Hi everyone, hopefully you have watched

2
00:00:11,630 --> 00:00:13,210
our introduction to TIG welding,

3
00:00:13,310 --> 00:00:14,649
if you haven't, I highly recommend that

4
00:00:14,750 --> 00:00:16,420
you watch that video before you watch

5
00:00:16,520 --> 00:00:18,940
this one. It gives you a general sort

6
00:00:19,040 --> 00:00:20,920
of basic overview of the machine

7
00:00:21,020 --> 00:00:23,170
and settings and how set the machine up

8
00:00:23,270 --> 00:00:24,609
and things like that. What I'm going

9
00:00:24,709 --> 00:00:26,139
to do in this video is give

10
00:00:26,239 --> 00:00:29,359
you a demonstration on how I would

11
00:00:29,459 --> 00:00:30,879
complete a T fillet weld

12
00:00:30,979 --> 00:00:34,390
and the material I'm using is low carbon

13
00:00:34,490 --> 00:00:36,490
steel, five millimetre thick,

14
00:00:37,099 --> 00:00:38,710
40 millimeters wide and a hundred

15
00:00:38,810 --> 00:00:41,770
and fifty millimeters long. I have a two

16
00:00:41,869 --> 00:00:48,180
point four ceriated tungsten stuck out

17
00:00:48,299 --> 00:00:50,870
round about sort of six millimeters

18
00:00:50,970 --> 00:00:52,970
and I've got a size eight ceramic.

19
00:00:53,369 --> 00:00:56,690
I'm going to be using at six 500 filler

20
00:00:56,790 --> 00:00:59,810
wire. What I'm going to do first is tack

21
00:00:59,909 --> 00:01:01,250
the plates up, so we looked

22
00:01:01,349 --> 00:01:04,019
at the plates, are tacked in the center

23
00:01:04,260 --> 00:01:07,160
and at 90 degrees, if they're not quite

24
00:01:07,260 --> 00:01:09,169
at 90 once I've tacked them we can

25
00:01:09,269 --> 00:01:11,630
always knock them into position. So I'm

26
00:01:11,730 --> 00:01:14,930
going to put a tack on either end

27
00:01:15,029 --> 00:01:17,510
on the back side of where I'm going

28
00:01:17,610 --> 00:01:20,180
to be welding. This time I'm going

29
00:01:20,279 --> 00:01:22,790
to use no magnet as it has an effect

30
00:01:22,889 --> 00:01:42,989
on the high frequency arc. OK, so I'm

31
00:01:43,110 --> 00:01:51,129
fairly happy. In the center and I will

32
00:01:51,550 --> 00:02:46,399
move on and complete the weld. OK,

33
00:02:46,500 --> 00:02:48,739
what I was looking for on the completed

34
00:02:48,839 --> 00:02:51,500
weld is that we have nice even leg

35
00:02:51,600 --> 00:02:53,209
lengths and with it being five

36
00:02:53,309 --> 00:02:55,879
millimeter material, ideally I'd want

37
00:02:55,979 --> 00:02:57,979
five millimeter leg lengths as well.

38
00:02:58,830 --> 00:02:59,839
You may have noticed as well

39
00:02:59,940 --> 00:03:02,029
the technique I was using, I was rocking

40
00:03:02,130 --> 00:03:05,130
my ceramic. Some people walk in the cup,

41
00:03:06,149 --> 00:03:08,059
which just means that ceramic touches

42
00:03:08,160 --> 00:03:10,160
the both sides of the material

43
00:03:10,289 --> 00:03:11,599
and you rock it up and down as you move

44
00:03:11,699 --> 00:03:13,369
forward. Some people prefer this

45
00:03:13,470 --> 00:03:16,429
technique. Some people prefer just to go

46
00:03:16,529 --> 00:03:18,169
straight or sort of move up and down.

47
00:03:18,270 --> 00:03:20,369
All depends on what sort of weld

48
00:03:20,369 --> 00:03:21,750
you are looking to get.
