Which Tungsten and filler rod?

[junes]

Aluminum start with some 5365 for unknown alloys and it it is being powdercoated 4043 for most things that are not being powdercoated. For steel get some er70-s6 for starters that's the all around steel for chromemolly which I dint recomend unless your a trained proffesional is er80s2 for aplications that will be stress reliever and 70s2 for non stress relieved aplications. Stainless you have to match rod alloy to base alloy alot more. If you have anything more specific you need to know just ask.

What is so difficult about chromoly?

[junes]

It's difficult because for alot of cases you have to post treat it to relieve the stress. Also irfan get brittle if too much heat is used and then you hear ting ting and welds break like glass. It takes alot of practice to do it right and make sure you use the right rod for the application and move slow when welding.

I have read that it helps to preheat the tubing first, which helps in preventing the cracking. When I get closer to welding the chromoly tubing I will make a new thread about it.

[junes]

Pre heating helps a little it's more of a post heat tempering process that has to be done right just practice a bunch and read read read. You will be fine
