[QUOTE="adamb4321, post: 156481, member: 838"] Hi toto, I agree it pulls towards the side of the weld, normally. This beam didn't do that, counter welding to pull it back into position made no difference, it just pulled away which ever side I hit it on. What I did notice that after welding and resectioning the gaps were quite big even though the disc was only 0.25mm, it's like the metal contracted by a large amount when welding. If the gaps large I weld over the face of the cut to reduce it before welding together. It's damn annoying. Ultimately I'll have to remake it I think. [/QUOTE]
