Restarts

admin

Do u guys got and tips for restarts on root passes with stick! Is there anyway to make sure I get full penetration on each restart?For me it seems to be hit or miss..sometimes I do and sometimes I don't get full pen on the restarts
Reply:If you are having trouble use your grinder to clean and "feather" the terminated weld and when you re-strike start a 1/2" or so above the gap to give the electrode time to heat up and depending on the size of the gap use quite a bit of force to push that rod and tie in the root pass.  Unless your fit is jammed up tight this should resolve your issue then you may also need to turn your heat up. But don't try to restart where you terminated always start above it (downhand) or below it (uphand).

Reply:Gamble...I don't think you read the question properly
Reply:You are correct I did read that wrong. Have you tried to start then move back over the last bead and then move forward again?Torchmate 2x2 CNC with Flashcut CNC controlsHypertherm Powermax45 Esab ET220i Razorweld 195 MigRazorweld 200ac/dc TigTormach 770, Tormach xstechRazorweld, Vipercut/Vipermig, SSC Foot Pedal Dealer
Reply:What are you welding?If your welding pipe and putting in your root pass with 6010/7010, with your grinder, tough the edge of where you left off to expose clean metal then you can arc up ahead of where you left off, long arc the rod back to where you left off and tie in. This pre heats the area of the joint where you will re start welding and helps with penetration.If your welding plate with 7018, arc up at the back of the crater where you left off and commence welding. This ensures you have a nice fluid puddle started as you tie in to the end of the previous weld with the new weld.Good fusion and full penetration is the key with both techniques.Last edited by snoeproe; 07-15-2013 at 01:15 PM.JasonLincoln Idealarc 250 stick/tigThermal Dynamics Cutmaster 52Miller Bobcat 250Torchmate CNC tableThermal Arc Hefty 2Ironworkers Local 720
Reply:I'm welding plate...6013 root..
Reply:Use the same technique as I described with 7018. 6013 doesn't penetrate quite as well as 7018 though, it would not be my preferred rod for welding plate steel.JasonLincoln Idealarc 250 stick/tigThermal Dynamics Cutmaster 52Miller Bobcat 250Torchmate CNC tableThermal Arc Hefty 2Ironworkers Local 720
