alloy filler rod tig / advise ,

[powernut]

sorry to sound a bit thick daft , as i assumed alloy is alloy , reason i ask is that im after some alloy tig filler rods ,and due to not knowing which i need , can anyone advise which ones i possibly need, because a ebay seller sent this message , but im a bit unsure which buggars i need,,

ALUMINIUM ALLOY then you must have an AC TIG Welder. I can send a mixed pack of 4043 & 5356 1.6mm & 2.4 mm.
If you mean STEEL ALLOYS for use with a DC TIG Welder I can send a mixed pack of types A15 & A18 for mild and low alloy steel.A18 is for mild steel fabrication and A15 is for mild steel & low alloy steel including pipe welding - it's also used for repairs to steel that has corrosion in it.
If you want a pack of each buy two packs and I will send enough to get you going.
Some people use special lightweight strong steel alloy tubing called 4130 Cromo for bike frames and roll cages. If you are using this then you will need Sifsteel No 32 aswell.

ps i have my china ac/dc tig ,which ive had a few goes with it , which i think i may post a few pictures up , once my tig welds inprove

The cause of the confusion here is that you are referring to aluminium as Alloy. An alloy is a mixture of metals and is not an abbreviation of aluminium.

If you mean Aluminium then it's better to say Aluminium, or Ali for short.

Alloy as in Aluminium you will need both 4043 and 5356, one has 5% mag the other 5% Si. If you are welding steel then go for the A**

4043 contains 5% Silicon and 5356 contains 5% Magnesium. Having both will cover most jobs. Get both 1.6mm and 2.4mm in each grade.

I m just about to start and have a go at making a mess of some ali and have got to order some rods
what jobs would 4043 be good at that 5356 wouldnt and vice versa
My first attempts will be to make some cut down motorcycle sumps so i presume crap aluminium alloy is the main issue here please advise

Aluminium filler selection chart

Cliff notes version...

Cast alloys 4043
1050, 3103 (soft, very formable sheet) 1050 filler ideally
Extrusions and 6xxx series plate 4043 or 5356 both work. Pros and cons to each, 4043 typically more 'forgiving' to use. More detail in the knowledge section of Alcotecs site and a search of the forum will get plenty too
5xxx series alloys (treadplate and sheet typically) 5356

Modern motorcycle castings are usually quite good quality but a sump will obviously have spent it's entire life soaked in oil...
