WELDING TECHNIQUES

this is stainless sheet .120 being welded over engine cradles for MTA public trans buses b/c the cradles are cracking. (its a camera phone picture)



here is a verticle



The spread out dime stack looks cool, but i've been taught you want to stack the dimes as close together as possible, b/c any dip in the puddle, is a weak spot. I just passed my D1.6 test today.

Practice Practice Practice, get comfortable, and REALLY pay ATTENTION to what the puddle is doing.

You generally use the push method keeping the gun 15-30 degrees towards the direction you weld. It helps to heat up the area you are about to weld as well. The pull method adds a lot more filler to the weld. Makes it over-bulgy in most cases. Maybe can be used for chamfered joints.

When Laying vertical beads move faster going from top to bottom and point your gun up 15-30 degrees(pull the gun).

You can get the dime effect also by welding a pool then pull back into about half of that pool you just made then go twice that distance to start another pool. For example weld 3/8" then come back 3/16" then weld another 3/8" then come back 3/16". or 1/2" then back 1/4" then another 1/2" etc. etc.

And I'm still rooting for sticky-ness!

I weld all day on boat trailers at work and this is the method everybody in the shop uses i will try and get pics up of some of my welds tomorrow we are using big ass miller welders and generally welding on 11gauge steel

I use to weld trailers for a company called Pequea. We had Miller 306 machines, ran them at 22-25amps burning from 1/4 to 16ga sheet on the same settings.

As for a tip on tubing. Start at the top and work down 1 side around to the middle on the bottom, do the same for the other side trying to start where the other sides puddle was so you dont get a low or dip inbetween, its a weak spot. Will it break on something like this? prob not, but always shoot for perfection.

we are using the CP302 on 480 power

looked through some old pics.. that is the same thing we used, not a 306.

now i use miller 300's and acouple 20 yr old 351's.

i love welding with 480 power!

how bout info anout ARC welding or is it pretty much the same idea as far as the pattern goes?

Some beads on the ranger I did...

Some 'stitch' welding. (I weld airtanks like this so I dont blow through)



A little bit of both styles in the same shot

Only advice I can say is practice. I am bad for not knowing the technical shit. I just set it where it feels and sounds right, move at a pace that seems to work and hope for the best. haha.

kinda but not realy you pull a stick and push a mig it is alot slower and not as clean you have to do alot of chipping slag on an arc welder

its kind of funny to read some of the advice on here from people who dont weld on a professional level, i thought i was a good welder until i got a job as a fabricator, and found out i didnt know shit....

cris, enlighten us

i dont know shit!
