jad Posted October 15, 2013 Share Posted October 15, 2013 Hi Everyone My dad and I are currently trying to convert some coil axles to leaf springs. We think the welder he have is not up to the job of welding 6mm steel and we are not getting enough penetration. My dad has welded a joint from both sides and cut it in half to look at the results. is there someone on here that can have a look and give a more expert opinion as while we are happy with the competency of our welding we are not sure whether or not we have enough power! Cheers Jad Quote Link to comment Share on other sites More sharing options...
De Ranged Posted October 15, 2013 Share Posted October 15, 2013 Looking at that, my first opinion is the welder is up to the job... but you will need to "v" out the work where you intend to weld You need to do a different style of test... "v" out the edge of two pieces butt them up and weld them.... when it is cool clamp one side and using a large adjustable spanner try and snap it on the weld... take a pic if you manage to brake it Quote Link to comment Share on other sites More sharing options...
moose Posted October 15, 2013 Share Posted October 15, 2013 Not a expert, but my thoughts.... turn down the wire speed a bit especially on the rear of the piece where you doing a butt weld. did you push or drag? it looks like you dragged... if your pushing then you can use a lower wire speed and so go slower and get more heat into the piece. also remember that your test piece is small so you will get heat into it quite quickly. I would say your welder is up to the job, whats the amps ? Paul Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted October 15, 2013 Share Posted October 15, 2013 What he said. You need a better camera too For 6mm you want a decent "prep" along the edge so the weld can penetrate a bit better, turn the wire speed down & go slow, all the standard procedures...
