The welds do look quite high tho come to think of them.... But it will only be used to hold my gas bottle in so they should be good U can tell where I stopped and started on this one
Couple of points when you are welding those castor wheels, they normally have a galvanised coat or zinc plating.Its best to grind it off if possible,the fumes are probably not healthy.*
Also, the castors usually have ball bearing races with grease packing, if you get too much heat in, you will drive the grease out-maybe even fire it up.**
A more practical approach is to weld a plate across the corners, drill it and bolt the castors on-that way you do not damage the castors, plus you can remove them if you change the project later or damage a castor.
If you cannot source suitable plate, use flat bar instead.
* Argon gas mixing with other materials which produce gas/fumes when heated at welding temperatures may be bad news- so always be mindful of what you are welding-get it-and the surrounding areas as clean as possible and get max ventilation possible and/or take breaks in fresh air to let work area clear.
All welding produces ozone gas, MIG tends to produce the higher levels, so again, take breaks and keep area ventilated,-but don't get in a sweat about it- at our levels of exposure its probably not a big worry-and I think some of the MIG gas mixes for MIG now reduce the production of ozone.
** Working on jobs where grease or oil is present obviously presents a fire hazard, but also, if you weld near packed grease , it can explode if its sealed in and can't go anywhere if it gets superheated.For similar reasons, never weld on wheels with the tyre inflated-obviously-its best to get the tyre off and away-but if you can't, let all the air out of the tyre and stitch weld with cooling down breaks tween welds.
There is no need to get hyper elf n safety about all that, but just have a think about what you are going to weld up and where-and if in doubt, post up wot U wanna do on here as some of the lads are pros in the welding game and know all about the safety stuff and are up to date on hazards.
totally take on board what your saying mate, and I didn't really think much before I was doing it...., definantly something to keep in the back of my mind and all the points have been taken on board....., any points on the welds at all?
The welds look ok and the fit up looks good, it looks as though they have stayed in square and not pulled, if you have to stop and restart- it looks as thought you might have done in the weld in fillet joint- try to run a ramp down when you stop so you can tie in the start of the next bead, or if it was a stop due to earth probs, take a nick out with the grinder to tie in to.
Looks like you are on your way.
Yeah I've had the problem of castor plates welded on with trucks for use onstage, they work for abit but half way through the run of the show....they jam up 'cos the grease in them or the nylon bearings have been screwd by the welding heat .....jeff
cheers fix, it was more of what I had lying round but you can see from the burn marks that there was a bit of heat there from the greese charring...something to note,
