  • viascott- Biggest problem with that is not penetrating the base material (on a fillet) . It's too easy to flood the joint with filler and get no pen. I have students run a t-joint, 1 side only with their choice of filler rod technique (dip or lay wire). 99% of the time, the guys choose lay wire and those 99% always have lack of root pen. Simply chuck up the part in a vice and hammer the vertical member toward the welded side. Part mite not break but lack of root pen is evident.

  • @weldhawk1 I was welding "DOWN HILL" on the side of a flange. It was a round flange for shipboard ventilation. The shop I was in at the time, that's all we did was cut, build and weld miles of aluminum vent. When we welded fillets, outside corners or butts, one of the guys I worked with called it "caulking". We didn't dip the filler metal, we continually feed. It looked like a caulked bead of weld.(Production) And NO, it did not and would not CRACK.

  • @mrkendogg you hold the torch anyway you need to in production it's quicker to change your hand position than move the part. you set it up so you hold the torch like a pen [the correct way] for as long as you can. i used to have to weld lighting frames not so easy to move while it's not fully welded but you gotta still weld so change your hand position. though you very right about mig welding aluminum.

  • @mrkendogg sorry your wrong, i've done it on a 3mm aluminium sump using pulse on pulse mode.

  • Worthless!!

  • @mrkendogg You haven't seen my welds with a spoolmate yet man. Very smooth to the touch and a lot faster completed than tig too. By the way it's spelled "clean" not cleen.

  • It's hard to see anything is this video- not really teaching anything...

  • this video has no use or purpose to anyone...fucking useless

  • video of welding without tutorial is fucking useless !!!!!!!!!!!

  • Hey dude! it is possible to weld a 4mm thick composite aluminum sheet? and both side of the composite sheet has the same texture quality? i would really appreciate if u could answer this question thanks!
