During the filler I ended up pitching the rod causing the root weld to run out of the weld. It made me so frustrated. I had did such a good job on T and lap joints that I just knew I could do a corner. Well I tried it on this Monday. My teacher showed me were I was going wrong and it made a huge difference in my weld. I was even able to fix the corner piece from Wednesday. This Wednesday I'm going to do a T corner combo. If I do a good job then I will move on to horizontal welds.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/9016791858821471195-3489939678767202514?l=lenawelds.blogspot.com' alt='' /></div>Lenahttp://www.blogger.com/profile/14732899428842588507noreply@blogger.com0tag:blogger.com,1999:blog-9016791858821471195.post-49934923260109566382007-05-05T14:04:00.000-07:002008-12-14T01:25:33.356-08:00<strong><span style="font-size:180%;"></span></strong><br /><br /><img id="BLOGGER_PHOTO_ID_5061187576994539202" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="http://1.bp.blogspot.com/_AEyAXBICkms/RjzzSTRhJsI/AAAAAAAAAAM/2tMpe08cfyA/s400/0536.jpg" border="0" /><br /><br /><div>I found this picture while shopping on eBay. According to the seller it is from 1918. It shows four ship welders posing for a picture. If you look closely you can see little burn holes in the pants of the gentlemen to the right. I think their welding"hoods" look neat.<br /></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/9016791858821471195-4993492326010956638?l=lenawelds.blogspot.com' alt='' /></div>Lenahttp://www.blogger.com/profile/14732899428842588507noreply@blogger.com0
