sbchevfreak Just a quick explanation of what I posted earlier about vertical welds on factory frames:

From "Welding Essentials" by William Galvery and Frank Marlowe. . .


"Do not place any welds perpendicular to the channel. Welds perpendicular to the channel concentrate stresses on just one section of the weld. This is because end welds on the patch plate prevent beam stress from being distributed evenly along the weld length. They become a new stress riser and will produce near term failure."

This is also what is taught when I took my AST apprenticeship.

John long I have never owned a pair of welpers. I have always just used side cutters. The welpers looks like a neat tool. Is there a particularly good brand or are they all similar?

Brian , Ebook time ?

Brian has written excellent articles on welding, Auto body repair, that newby's probably haven't seen, I printed them off a few years ago and filed them in my welding notebook , told junior to read and improve his welding,
Brian can you have links when you post. also there is a lot of great informatioon others have done, I am thinking Dan's interor-upholstery posts.

It's probably safe enough for grass and tree saplings, but I'd hate to hit a concrete curb or big rock with them. I have welded new cutting edges on shredder blades, but made the welds in line with the blades, not butt welds. I just hate to see anyone get hurt.
not sure if this question was ever answered. I'd say sleeve it with an insert after measering up/down/left/ right to insure it's in the right place. Nowadays I-car recommends to cut 1/4" slits on each corner of the frame end and taking duck bill pliers to bevel each end so it slips perfectly into the new frame horn, then welding it shut. They most likely only recommend this over a sleeve approach due to newer cars being unibody cars designed to colapse in certain ways to avoid whip lash. If it's an older car there's no need cause it's not designed to lure impact forces in certain directions or dissipating energy. If you get rear ended in an old school break your neck with pride.

That might work for you but I sure wouldnt give that advice to anyone else.

zbhover I don't know about anyone else, but if I don't have my welding jacket buttoned all the way up and I weld for a while I end up with a nice "sun" burn in a "V" shape between my mask and jacket..... I can't imagine not wearing a mask....... I'd be crispy for sure..........

Then again If I'm Mig welding at work I usually am welding at 26-30volts with the wire speed cranked up, maybe welding sheet metal would be better, but I'd say always wear a mask, the risk of burning your eyes or getting a nasty "sun" burn aren't worth it.......

I know you should cut the tip of the wire off, every time you make a spot weld

that is a very time consuming and awkward process (I feel like I need 3 hands)

today I just stopped putting the welpers down, and now use them to hold the end of the mig torch, when making the spot weld



it makes me feel like a welding robot
I couldn't pull that off but looks like a great way for you. I just know I couldn't hold it steady or something.

If you posted it then it's your opinion too. Everyone has one.

Shredders are driven at a relatively high RPM and could send a broken end a long distance and cause injury or death.

"Have you ever seen someone throw an axe or a knife into a big block of wood?* *Imagine that was a bystander."

gow589 The combo cleared woods which was mulching down small trees. I can not imagine a more aggressive environment.

It's not the what but how.

the forces against and the way stress is applied to a truck frame is different than those blades
