Hey guys,
New to the forums so if this post is not meant to be here ill move it to where it is specified.
I am very much an amateur when it comes to tig welding and have been practicing lately, but ive gotten to a point where i need to make someone else take a look at my work and situation so i can get an answer as to whats going on. I have dug many hours into research and cant seem to find answers.
I first started out on mild steel throwing down some beads pretty decently for my first time, I dont have pictures as i dont have the metal anymore however there were a couple of things wrong that i can talk about.
1) There was porosity in my welds. Tried turning the gas up and down, no bueno. I currently run 7-8lpm when welding with pure argon. Have gone up to about 11 and down to 6 each way and same result. This is with 2.4mm thoriated tungsten and 2.4mm filler rod. This is with mild steel and stainless which i have included pictures of.
2) My tungsten blacks out immediately after my first weld run, Just the tip. I run a pre flow of 1 second and post flow of about 4 seconds and every time the tungsten still ends up blacking out. I generally use 2.4mm thoriated tungsten with a size 7 cup and when 1/4in mild steel i use the pedal with max amps set to about 100. This is the same with stainless.
3) My stainless welds glow red hot after turning the touch off after trying to attempt a run which i dont see in anyone elses welds, they have a black dull colour and just look horrible. I do hold the torch close to the weld after letting the throttle go to let the post flow of argon do its thing.
Cant upload any pictures but they are as i described, the file sizes are apparently too big
Any help would seriously be appreciated, i need to get out of this rut.
