Kon said:any more pics? i can host if ya need...

2mbb said:Thanks. I think the tubes add a nice touch. The forward angle on the center tube was planned. I had to angle the side tubes forward by necessity--to clear the headlight washers. I thought I had the bumper angles all figured out, but I missed by a little bit. In the end, I think it looks better with the sides forward.
Thanks for your part in all this...
HawkDriver said:Zactly what I did with my 40 design because of the same reason, wimpy welder. I suppose that once I get the 251 amp I could add 1" pieces, like CCOT sells, anywhere on the bumper without any worry of the weld failing.
sixty said:2mbb,
One hell of a job on the bumper though, that thing looks very nice & I like how you seperated the winch mount from the bumper. how much time & $ do you think you have into it. what did you use for all of those long cuts in the steel plate?
NICE WORK!
helocat said:Outstanding! Wow that tube was a full stick not long ago, you move fast! Great looking bumper, I like how you tipped the tubing forward a bit, looks great. Well done!
110v welders: An 110v welder can do great stuff in the hands of someone who knows how to use it. I think 110v units get a bad rap since usually they are in the possession of someone who is learning. (My first welder was one) Good 110v welds are prep, chamfering out the area to be welded, flux core w/ double shielding gas are all things that lead to strong welds with low voltage. The shop next door to me is an independent SCCA race car guy. He built his entire tube framed car with an 110v welder……9 yrs ago. 7 hard seasons on it not one weld failure! (Crashes and all)
Again great looking bumper!

I don't really agree with this Corey,sixty said:It is not a problem welding 1" steel to 1/4" base metal as long as your welder is capable of welding 1/4" steel. Even if you add a 1" bead to connect 1" steel to 1/4" steel you are still no stronger (maybe marginally because the circumfrence of the shear plane is larger). also remember the weld bead is stronger steel than the mild base steel. All of this aside I think the thru the bumper directly to frame is a stronger design, just much more work.

For a good weld penetration is necessary, and if you cannot penetrate the Thick stuff the weld will never be strong enough.
No penetration makes for lots of trail fixes![]()
sixty said:It all depends on the size of bead your welder is capable of running. When calculating weld/ joint strength its all based on the strength of the steel times the area of the section of the weld bead.
the only issue with welding on thick steel is that the thicker steel will draw off more heat, but this is usually negligible providing the temperature of the base metal is not very cold.
Also remember that with a fillet weld, unless you bevel that the penetration needed into the actual joint is theorectically nothing, since the weld is taking all the force & the weld is attached to the face of the 2 base metals.
Mace said:Well, consider this.
when Alper welded the frame side link mounts to my rig he used a Miller Matic 185 (which has been rebadged as a 210 now) . The bead was about 1/2" thick and the material that he was welding to was 1/4 and 3/8" thick.
The weld looked Beautiful.. And failed miserably due to lack of penetration into the 1/4" material.
With the thermal properties of steel I would think that the physical removal of heat from a weld would be a principal issue. Hence the larger machines for thicker metal.
As for penetration being basically nothing.. Mine was nothing and it showed.
I just am having a hard time wrapping my mind around this.
Which is funny cause I am a BIG proponent of 110V welders.. But not with really thick stuff.![]()
Or letting the guy whom you stole his fiancee away from weld on your rigsixty said:so the weld pulled away from the 1/4" not the 3/8"? sounds like bad technique to me![]()
