When I bought my new Lincoln 216 welder, I also bought an 11 pound roll of ER-70S-6 wire. I bought a metal gauge and estimated that the project at hand was about 1/4" metal thickness. The chart on the machine called for a "D" setting which is about 4 out of 6 possible settings. (Can't remember the wire feed speed off the top of my head. Seemed to work out okay.) Didn't get much splatter. If there are concerns over the integrity of a weld, how could one strengthen the weld? Would you choose to build up a higher crown with a hotter setting, broaden the base of the weld, etc.? Davi -
One of the popular HD videos at the magazine website and the magazine's YouTube offerings is a field repair welding job at Moab, Utah during the 2012 Jeep Safari. We were at the "Rose Garden" trail on a typically fun Warn Industries media run. I happened to be riding passenger side in a Jeep TJ Wrangler whose owner was the trail boss and a fellow Warn friend. My role was filming, and the lead vehicle was a good place to ride. About 2/3rds of the way up this rock ledged step trail, I was outside the vehicle filming when the steering tie-rod on the TJ Wrangler snapped. The next angle for the -
If you need an overview of welding processes and tips on how to weld, there is already a good block of welding information and instructional material at the magazine website (www.4WDmechanix.com). I just dropped the word "welding" into the magazine's search box and the URLs below came up. Many weldors like the gas welding insights, gas welding is a great foundation for TIG and very useful for light gauge and smaller metal parts where a diffuse heat is advantageous. When time permits, I'd like to do an instructional/tutorial on each type of welding, and make the series available for Vime

When i bought my 1994 Dakota, i noticed that the fan shroud was missing. They had rigged an overflow bottle on the core support. When i tried to put a new fan shroud on it hit the fan, so after some searching, i found that the frame was bent right behind where the core support mounts to the frame, which in turn pushed the radiator and core support back a bit. The reason i didn't notice it at first was because they had also made sure to realign the headlights, as well as replace the grill, so all i noticed was that the bumper was bent in. The bend is in front of where the front suspension

I posted a topic at the welding and metal fabrication forum on one way to restore a bore in a stamped steel piece: "Weld Mold 26-C 'How-to' Oxy-Acetylene Repair: Restoring a Stretched Bore in Stamped Steel". In that 'how-to', I mention heat treated metals and also refer forum members to one of the magazine's slideshow video presentations. The slideshow discusses a major concern when welding, brazing or silver brazing (hard silver soldering) near heat treated parts. Many automotive parts, especially wear points like gear teeth, shafts, splines, thrust washers and running surfaces, have be

Metallurgy and heat treating are a vital part of metal fusing. It is not simply a good bead or welding technique that assures a safe, quality weld. Filler material must match the base metal. Heat treatment is often involved after the machining and finish of alloy metals. Chemistry is a critical part of metal selection and the choice of welding filler materials used with specific alloys. Metallurgy and heat treatment are not abstract processes for manufacturing only. I have repaired obsolete gears with chipped teeth, where the 8620 base metal has been case hardened to 0.035" or so depth at

Welding can be a gratifying vocation or a hobby. Some weld for a living, day in and day out, and I taught adult education level students to value this trade for automotive body, chassis, structural, casting, maintenance and repair work careers. In this forum, the community of professionals and hobbyists can come together and discuss the various aspects of welding and brazing: stick (SMAW), oxy-acetylene (gas), MIG (wire feed or GMAW, solid wire and fluxcore), TIG (tungsten electrode or GTAW) and silver brazing (hard, higher temperature soldering with oxy-acetylene). Fusing metal properly i
