How much training you need to pass this test depends heavily on your skill level and familiarity with the code book (AWS D Structural Welding Code – Steel). The test should take no more than 3 hours. The details of the test plate are as follows. 3G MIG Welding Certification Test Cap Weld. When doing the cap you have to wait for the test plate to cool down to the point where you can touch it without burning yourself. The cap pass is going to produce a lot of heat because you will be using a wide weld. Here is the cap weld before cleaning off the filler wire cleaner. Heat input (joules per inch) = Volts x Amps x 60 divided by travel speed (measured by in/min) I suppose there is an "assumption" that a weave (particularly a wide weave) will not have the same "forward" travel speed along the joint, therefore given all other info remaining the same, the heat input increases due to the slower travel speed. A 4g Mig Welding plate test along with a 3g are used to qualify a welder for all positions. If you watch the video you probably wont even need to read further but just in case, Here are some tips for passing an overhead mig welding test. Video shows Tips for passing a 3g Stick Welding Test 3g Stick Welding Test and tips for vertical One very common stick welding test is a 3g along with a 4g plate test using 3/8" (mm) thick plates, 1/4" (mm) backing strip, 1/4"(mm) gap, and electrodes. Check your gap on both ends, tighter side goes to the bottom of the weld, and weld upwards to the looser gap as it will close up during welding. Using 1/8" @ 80 - 85 amps, strike your arc on the bottom tack and long arc slightly to let it heat up. As you progress upwards over the feathered part of the tack, shorten your arc, and start. Tacking them at 90 degree angle and welding the joint from the outside corner, gives me very good practice for a 3g butt weld with bevels. In fact, its so similar, that I used the exact same settings as I used on the beveled plates. and here are the settings for this 3g mig plate test. root pass –19 volts and ipm. fill pass—19 volts Hey Guys, I have a weld test for a job coming up soon and in order to be successful i need to complete the welds so they pass x-ray. Now the only problem i have is that i haven't had much experiance with postional welding with fluxcore, so what i am after is just some general tips and tricks i should know to help me through. but im pretty sure the inspector will want us to weave up, with set to about on a miller syncrowave , so i dont think welding up 2" then 4" will actually work in the way your talking, but i did have to do that when i did my flat test I think i may weave up 2", stop, weave up 4" stop, then continue, cant hurt i suppose. this Mig welding test is used mostly as a preparation for pipe welding. The settings that you get dialed in for plate will also translate just fine over to pipe welding. Downhill root and uphill. Set the wire feed speed. Wire speed controls amperage as well as the amount of weld penetration. A speed that's too high can lead to burn-through. If a manual or weld specification sheet is not available, use the multipliers in the following chart to find a good starting point for wire feed speed. sdgcoolstore.com taking a welding test is hard enough. here are some tips for a structural welding test aka plate. Flux core welding test advice It's 3g no backing strap. It's a mig root and fill cap with fluxcore. Setting your heat and wire speed will be key. You don't. Heat Input Problems It is important to know your heat input into a plate when you are welding, as well as heat limitations for different metals. Some metals are more heat-insensitive than others, and damage caused by too much heat input might not be detectable for days. The heat input (H) equation is. To become qualified to weld in flat, horizontal and vertical positions, you should try to pass the American Welding Society (AWS) D 3G GMAW welding certification test. The people behind sdgcoolstore.com have put together a great guide that details what it takes to pass the 3G MIG welding certification test.
