slow 25 amperes.I made the frost zone around hole ...

All seems fine , but it will be a major problem with distortion so first tacks and most of the welding will be with the
head assembled without gasket well torqued or you will have a bad surprise ...4047 tig rod .

You might like this , I had for many years a DC tig only machine and the only way to use it was the use of aluminum electrodes of a usual stick welder . With pure argon I establish a DC tig arc with argon flow and when base metal melted I added the electrode , the paste melts and broke the surface o...

This is the gear box of a jeep , I used 3.2 lanthanated and the notes are like this , the tungsten does not ball when AC cleaning
is low and it splits at the tip.When cleaning is adequate then it balls. any ideas? The amperage was 170 A .

This is an idea of what it will be like to use a stiff red tungsten and 1.6 diameter and 160 Hz it will help when you have to do something like this or similar

it worths saying to use in small items of aluminum red tungsten 2%thoriated , 1.6mm diameter to the amperes that will possible stand like 60 t0 70 it works almost perfect ...

Dear friends does anyone has tried to use RED tungsten in AC tig welding in an Inverter machine and was pleased to see that it works well

It is 5052 its hard for this job previously i used softer usual aluminium that bent under stress Silicon that it is in 4043 end 4047 makes it better when it shrinks.Maybe there will be an application for the 5356 i don't know yet .Maybe in thick blocks like cylinder heads might be suitable.For what ...

Thank you , I tried everything possible but in vain 5356 seems not flexible when it cools.Same settings when
i used 4043 or 4047 everything is fine . The only nice bit i noticed is that in the edges it is more easy to stay seems less flowing.I wonder what will be like in thick pieces.

So hello everybody happy new year.I have tried to weld some aluminum propel and i have seen the the 5356 welding rod
makes cracks so i switched to 4043 and 4347 and seems ok, any ideas where do you use 5356 successfully ...
