Hi guys,
I feel like I'm beginning again, with a welder that doesn't mess me about, and with a new bottle of Coogar 5 gas which certainly beats the hell out of the pub CO2 bottle I was using before. I was wondering if you could cast your eyes over the following butt-welds and maybe offer some advice on getting better penetration. It's 2mm mild steel plate, with a gap which you can see in the photos, and with settings that you'll see in this photo here:
This is an overall view of some welds I did with different techniques, with the penetration from welds on the other sides visible as well. It looks like the two small welds at the bottom left penetrated quite well. They were both using circling push technique
Here is the reverse view. In this picture, the penetration visible on the top left, is from the weld at the top right of the previous photo, so the welds at the bottom right are for the good penetration visible in the previous photo at the bottom left.
This is a close-up of my favourite.. I did a circling push technique on it
and the closeup of the reverse side!
Any tips of getting really good penetration would be welcome
