1 00:00:10,449 --> 00:00:12,569 Hi, everyone. Welcome to another welding 2 00:00:12,670 --> 00:00:15,059 and demonstration video this time an MMM 3 00:00:15,159 --> 00:00:17,039 T Fillet, hopefully you've already 4 00:00:17,139 --> 00:00:19,719 watched our MMA introduction video. 5 00:00:20,020 --> 00:00:21,359 If you haven't, I recommend you watch 6 00:00:21,459 --> 00:00:23,340 that first to pick up some tips on how 7 00:00:23,440 --> 00:00:26,309 to set your machinery up and then watch 8 00:00:26,409 --> 00:00:27,629 this one afterwards for a demonstration 9 00:00:27,729 --> 00:00:29,459 on the T Fillet. The material I'm using 10 00:00:29,559 --> 00:00:32,280 today is five millimeter thick, 11 00:00:32,380 --> 00:00:35,580 low carbon steel. This time it is 40 12 00:00:35,680 --> 00:00:38,460 millimeters wide by 200 millimeters 13 00:00:38,560 --> 00:00:41,020 long. For this demonstration I'm using 14 00:00:41,560 --> 00:00:44,970 around 110 amps and the rods I'm using 15 00:00:45,069 --> 00:00:48,540 are sixty 13 rods. What I'm going to do 16 00:00:48,639 --> 00:00:50,520 first is tack up my two pieces 17 00:00:50,619 --> 00:00:53,980 of material. So, with any T Fillet, 18 00:00:54,080 --> 00:00:56,490 in the middle at 90 degrees, you can use 19 00:00:56,590 --> 00:00:58,680 a magnet to aid with this. The more 20 00:00:58,779 --> 00:01:00,450 experienced you get, you might just want 21 00:01:00,549 --> 00:01:01,620 to hold it on top which is what I'm 22 00:01:01,720 --> 00:01:21,480 going to do today. Once I'm happy that 23 00:01:21,580 --> 00:01:22,739 the material has been tacked up, 24 00:01:22,839 --> 00:01:24,849 I've just put a small tack on either end 25 00:01:25,059 --> 00:01:27,059 on the back side of the weldd again 26 00:01:27,190 --> 00:01:28,830 so that the slag doesn't interfere with 27 00:01:28,930 --> 00:01:30,930 the weld I'm you're going to complete. 28 00:01:31,449 --> 00:03:01,059 We can start with the actual weld itself. 29 00:03:01,160 --> 00:03:04,689 What we should have is the slag peeling 30 00:03:04,789 --> 00:03:06,519 off on its own, which we do have 31 00:03:06,619 --> 00:03:08,889 at the minute, so with MMA you have 32 00:03:08,990 --> 00:03:09,970 a little bit of cleaning up to do once 33 00:03:10,070 --> 00:03:11,589 you've finished your weld. So we'll use 34 00:03:11,690 --> 00:03:14,909 chipping hammer and a wire brush. 35 00:03:15,009 --> 00:03:17,169 So nice and gently with the chipping 36 00:03:17,270 --> 00:03:21,389 hammer, not to damage the weld. See 37 00:03:21,490 --> 00:03:25,009 the slag came off nice and easy, 38 00:03:25,110 --> 00:03:31,899 a little bit of a wire brush. That gives 39 00:03:32,000 --> 00:03:34,839 us our finished article, once you've 40 00:03:34,940 --> 00:03:36,889 cleaned it up, we can inspect the weld. 41 00:03:36,990 --> 00:03:39,879 Nice, even leg lengths, a fairly 42 00:03:39,979 --> 00:03:42,949 consistent weld. Overall, fairly happy 43 00:03:42,949 --> 00:03:43,470 with that result.
