Stopping an oxyacetylene weld from popping? Answered
I'm pretty sure that anyone who has oxyacytelene welded has had a weld "pop" when they jab the rod into it or overheat the molten metal. I've been doing some oxyacetylene welding and I'm working on my lap joints. When I was simply laying a straight line on weld across a plate I never made the weld "pop." Now every time I pick up a torch and try a lap joint it goes "POP!" and flings molten metal everywhere. What am I doing wrong? Can anyone shed some light on my problem? Any help is much appreciated!
