would u trust this?

[rockin562]

well i have been trying really hard to work on my welding and i really want to weld my step notch in soon and box my frame. so i have been welding metal that is thicker then the 3/16 thick frame. i have tried everything i can think of to break it and no luck. this was also done with a lincoln 110 welder. please any input.

The only way to tell the intergrity of the weld is to cut through the weld area and get a cross sectional view. It looks good on the outside though.

You dont want to see any pitting or porosity. The welded area should be uniform in both pieces of metal.

The excessive splatter means something. Dirty metal surface or incorrect gas pressure or wire speed. I'm not a welder by trade, so maybe one will chime in.

Miller Welding has some great how to videos online.

You do not want any spit or splatter going on. did you clean that spot well ? wire brush,grinder (if have too) sander? make sure its clean number 1# key to welding. 2# key is to make sure your wire speed is right and gas covrige (i cant spell) is there. ive never used a llincoln mig welder only tig welder. but i know on a miller 180 there is a chart on what wire speed and amps to run. 4.5-5.5 and wire speed of 55 on a miller you can weld anything besides sheet metal or anything crazy like inch think metal.

From the photo it looks ok besides the spit and spatter, check the chart i think yours has one, if it comes out like that again after u have cleaned it good mess with it move amps up and down wire speed find what works best for u. that will help u a lot with welding, u will find what works best and also see what low amps and fast wire speed will do and the other way around lol. keep at it and u will get it down. also try somet joints that will help a lot too.

If anything it looks like you may have moved to fast build up a little more weld go a little slower and make it even. Once you get rid of the spit and spatter it should hold watch the ends of your welds when you do the notch. Those are we're the cracks begin of they do

always thought you should only use a 220 welder for frame work

Not necessarily, a 110v can do the job. IMO most is on the skill of the operator.
I've seen some welds, that even with a 220v, I wouldn't trust.

[rockin562]

Thanks everyone. I really appreciate all the input. I have a few hours a day to practice for a few Weeks.

Are you running flux core? Looks like it to me, which would explain all the splatter

[broey]

thats what I was thinking. looks like flux, if not you can turn the pressure up on the regulator a little bit. somewhere around 20-22psi works the best for me.

[rockin562]

actually right now i am using flux core because im out of gas and also i heard it is a hotter weld without the gas. is that correct?

[rockin562]

also would it be a good idea to weld my notch in then go over the welds with a grinder just alittle to clean them up and then do a second pass with the welder? this is the first time of me doing a notch and bag brackets so i dont want to screw it up but i do want to do it all myself.

[dv8customs]

I wouldn't worry about multiple passes. Just try to do a better job of evening out the bead. You have too much on the left hand piece in the pics. You could benefit from preheating the steel a bit too.

[walkerscott]

if you wired brushed the weld .. how wide was the original HAZ heat area
i am not an expert but stay at a holiday inn once ...


actually my nieghbor is an older gentlemen who is very respected in colorado as a welder in the day he was the only fellow in colorado to be cert on 80series rod thru bethal steel
today he is retired

he tells me heat heat heat

[andrewmp6]

practice makes prefect remember that.
