Vibrating chassis while welding.

Just seen this on NHRA at Pomona. I believe it was Shumaker Racing. Welder on each side of chassis welding together to prevent distortion plus they vibrate the chassis to relieve stress and to relax chassis, Am I the only one who had never seen this?

My guess is Schumacher's company makes that machine and they want to send all the other teams on a wild goose chase buying some hella expensive machine and wasting time with it while shoe focus' on other things that matter lol

The process does in fact reduce residual stresses in the heat affected zone of the welds.

It was a cool thing to see. the fact that they weld both sides at the same time was also something neat and keeps the chassis repeatable.

Providing advice based on WINNING CHAMPIONSHIPS AND RACES across the country in door cars and dragsters from 12 seconds to low 6 seconds in both (not a first round by bye-back window regular at the only track I go to). Providing WINNING ADVICE BASED ON FACTS AND PERSONAL EXPERIENCE ON CARS I WORK ON, OWN AND RACE. Not unsubstantiated opinion I came up with sitting on the toilet.

I heard years ago that when WJ ordered new chassis that he specified that the same welder build both of the cars, place tubes in the same order of welding and weld all welds in the same direction. He further claimed that a left handed welder and a right handed welder created different cars, which is probably accurate. Now... how much of that actually helped anything or improved consistency? Who knows. One day I did ask Jim Yates if he could have a wish between: 1) perfect setup IE: air, clutch, gears, shocks etc or 2) 5 more HP which would you choose. He said 5HP every day.

I have a hard enough time seeing the leading edge of the puddle and keeping both hands braced and working together as it is without the damn thing shaking while I'm welding

We have to get our pressure vessels recertified whenever welding is done to them. Nothing about vibrating is required nor suggested. For whatever that is worth.

Most commonly, the vibratory device is applied after welding to relieve stress, essentially replacing PWHT. But it also can be applied during welding to improve weld quality through grain refinement and stress reduction. In fact, applying the right vibration during welding can eliminate the need for PWHT completely, unless tempering of the heat-affected zone is required.

I generally shake like a bear cub shytting a pine cone when I'm welding anyway, maybe I could sync it with the chassis vibrator and get 'er done!

SmileSo, when DSR and JFR leave the sport for good which I think is coming sooner that some think, that leaves things about 8 cars short. Will it matter then if the tubes get shaken while welded? My point is, these two teams have just about chased everyone else out by spending money because they could spend money. The same has happened in NASCAR land, the teams that can, will do. The downside is that the sport is self-destructing due to it and the powers that be just stick their heads in the sand and hold out their hands.

Don't worry there are plenty of up and coming junior dragster racers that are ready and willing to take their place and we will have 25 to 30 cars in every class.

with the money some spend for Jr. dragsters T/F isn't big leap.

Don't worry about some expensive vibrating machine. Can achieve the same process when the washing machine is overloaded for 1/1000 the cost.If they only knew lol.
