Reply:still trying to develope an eye for determining whats been used on a weld. welds on the top of the angle iron looks beautiful by the way

Reply:what technique do you think was used?
Reply:Straight stringer run across the top and then vertical down. Probably little if any motion used from what I can see. Not the best way to get good penetration on a bead, but many like it because you can support the puddle with the wire and it's easy. Vertical up would have given better penetration.You can tell by the way the ripples in the metal are shaped. The rings always point towards where the bead was started. Also the end is shallow and the begining is more humped. He ran the left bead 1st and then the right, because the right sits partially on the left.Last edited by DSW; 07-13-2011 at 11:36 PM..No government ever voluntarily reduces itself in size.

Reply:vertical down is acceptable for thin metals(up to6mm or 1/4") any thing thicker and you will get lack of fusion problems, i regularly weld v down on thinner sections

Reply:i used my mm251 Attached Images
Reply:The overhead fillets look to be a little on the ropey side. A little side to side oscillation may have helped flatten them out. However, since the beads look like they're a little on the cold side increasing the voltage and wire speed might have been what was needed. Taking the time to remove the mill scale from the weld zone would help weld puddle wetout too.I use to own a MM 251, and the unit has a fairly high inductance level. If you have the unit dialed in properly ropey welds shouldn't be an issue with most brands of ER70S-6 wire.The angle up rights look like they were welded to the sides of the bed frame did you V-up or V-down on these?Last edited by Dan; 09-02-2011 at 04:36 AM.ESAB Migmaster 250 Hobart Ironman 230Multimatic 215TWECO Fabricator 181i & 211iHH125EZ - nice little fluxcore only unitMaxstar 150 STH - very nice
Reply:Why not have the side panels removable and the back panel folding downwards instead of crossways (again, removeable but hinged off the bed of the truck), making the truck more versitle and easier to load with (or without) a fork lift?
Reply:Hey Ed. Nice build!If you don't mind my asking, what is the customer using the truck for (apart from hauling stuff! )?
