Does this weld look ok. It looks to me better than previous ones i have done but before i get to excited and think im might be getting used to this i wanted you guys to have a look.
There's porosity showing at the end and i reckon you have it all through the weld to a degree. I think it's a gas issue rather than cleanliness. Check that you are getting the right amount of gas coming out of the torch.
With the gas issue corrected your welds should start to look better
Hahaha thats why i like to ask on here. Brutal honesty you cant beat it
You maybe right on the gas issue. Im only using disposable bottles at the minute
Goin to get a bigger bottle on the BOC deal as soon as christmas is out of the way.
PDG i did not weave more just took my time although there may have been a slight weave while i was working on my speed. Also yes i know the steel should have been cleaner.
But besides the lack of clean steel and bad gas situation, is there any info you can give to my techinque which will also help me in the long term??
Good chance your bottle is empty then, or the reg is goosed. Common problems with disposables. You will notice night and day difference with proper gas.
Don't weave. Keep the wire dead centre on the joint and move forward with a steady hand and a constant speed. The rest is practice.
Keep sticking your photos up, plenty of people happy to help you along the way.
I'd put money on the disposable bottle causing the issue here as you really do struggle to get the desired flow rate and they run out after a few mins. it doesn't look particularly thick plate so a bottle of 5-15% co2 would suit you nicely. Perhaps looks a little on the cold side too. Don't be frightened to crank everything up and blast it down straight and steady.
Here is a mig with 95% argon mix set up by my self to cater my technique and metal its only 6mm mild steel no perosity in sight. This is what I'd say you should be looking to achieve on every weld I may be wrong but your welds not the worst my apprentice tried his hand at the mig the other day here's one of his attempts
